2.11 Program Input Fault Time-out

You can enable an automatic turn-off of the carrier in the event of program failure. To en-
able this option, see illustration 2-18 on page 2-16. The time between program failure and
carrier turn-off is set by a jumper (JP1) on the voltage regulator board (see page 6–14 for
board location). Jumper pins 1 and 2 (the two pins closest to the edge of the board) for a
delay of approximately 30 seconds; pins 3 and 4 for a 2–minute delay; pins 5 and 6 for a 4–
minute delay, and pins 7 and 8 for an 8– minute delay.

2.12 Remote I/O Connector

Remote control and remote metering of the transmitter is made possible through a 25–pin,
D-sub connector on the rear panel. (No connections are required for normal operation.)
