-
- ARSENE is a mini satellite built by french RACE radio amateur organization.
- Its mass is 158 Kg and its orbit 20 000 - 36 000 Km with zero degrees
- inclination. The output power is 15 Watts on VHF.
- It has three AX25 standard 1200 bauds AFSK FM packet transponders with three
- uplink frequencies on 435.050-435.100-435.150 Mhz.
- The frequency of the downlink and of the AX25 beacon is 145.975 Mhz.
- This beacon will send telemetry giving the status of radio modules
- and electrical equipments aboard the satellite.
-
- Hardware requirements for copying the telemetry in real time:
- A VHF FM receiver, a standard packet Terminal Node Controler with no special
- modem (i.e. bell 202 standard) a PC with serial port connected to the TNC
- using 8 wires ( wires 2 to 8 plus wire 20). Signal strengh should make
- ARSENE easy to copy with a 145 MHz yagi antenna with 13 dB gain. Although
- signal is transmitted with vertical linear polarisation, a circular
- polarisation receiving antenna could be better.
-
- This real time telemetry decoding program will run with any color graphic
- adaptator. The monitor can be black and white but, of course, full colors
- effects will not be performed unless a CGA, EGA or VGA monitor is used.

- A- Distributed file catalog
- ===========================
-
- SIMU.BAT Batch for ARSENE reception simulation (no TNC required)
- TELEM.EXE The telemetry decoding program
- TELEM.CFG Configuration file with telemetry channels equations
- TELEM.COL Color configuration file
- TELEMCOL.COL Color configuration file
- TELEMB&W.COL Black and white color configuration file
- CONFIG.TNC TNC configuration file
- ESS.COM Interrupt driven Serial I/O driver version 1.11
- written by Gerard FC1EBN (also author of TPK);
- Its performance are such that you can run at up to 19,2 Kbd.

-
- B- Installation
- ===============
-
- First, protect your original floppy and make a backup copy.
-
- TELEM.EXE will run with a TNC-2 Prom 1.1.5 or higher version or compatible.
- The configuration file CONFIG.TNC was programmed for a TNC-2 connected to
- serial port COM1 with a 9600 bauds speed, 8 bits, no parity. In order to
- modify COM number, speed or format, you only need to change the first three
- lines in CONFIG.TNC file. The third line that represents the format is coded
- like the following:
-
- XYZ with : X = N no parity
- X = E parity even
- X = O parity odd
-
- Y = 8 8 bits data
- Y = 7 7 bits data
-
- Z = 1 1 stop bit
- Z = 2 2 stop bits
-
- The next three lines in CONFIG.TNC initializes the TNC serial i/o parameters.
- AWLEN 8 tells the TNC to run 8 bits serial communication
- PAR 0 tells the TNC to run 0 parity serial communication
- RESTART make the previous instruction active.
- These instructions are for a TNC2. You can modify it for your particular case.
- For example they will not work with a TNC-20 that use E71 serial parameters
- only.
-
- LCALLS parameter is set for ARSENE-1 callsign. If ARSENE satellite callsign
- is changed to FX0ARS-1, change here the corresponding callsign.
-
- You can choose color display or black and white display by copying either
- TELEMB&W.COL (for black and white) or TELEMCOL.COL (for color) to TELEM.COL
- file.
-
- Before running TELEM.EXE program, you must install the serial driver ESS.COM.
- For example, if your TNC is connected to port COM 1, you type ESS 1 or include
- a line with "ESS 1" (without quotes) in the AUTOEXEC.BAT
-
- TELEM.EXE program must be run from the same directory where the files
- TELEM.COL, CONFIG.TNC and TELEM.CFG are. When TELEM is run without argument
- it looks for a TNC connected to the serial port and make the initialization
- of the TNC.
-
- C- Usage
- ==========
-
- To run TELEM.EXE, you only need to enter command "TELEM".
-
- If you would like to simulate satellite telemetry reception you can run
- the program in simulation mode, even without connecting it to a TNC. You
- should use the batch file SIMU.BAT or type TELEM SIMU at the DOS prompt.
- In that case the serial driver ESS is not necessary. Random number are
- generated inside the program.
-
- In the present version there are only 5 possible commands when TELEM is
- running, using the function keys:
-
- - F1 : To acknowledge a new alarm (there is a beep warning and the values
- that triggered the alarm by outpassing the normal values are
- blinking).
-
- After pressing the F1 key, the beep is stopped and the figures that
- start the alarm stay in red except if the values return to normal.
-
- - F2 : To toggle the display from real values to rough figures send by the
- satellite and vice versa.
-
- - F3 : To toggle the display from real time telemetry to archived values.
- You can move through the records using Page UP and Page DOWN keys.
-
- - F4 : To toggle the display from analog telemetry to STATUS channels.
- You can toggle screens back and forth. A change in any STATUS
- channel makes the corresponding item blink. F1 key will stop the
- blinking.
-
- - F10 : To quit the program.
-
- D- In case of difficulty
- =========================
-
- 1/ The program displays "The TNC-2 is not responding" :
-
- Possible causes are :
-
- - there is no TNC connected to the serial port !
-
- - the serial port configuration is not compatible with your TNC:
- check carefully the first three lines of CONFIG.TNC file;
-
- - ESS driver is not loaded: load it typing ESS 1
- (1 for COM1: depending on the port number you are using)
-
- - the ESS driver is locked (for example after using a communication
- program like Procom or Telix) : you should unload it and reload it.
- Use the command ESS S and then ESS 1 (for COM1: !).
-
- - the TNC you are using is not compatible with TAPR prom 1.1.5
- or higher.
- => change your TNC or modify the CONFIG.TNC file.
