Transmitting GAZ data from software using TED TX-RX

The only safe way to do this is using the "data transmission direct" option. (section 5.5 of manual) The only problem is that this eats batteries. We have made a wiring harness that works real well for this application. The data comes from the PC serial port (pin 3 signal, pin 5 grd, DB9) The data enters the TED TX on pin 6 of the DIN. Pin 2 and 3 are jumped together to force continous data transmission. Pin 4 and 3 are then "y" to a NLG13 power supply. This way the TED is powered by AC, the data is input and it is all done cleanly at the DIN plug. The data outputs from the RX receiver on Pin 6 of the DIN. Pin 4 is connected to the GAZ 12v + power and Pin 3 is ground. The GAZ end of the cable uses the 4 pole Amphenol connector. This way the RX is powered by the GAZ. Both the TX and RX have the rotary dial furthest from the metal bar (12 in manual) set to position 6. You can then jump the signal for a local GAZ out of the TX transmitter. Yellow banana for signal, black for ground. Set up the wireless first and get it tested. Then introduce the local display. The LED lamps on the TX and RX should remain solid green while this setting is used.

Actually, if you use any Broder's software you can set the TED's to program 1 for gaz data and everything works fine. We have used this as our primary way of using the displays wireless for many years with no problems. It is also very kind on batteries, typical 8-10 hours using dual courses, racers every 15-20 seconds and counting run times.

When using Geoff's software, you will have to use the Direct Transmission options.
For this past race weekend we needed to switch from GS to SL after the second day. This moved our finish line up the hill. We do have a small timing cablin at the SL finish but what a pain to move all of the gear. This was the perfect time to run the display with the TED. All of the jumper din/amp conecters were built and the TX was powered by a power supply to the DIN plug. The RX was supplied by the DIN/AMP connector to the boards and the boards were powered by a 12v deep cycle car batterey to another amp connector. We did not have an annoucer at the finish but the posting board had no trouble reading the displays and keeping up. No dead batteries and and no anoying rs-232 noise on the headsets.
