Remote Control for ICOM Transceivers via PC Distribution : DF5FF,Landolt-Computer,Tel. 06181 - 45293 System Requirements : IBM PC/AT or 100 % compatible Processor at least 80286 VGA-Adaptor for Spectrum Installation : Change drive to A: or B: Type install, Return MENUE INFO: -This file. MENUE COM 1/2: -Selection of COM 1 or COM 2.Default is COM 1. -Selection of 1200 or 9600 Baud.Default is 1200 Baud. Take care with 9600 Baud when using long cables between device and interface or more than one device connected to ICOM-Bus. MENUE DEVICE: -Selection of ICOM device adress (Default=4) and datalength (Default=4), see examples at end of file. (Enter device adress in hex format, for example adress 1C is entered as "1" and "C") -When starting, the program tries to read textfile C:\ICOM\ICOM.CFG for your personal configuration. Line of file Example Meaning 1 1 COM 1 selected 2 1200 1200 Baud selected 3 14 Device adress for IC 475 4 5 Datalength 5 byte 6 - 25 Frequency and mode data Online Memory MENUE FILE: -Enter frequencies in MHz "." kHz "," optional 3 decimals for your frequency database. Examples: Input File .5 .500,000 14 14.000,000 28.5 28.500,000 144.350,5 144.350,500 1296.350,000 1296.350,000 -Possible modes are lsb,usb,cw,am,fm.Small letters are possible, program converts to capital letters. If no mode is entered, "USB" will be selected. -C:\ICOM\EXAMPLE is an example file for working with PC Memory or Memory Scan.It shows data format if you want to edit files with a text editor. MENUE PC OPERATION: -Menue Online: Manual operation of device and entered data will be shown on PC display. Frequency, date and time as large seven segment, other information as normal letters. Device is requested continuously to send out actual data. Enter Push to enter data, push twice to stay on frequency and change only mode Escape Return to Menue F1 Help F2 Show Online-Memory List a Selection of VFO A b Selection of VFO B s Enter frequency step for Arrow left/right f Store displayed frequency, mode, PC date and time in C:\ICOM\DATA.TMP m Select Online Memory channel 1 - 20 ( C:\ICOM.ICOM.CFG ) d Show PC date t Show PC time n Select narrow bandwidth w Select wide bandwidth Arrow up/down Frequency step up/down Mode Step AM,FM 1 kHz LSB,USB 100 Hz CW 10 Hz Arrow left/right Frequency step up/down, Default 25 kHz, select other steps with "s" Depending on Icom device displayed 1Hz-frequency data may be dummy data. -Menue PC Memory: Select frequency and mode in any database file and send data to device. If program finds a mouse installed, select with mouse. -Menue Scan/Spectrum: Enter lower and upper frequency, mode, scanstep and holdtime. Start Any key Stop Return 1 Scanstep up Return, if stopped before Scan again Any key but not Return Escape Return to menue Devices connected to ICOM-Bus are not adressed because of transmission time via serial port, every device scans inside its frequency range. With additional equipment spectrum operation and monitoring is possible (VGA-Mode), see remarks. -Menue Memory Scan: Select any database file for scanning, then same operation like Scan. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Examples for ICOM adresses and datalength : Adress: Datalength: R 71 : 1A R 72 : 32 R 7000 : 8 R 7100 : 34 R 9000 : 2A IC 271 : 20 275 : 10 375 : 12 471 : 22 475 : 14 5 575 : 16 725 : 28 726 : 30 735 : 4 4 751A : 1C 765 : 2C 4/5 adjustable at device 761 : 1E 781 : 26 970 : 2E 1275 : 18 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ A positive signal ( TTL level may be possibly enough ) connected to RI of COM-port used for ICOM interface stops scanning while operating Scan/Spectrum or Memory Scan. Scanning goes on with RI-signal going to ground or pushing any key (1 scanstep up with Enter). See your ICOM-Manual for polarity of SQL-signal at ACC-port, invert SQL-signal if necessary. Holdtime must not be too short to allow AF to stabilize. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Remarks for Spectrum - Operation : -Operate COM-port with 9600 Baud because of serial transmission time and faster mode of operation. Adjust ICOM device to 9600 Baud internally by jumpers. -Operation of devices will be in ICOM-Mode 0, no device message. -Disconnect RX and TX at ICOM-Bus in your interface ONLY! for spectrum operation. Connect an A/D converter with serial conversion to RX of interface. (With RX and TX connected you will see the converted remote messages for the device) -ICOM data format (hex) : FE_FE_00_PC Adress_00_Remote data (4/5 byte)_FD -After end of holdtime the A/D converter is requested to send one character (8 bit) : Startbit_1 character_1 Stopbit no parity At DTR of COM-port used for interface will be a Sync-signal for A/D conversion.The A/D converter may not be allowed to send continuously because of receive-buffer overflow of COM-port. -A COM-Monitor (Monitor.exe) is supplied with the program to make checking easier. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Simple ICOM interface : +5 V 2 X C RS 232 |------4,7 n || 10 uF--------Gnd ICOM-Bus R GND o---------- 10 K | |----------------------------------L 1uH--------o Gnd | | | R |-- C | | TX o--47 K---------| | | o K| |-- E | | | D | R C | 1N4148 | 6,8 K 100 p | A| | | | | | | | | | Gnd Gnd | Gnd Gnd RTS o--- | | | CTS o--- +5 V | | | R | 4,7 K | | | C | | RX o--------------------| | |---------- --| | E | | | R | 22 K | | Gnd Gnd An Interface with all necessary cables is also available from ICOM +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Not all functions of the program are available with every ICOM device !
