EME - Antenna - Control - System
| Short description of the features | The system is based on a 80C535 Microcontroller |
|
- |
Computation of position (without PC) of moon,sun,Cygnus,Sagittarius,Cassiopeia,Taurus,Leo and Aquarius |
Demo - Version of the Controller
Digital position encoders you can get from http://www.usdigital.com . Look for the type A2-S-S, it has 0.1deg resolution and interfaces well to my system. If you prefer to build yourself, see my suggestions for a 0.5deg absolute encoder at the page : technical stuff . |
| - | Azimuth and elevation motor controlling for all targets plus two free choice positions | |
| - | Transmission of antenna position via single wire from antenna down to the controller in the shack | |
| - | Interfacing with
different position encoders is possible: 9..12bit a.)absolute (binary, BCD, Gray, Gray-Excess) b.)incremental (max. 100pulses/sec, reference mark) |
|
| - | Selectable stepsize for tracking | |
| - | Selectable offset for azimuth and elev. up to +/- 9.9 deg | |
| - | Relay control output right/left up/down ( 5V each ) | |
| - | Local operation by 4
buttons at controller, non volatile storage of all
parameters ( remote operation by PC is possible) |
|
| - | Real - Time - Clock | |
| - | 4 x 20 character LCD - display | |
| - | Audio dB - meter via RS232 and PC, scaling selectable, pictures can be stored to disk. ( See: Signal Plots ) | |
| Main
advantages: PC is not necessary for controlling (no interference!), single wire line from antenna (encoders) into shack, ready within a few seconds |

| Beside myself the
controller is used by HB9BBD, HB9Q, IK3MAC, OE5EYM and . . . |
Marc, ON5RR, took over the job from me assembling kits, modules and also the whole controller. If you are interested, please send me an E-mail: j.fasching@eduhi.at He has also written a more detailed description: EMEcontr.doc |
