Product Overview:

Pulse-type data transmission ensures that all your information arrives “in one piece”! Each Start or Stop pulse from the timing source (gate, photocell, etc) is sent as a complete data packet, not just as an updated packet like other less-sophisticated systems. This feature virtually guarantees perfect performance

Sends simple timing impulses as well as data (scoreboards etc)

Two-channel capability, with optional RX-C10 10-channel expansion adapter
Output power: TX10- 10mW ; TX400- 400mW
Compatible with any half-duplex device using RS232 protocol
Built-in protection against false data
Built-in signal optimizer allows the user to tune the system to the optimum frequency using its unique LED and tone-based signal tuner.

Available in both short and long-haul versions: Short-range TED-TX 10 works up to approx. 1.5 km (1 mile); Long-range TED-TX 400 works up to approx. 5 km (3 miles). We have successfully tested these systems to far greater distances.
