Summary. 1)Main features. * Decoding the NMEA sentence of 11 types, to understand it displays in real time easily. * Sentence of specification and the sentence which is not supported can be displayed with the text. * The sentence which has checksum error and the like can be displayed with the text. * Graphical representation Sky-plot and SNR. * It displays the mean value of latitude and longitude and altitude. * Calculating 2drms, it displays. * Optional command can be forwarded to GPS. Calculating checksum automatically, it adds (as a calculator of checksum it can utilize). It can record the command which it forwards every type of GPS up to 100, can reuse. Also transmission of the binary code is possible. Checksum is added to SiRF and UBX binary command automatically. * The NMEA data which it receives can be retained in the text file. * It can play back can display the NMEA log file. Playback fast forward and step playback being possible, playback of reverse direction is possible. The playback point can be configurated optionally with the drag of the track bar. The playback data can be output to the serial port. * The UTC time of GPS and time difference of the personal computer can be displayed in real time. * Change of UTC time of RMC sentence is monitored, the report is displayed in when it fluctuated. It can monitor Missing the sentence. and leap second correcting after the cold starting. * The elapsed time which fix after sending out the GPS command of Cold start etc., can be displayed. * It can display GSA and GSV sentence to 16 satellites. * Indicatory language can designate change as Japanese and English. 2) Install. In installation just copies executable file NMEA.EXE and NMEA.INI in the suitable folder. Because registry is not used, it can Un-install with only the deletion of NMEA.EXE and NMEA.INI. Note1) When old version is used, NMEA.EXE only to overwrite copy, according to need NMEA.INI the GPS command and the like of please merge. In initial condition being to become English mode, "Langage" -> "Japanese" it becomes Japanese indication. Please rename "NMEA_Jp.INI" to "NMEA.INI" to use the setting file of the Japanese notation ("NMEA.INI" is renamed to "NMEA_Eng.INI" etc. in advance) . Note2) When "compatibility mode" is set as "Windows XP (Service Pack2)" by a property of an executable file or a short cut in Windows Vista, it becomes possible to detect an effective serial port. Note3) With "Windows Vista" Administrator is necessary in correction of time. When "Run this program as an administrator" check is inserted with the executable file or the property of shortcut, it reaches the point where being promoted dialogue to Administrator is indicated in when starting. 3) Operating condition. Operational OS: Windows Vista, Windows XP, Windows 2000. RS-232C baud rate: 300 to 115,200bps. RS-232C port number: 1 to 99. Handling sentence: GGA, RMC, GSA, GSV, GLL, VTG, ZDA, DTM, HDG, HDM, HDT, SMD. 2. Option setting (Option). The option setting form opens with "Option" -> "Option setting". * GPS receiver. It selects the GPS receiver and it sets parameter. GPS name. The GPS receiver which you use is selected. In case of the GPS receiver which is not to the list, inputting GPS receiver name and other parameters, when it clicks "OK" button, it can add. Alias specification is possible, if it inputs with the form of = and the "OK" button is clicked. Example) i.Trek M3=BT-339. Selection of "i.Trek M3" uses the data of "BT-339".

When start sentence is not included in the log, playback speed becomes abnormal. Time synchronization (Sync Adj). The number of compensation seconds for adjusting a time synchronous delay is specified (0 to +-5.0 second). Inputs the lag time of time output of the GPS receiver at the second unit (The input below a decimal point is also possible). Note) When the output timing of a GPS receiver does not synchronize with UTC time and it does not output under a second to UTC, the correction for less than +-0.5 seconds is impossible. Furthermore, since timing changes by the change in the number of output sentences, or the number of the characters in a sentence, a precise synchronization is not expectable. DEL button. Information of the GPS receiver which presently is selected everything is deleted from the setting file (NMEA.INI). Exception. When select the "Not supported & not Private only" of "GPS Command/Report", the sentence which excludes indication is appointed. It can utilize in order to make the indication of status and the like when initializing easy to see. When multiple sentences are appointed divide with ",", there is no space with describe. Ex.) $GPBOD,$GPRMB,$GPRTE,$PGRME,$PGRMM,$PGRMZ Max Sat. The maximum number of indicatory in GSV sentence indication satellites is appointed. In case of 12 satellites 3 sentences and in case of 16 satellites it displays 4 sentences. At the time of 12 satellites in case of 3 sentences and 16 satellites it indicates 4 sentences. When "Default" is selected, you follow the setting of "Max 16 satellites" indications of option setting. Having done always in 16 satellite indicatory modes, in regard to operation there is no problem. SNR graph. The indicatory range and threshold level in the SNR bar graph it appoints. This is used only in order to make the graph of SNR easy to see. Threshold is indicated with the dotted line and uses in the standard of reception possible level (does not indicate the value of 0). * Option. Other option items are set. Sky-plot by linear: When check is removed, the cosine graduation is used for angle of elevation. Ignore Check-Sum: When it checks, checksum error is ignored. Max 16 satelites: Default of the maximum number of satellites with GSV sentence is designated as 16 satellites. In case of not yet check it makes to 12 satellite 3 sentences. Note) Individual setting every of GPS receiver takes precedence. ddmm.mmm format: Latitude longitude of GPS output is indicated with type of original "Degree,Minute". Resolution of latitude longitude output (the number of output below the decimal point of minute) you can verify. Automatic re-origin: Starting point renewal is executed automatically when mean place above approximately 3m leaves from starting point (Migration length in order not to have an influence on the calculation of 2drms, makes the 0.1m step). Hint display: When check is removed, it stops doing hint indication. When hint indication is troublesome, please remove check. UTC fluc.(RMC): Warning value of UTC interval fluctuation between RMC sentence (sec.). * Local time. The data in order to convert UTC to the local time is set. Time diff: The time difference of UTC and the local time is set (in Japan 09:00:00). Short name: Abbreviation of the time zone is set. Auto: When it checks, the setting of OS is acquired automatically. An abbreviated name pickup and creates only a capital letter from the time zone name of OS (Only when a time zone name is returned with an English character). It specially converts it into "JST" for "Tokyo Standard Time" or "東京 (標準時)" the Time zone name. * Serial port. It sets the serial communication port. Port: Number of the serial port which connects the GPS receiver is set. Baud: Transmission speed of the serial port (baud rate) it sets. Log Out: When it checks, the data at the time of log playback can be output to also the serial port(Verification dialogue is displayed in when starting the playback). It can utilize in the test of the data logger etc., as a GPS simulator. Re-connect: When it checks, automatic re-connection of a serial port. A serial port is among open, and when a non-signal state continues, re-opening of a serial port is performed. A connection cycle follows a setup of "ReOpen" of "GPS Command/Report" (Min: 5Sec). It is useful to recovery of the broken link of Bluetooth. Scan: The serial port where GPS is connected is searched. After appointing transmission speed, it clicks "Scan" button. When the "Abort" button is clicked, search is discontinued. When the "Retry" button is clicked, search is reexecuted. When GPS is not found, please try enlarging waiting "Wait" (1.5 to 5 recommended). Note1) When specification "Baud" differs from the transmission rate of GPS largely, there are times when GPS cannot be detected. Note2) It can detect virtual serial port such as BlueTooth adapter regardless of transmission rate. * Printing and copy. Popup menu - it indicates with the right click of the mouse, can copy to printing and the clipboard of form image. 3. Printing and copy (Main Form) "File" -> "Print" the Form picture the hard copy is done in the printer. It is copied to also the clipboard. The paper of A4 size is necessary. "File" -> "Copy" image of Form is copied in the clipboard. 4. Record of data/playback. * Playback indication of GPS data. It replays the data file which was saved in the record and it displays data. When file name is appointed with "File" -> "Start Replay", it becomes log playback mode and the track bar and the operation button are appear. It ends log playback mode in "File" -> "Stop Replay". When ">" the button is clicked, playback is started. When starting the playback output interval of the original data it plays back unrelated always at 1 second interval, but refresh rate at each time the ">" button is clicked becomes quick. Point of playback is indicated with the track bar, When the track bar the drug is done with the mouse, the playback point can be modified. When "+" button is clicked, just 1 data replay in forward direction, when "-" the button is clicked, just 1 data plays back in opposite direction (step playback). When "||" button is clicked, playback is pause. When "Log Out" check box of the "Serial port" section of option is checked, when starting the verification dialogue whether or not it outputs the log playback data to also the serial port of, is indicated. The drug & drop doing the log file in main form, it starts log playback. However, during of log recording and while playing back are ignored. Form size can be minimized if it clicks on "maximize/minimize" icon. If it clicks once again, it will return to the original size(Only when Log playback data is outputted to a serial port). * Record of GPS reception data. The raw data from GPS almost that way to the text file it records retains. Appointing file name with "File" -> "Start Recording" it starts record. When extension name is abbreviated, ".nmea" is added. Record is stopped by "File" -> "Stop Recording" and a file is closed. Note) When extension name of default is modified, Setting file "NMEA.INI" the part of "NmeaExt=.nmea" of the [Option] section is modified. 5. GPS Command/Report. The GPS command/report indicatory window opens in the "Tool" -> "GPS Command/Report". The drug doing the window corner, it can expand and reduce the size of the window. * GPS command transmission (GPS command). Optional command is send to the GPS receiver. Because it has automatic operation addition of checksum and display function, checksum calculation is unnecessary. Inputting GPS command, when it clicks "Send", it transmits the command character string to the GPS receiver, that command is registered to the drop down list. It can record every GPS receiver to 100 commands. When "Delete" button is clicked, the GPS command which it is selective is deleted from record in "NMEA.INI". To include control character to GPS command, the escape sign "\" continuing, hexadecimal character string 1 or 2 columns it appoints (0-9, A-F, a-f). "\" as for itself "\\" , "|" as for itself "\|", ";" as for itself "\;" The way you describe. When the space is included "\ " or "\20" you describe. Ex.) Input character string and output (hexadecimal notation) correspondence. a\12b -> 61 12 62 x\ay -> 78 0A 79 x\yz -> 78 79 7A a\012 -> 61 01 32 a\\b -> 61 5C 62 a\|b -> 61 7C 62 If the beginning of command A0 A2 then regard as SiRF binary command, when checksum is abbreviated, checksum and End-sequence(B0 B3) are added automatically. If the beginning of command B5 62 then regard as UBX binary command, when checksum is abbreviated, checksum are added automatically. Concerning forwarding and CheckSum addition control of multiple commands later description "11. About the setting file" it is reference. * Option. Fix time: It displays the elapsed time which fixs after sending out a GPS command. If a time display is clicked, a display will disappear and a check box will appear. Chk-Sum: When checksum is not included in command, checksum is added. If the end of a command character sequence is "*", CheckSum is not added, but "*" is deleted and sent out. Cr: The Carriage-return code is added to GPS command (usually checks). Lf: The Line-feed code is added to GPS command (usually checks). * Indication of non support sentence and selective sentence. Only the sentence which is not supported, only the sentence which is selected, selecting all sentences, it can indicate. Indicatory contents are selected with combo box of the left top. Not supported only: Only the sentence which is not supported with the NMEA monitor is indicated. Not supported & not private only : Except for the "Exception" sentence specified as the option, it displays from the above-mentioned display. (Indication of status when initializing etc., can be made easy to see). Display all sentences: All reception data are indicated. Only the corresponding sentence is displayed except the above. When "Hex" check box is checked, being to indicate reception sentence hexadecimally, verification of the binary code of non indication can do with text mode (the data of indicatory end does not change). When "Time" check box is checked, adding UTC time to the forefront of reception sentence, it indicates. As for the first 1 character "N" of line does not support, "?" unknown sentence is displayed. When indication exceeds 30KBytes, it keeps being deleted from old line. A mouse cursor is put on a boundary with an error sentence display part, and if cursor form drags in the position which changed to the up-and-down arrow, the height of a display domain can be adjusted. Note) The time of the head of a line is generated and added from GPS data. When SiRF binary is received, "SiRF-Bin" it indicates in place of time. When UBX binary is received, "UBX-Bin" it indicates in place of time. * Error sentence. Only the sentence which has error is indicated. In addition the reception data is indicated in during playback log transmitting. When "S" is attached to the head of a line, the sentence of a checksum error is expressed. When "R" is attached to the head of a line, the RS-232C receiving character sequence under playback log transmission is expressed. When "Hex" check box is checked, reception sentence is indicated hexadecimally. When "Time" check box is checked, adding UTC time to the forefront of reception sentence, it indicates. UTC time and this time of RMC sentence immediately before are compared. If above the value which difference of the last time specifies with option as description below alert warning is displayed(is above differential time 60 second, it does not output). A warning output is not performed if specification of "UTC fluc.(RMC)" of an option is zero. * UTC step changed : 1.00 to 2.00Sec. UTC(RMC)=12:34:56.789 When indication exceeds 30Kbytes, it keeps being deleted from old line. Note) The time of the head of a line is generated and added from GPS data. * RS-232C. A status display and control of RS-232C are performed. DTR, RTS: When it checks, the signal line which corresponds is made active. Immediately after of the RS-232C opening is always active. DSR, CTS, CD, RING: When being active, it indicates with red (in every 1 second renewal). F.Er: Framing error. P.Er: Parity error. O.Er: Buffer overrun Error. NoSIG: Serial port input more signalless 2 to 3 seconds. Function of push button. Open: The RS-232C port is opened. Close: The RS-232C port is closed. ReOpen: Closing the RS-232C port, it re-opens after the designated time. * Printing and copy. Popup menu - it indicates with the right click of the mouse, can copy to printing and the clipboard of Form image. Also printing and the copy of the corresponding text can do with the right click on combo box and the memo component. 6. Indication of Track and averaging value(Average display). The mean value of Latitude Longitude, Altitude and Track can be indicated in "Tool" -> "Average display". * Indication of mean value. If a "Start" button is clicked after configurating the upper limit of HDOP to averaging, averagingn will be started, and averaging will be stopped if a "Stop" button is clicked (When the specification value of HDOP is blank, it averaging without restriction by HDOP). The data which is not Fix is disregarded and is not used for averaging. When the GSA sentence is outputted, only the data at the time of 3-dimensional positioning is used for an average altitude. "The number of times of an average of latitude longitude" and "the number of times of an average of altitude" are respectively displayed on the column of "Count". 2drms display the theoretical value of the radius of the circle which is horizontal position accuracy and is supposed that 95% of all positioning points are included (It is proper, but if determination it does not do in position fixing, there is no meaning). Because it calculates elapsed time from the data of GPS, even in at the time of log playback it can indicate correctly. When "Reset" button is clicked, value is initialized. Note) Please observe the measurement of 2drms for about 12-24 hours in open sky. Measurable quantity fluctuates with influence of measurement region and condition of the satellite etc. * Indication of Track. With "Track" the locus which designates the position when starting averaging as standard is displayed with the dot. When "Average" tab is clicked, change of mean value is indicated with Track. It cannot indicate with polar nearby high latitude area correctly. To be offered by the one for drift verification of GPS output mainly, as for the indicatory range the +-0.5 to +-200 m. When "Origin" button is clicked, present mean value (within +-5cm) setting to the start position, it continues levelling (For storage capacity conservation logarithm compressing, because it retains the point, resolution has become non-linear. Because of this at each time "Origin" is executed, being proportionate to migration length, Track becomes deformed). When "Rreset" button is clicked, also Track is cleared. When the mouse the right is clicked, popup menu - is indicated. Clear Track: Clearing present Track, only new Track indicates. Track by 1 pixel: It indicates Track with 1 pixel. Track by 4 pixels: It indicates Track with 4 pixels. Print Form : Image of Form is printed in the printer. It is copied to also the clipboard. Copy Form: Image of Form is copied in the clipboard. Distance: Resolution. 0.5m:0.04m, 1m: 0.05m, 2m:0.08m, 5m:0.16m, 10m:0.3m, 20m:0.56m, 50m:1.4m, 100m:2.7m, 200m:5.4m. Restriction item. 1) When GGA sentence is not output, it cannot averaging MSL altitude, (In order to substitute a RMC sentence). In this case HDOP of GSA sentence is used, but when either GSA sentence is not output, ignoring the appointment of HDOP, it averaging. 2) When neither of GGA and RMC is output, it cannot indicate mean value and Track. 7. Time correction of personal computer (Clock synchronization). When the GPS receiver Fix and RMC or ZDA sentence is output, The calendar timer of the personal computer is adjust with "Tool" -> "Clock synchronization" making use of the GPS time data. When the correction quantity exceeds 30 minutes, verification dialogue is indicated. With Windows XP and the like it is necessary to have logged on with the account of the administrator. Note 1) The time lag of the UTC output of a GPS receiver is set as "Sync Adj" of the "GPS receiver" of an option, and the time of PC can be revise. Note 2) When the cold start or long time it is not used, depending upon the GPS receiver, immediately after the GPS fix, there are times when it cannot revise leap second just. In this case after 13 minute after the Fix or more elapsing, please perform. Note 3) When RMC is not output, for deciding the determination state, GGA or GLL sentence is necessary other than ZDA. Note 4) With "Windows Vista" Administrator is necessary in correction of time. When "Run this program as an administrator" check is inserted with the executable file or the property of shortcut, it reaches the point where being promoted dialogue to Administrator is indicated in when starting. 8. Indication of differential time of the GPS UTC and PC-time and sentence reception time. Form is opened in "Tool" -> "Time lag of GPS to PC", differential time of the UTC time of GPS and personal computer time (GPS time - PC time), reception time of sentence is indicated in each sentence in real time. Please use after synchronizing the clock of a personal computer with a time server etc., (It is desirable that it can synchronize in the accuracy for less than 0.1 second). "Sakura Watch network time client" by Mr. UNO Shintaro is recommended if it uses it in a Japanese mode. inflation! - uno's homepage: http://www.venus.dti.ne.jp/~uno/ File: http://www.venus.dti.ne.jp/~uno/software/skrw/skrw021.lzh Since it has the influence of the number of serial data bytes, internal processing delay, etc., Under a second is regarding it as a rough standard. Since timing changes also in the existence of a GSA, GSV sentence, when the sending-out sequence of a NMEA sentence can be specified like i.Trek Bluetooth GPS, it will be good to specify GSA and GSV to be an end. When the "Statistics" check box is checked, the maximum value, minimum value and the mean value of the time difference are displayed. The display is discontinued when the check is removed and statistics are clear. Popup menu - it indicates with the right click of the mouse, can copy to printing and the clipboard of Form image. Note 1) When there is a differential time above +-12 hours, differential time cannot be indicated correctly. Note 2) If "Statistics" check box is off and Form is closed when unnecessary, Unnecessary calculation processing is not performed. Note 3) Usually, resolution of the calendar timer with the Windows machine is approximately 15.6mS, but there are times when occurs the processing delay of several dozen mS or more with such as task waiting. 9. Indication of reception data. * Data display of each sentence. Whenever it receives data, a data display is updated, and the title background of corresponding sentence blinks. Error status is indicated in the right side of sentence title. E: Checksum error, L: The number of items excessive, N: There is no checksum. DTM, HDG, HDM, HDT, SMD sentence becomes change indication (simultaneous indication is not possible). When the letter of "D,G,M,T,S" above the left is clicked with the mouse, indicatory contents are changed. DTM: $GPDTM, HDG: $HCHDG, HDM: $HCHDM, HDT: $HCHDT, SMD: $IISMD When the character of "C" above the left is clicked with the mouse, the display window of the CHN sentence is opened. CHN: $PMTKCHN Correspondence of sentence sign and characters on screen line. GGA. GPS Quality Indication = 0: Invalid 1: SPS fix 2: DGPS fix 3: PPS fix 4: RTK fix 5: FloatK fix 6: Estimated 7: MANUAL input 8: Simulator GLL, RMC. Status = A: Valid V: Void VTG. True Course = numerical value is blank, sign "T" is not indicated. Magnetic Course = numerical value is blank, sign "M" is not indicated. GSA. 2D/3D mode = A: AUTO M: MANUAL Mode = 1: Not fix 2: 2D fix 3: 3D fix The mode of VTG, GLL, RMC. A: Autonomous D: Differential E: Estimated M: MANUAL input S: Simulator N: Not valid Each sentence commonness. When numerical value such as altitude and speed is blank, unit symbol "M, K, N" and so on it does not indicate. Note) Depending on a GPS receiver, the altitude from WGS-84 ellipse to a receiver is output to the MSL altitude of a GGA sentence (Especially in the case of the receiver which does not display geoid quantity, it is careful.). In this case geoid height subtraction those which are done become altitude from indicated value. Moreover, although an MSL altitude is outputted in TOKYO datum, keep in mind that there is also a GPS receiver which outputs the altitude from WGS-84 ellipse to a receiver in WGS-84 datum. Concerning the geoid height of Japan the Web page of national geographical institute "Shape of the earth is measured", Please refer to http://vldb.gsi.go.jp/sokuchi/shape.html Ref.) The geoid of Tokyo stations height has become approximately 36.6 m. * Position indication of satellite (Sky plot). GSV sentence is necessary in the indication of Sky plot. A GSA sentence is required to indicate the satellite in use by classification by color. Display position. As for azimuth 0 degree as for "N", and 90 degrees as for "E", and 180 degrees "S", and 270 degrees correspond to "W". It converts angle of elevation to the distance of radial, the center 90 degrees, circle outside corresponds to 0 degrees. Circle inside is angle of elevation 60 degree and 30 degrees. Indicatory mark. Satellite number indicatory mode. A satellite number is displayed. The used satellite in GSA is expressed as the background of Red(fixed)/Yellow(non fixed). SNR indicatory mode. It indicates SNR, Red(fixed)/Yellow(non fixed) indicates the use satellite with GSA with the background. SNR with indicates the satellite of blank "+". Indication of direction. In outside circle travelling direction is indicated with the dot of blue. * The indication of SNR. SNR each of satellite is indicated in the bar graph. The bar of a satellite in use is painted out black(depending on GSA sentence). Display order follows a GSV sentence. Numerical value expresses a satellite number (PRN). 10. Change of a display language. With "Language" -> "Japanese" Japanese indication, with "Language" -> "English" it becomes English indication mode. Display font can be specified by "Language" -> "Font". Keep in mind not settled within the display limit depending on the kind or size of a font. As for Japanese font name of default "MS Gothic", as for size it has become "9". As for English font name of default as for "Courier New" and size it has become "9". It can appoint also the attribute of Color and the Bold type etc., but the fact that it save in the setting file is only font name, character set and font size. 11. About the setting file. Setting is retained in Text file "NMEA.INI". When the folder with the configuration file is read-only, it copies onto folder %APPDATA%\NMEA\ and it uses it. %APPDATA% is a folder displayed to input by the DOS prompt as "echo %APPDATA%" . * GpsData section. The number of the maximum satellites, name of a GPS receiver, range of SNR graph, threshold value, start sentence, GSA sentence (12 or 16), time synchronous number of adjustment seconds, and an exception sentence are specified. Range specification is used in order to make the graph of SNR legible, and it is specified in order of a maximum and a minimum according to a GPS receiver. A threshold value is displayed by the dotted line on SNR graph (it does not display if 0). As for start sentence you use for the pause detection at the time of log playback (default it makes GGA). When the maximum number of satellites of GSA sentence is abbreviated, follow the setting "Maximum 16 satellites" of option. When the number of adjustment of time synchronization seconds is blank, it does not revise. The comma "," with dividing, plural it can appoint exception sentence. When would like to change the indicatory order of the drop down list, please correct with text editor etc.,. Example) [GpsData] Not Selected=99,0,0,GGA,16 GM-48-AT=60,20,30,RMC,16,0.36, CRUXII/BTGPS=60,13,28,,12,0.9 508PC=60,0,15,,12,1.4 PCGPS=60,15,30,,12 GM-38=70,25,35,,12,0.5 GPS65EZ=20,0,3,,12,1.2,$PKODA,$PKODG SiRF(general)=60,0,0,,12 * GpsCmd XXXX section. When GPS command sending is executed, is recorded automatically (GPS type name enters into XXXX part). It can record GPS command every GPS receiver up to 100. When would like to change the indicatory order of the drop down list, please correct with text editor etc.,. Although a key may be suitable if it does not overlap, it is rewritten by the form of "Cmd.." at the time of preservation of a file. Plural commands are sending, "|" with it divides (approximately 1 seconds pause between command). When pause time between command is not enough, "|" it adds (per 1 approximately 1 second increase). Baud rate after the GPS command forwarding can be specified to the comment part ( \B9600\ The way numerical value is surrounded with "\B" and "\" ). After of the semicolon is ignored regarding comment. If end in the command character string "*" it does not add CheckSum and "*" deletes and sending (Option setting having become "Chk-Sum" it is ignored). In case of the binary command of SiRF and UBX CheckSum (2 bytes) it can add. When the string surrounded with "\\" and "\\" in a comment part is described, the string is indicated, and execution confirmation is performed.

CaptureDelay : Appoints the waiting at the time of Form capture (default is 8). When the sub menu remains in the picture, please enlarge value (the 50mS unit). IgnoreSpace : After space in the NMEA sentence is deleted, it analyzes it for "1". It analyzes it as it is for "0". ReadExt : The extension name of the NMEA log file for reading is specified. Default value: .nme.nmea.nma.log.txt Concerning other section please refer to the comment of the "NMEA.INI" file. 12. Command line option. A setting file is specified to be a command line, It can use another setting file in place of "NMEA.INI" of default. As for extension name of setting file it must be ".INI". In addition also it is possible to appoint the Log file. Extension name of the Log file makes 4 types of ".nmea", ".nme", ".Log", ".txt". When a drive name and a path are omitted, It shall be in the same folder as NMEA.EXE. When the setting file does not exist, it is make up anew. Example) NMEA Other.ini "Other.ini" in same folder with executable file is used. NMEA C:\GPS.ini "GPS.ini" of C: drive route is used. NMEA Other.ini Test.Log Setting file "Other.ini" to read, and "Test.Log" is played back. NMEA Test.nme Log file "Test.nme" is played back. When the GPS receiver 2 or more is connected to 1 PC simultaneously, it is convenient if you create the shortcut of NMEA.EXE (The created shortcut is right-clicked, a property is chosen and a setting file name is added to the end of a link place). Note) Setting file and Log file the drug & drop doing in the icon of NMEA.EXE, it is possible also to start. However, during of log recording and while playing back are ignored. Setting file and the Log file only each 1 file are effective (When plural is appointed, the first file is used). Automatic record start of NMEA data. When "/W" is added to the log file name of the command line, the record is started automatically by the file name. When the file name is omitted, beginning date (yyyy-mm-dd_hh-mm-ss) is made a file name. When the blank is included in the file name and path, it encloses with double quotes. If the log file has already existed, it adds it to the file. Ex) NMEA Test/W Data is recorded in "Test.nmea" of the same to execution file folder. NMEA /W It records by the file name "
