Additional Interface Connections
Two additional outputs are provided on TB1 for custom applications: AC
power failure alarm, and the transceiver's Received Signal Strength Indication
(RSSI).
AC Alarm —Pin 12
H = AC Present—Approximately 11 Vdc through a 1 K
resistor
L = AC Failure—Ground through a 1 K resistor
Received Signal Strength Indicator (RSSI)—Pin 11
Same as transceiver's RSSI output. It pr o vides a DC volt a ge proportional to the
received signal strength. The range is approximately zero to five volts DC
through a 10K current limiting resistor. Refer to the transceiver manual for
additional RSSI information.
