Reply to "Questions about TED transmitters"

There is always the possibility that your units have become out of tune/ calibration. I know that they are from very early in the production run. You can find out what year they were made by looking next to the battery compartment. the year ; 97, 98 etc is the first part of the serial number, month, day too.

The cable from the receiver to the S4 has 4 wires, pin 3 grouind, pin 4 power, pin 1 start, pin 2 finish. A button or photocell input on the transmitter in the banana plugs, green/signal, black/ground should send a start pulse to the S4 if it is on Program 0. A photocell connected to the transmitter din socket with the red 001.10
cable should send a finish. A cable (002.10) with pin 1 active instead of 2 would send a start as well.

The receiver should be able to receive a nice solid test tone when the button on the transmitter is pressed. Nothing will happen if the test tone is not checked and verified that it is solid.

We have several loaner units in stock for emergencies. Normally we send the units back for upgrading. It takes about 3 weeks.
