T ALOG TST Analog test voltage output
U UL_NC Uplink fault relay, connects to uplink COM with fault
V UL_COM Uplink fault relay, COMMON
W UL_NO Uplink fault relay, opens with fault
X DL_NC Downlink fault relay, connects to downlink COM with
fault
Y DL_COM Downlink fault relay, COMMON
Z DL_NO Downlink fault relay, opens with fault
a LNA PWR RTN Return for LNA Power (see Note 2 below)
b SPARE
c SPARE
Notes:
1. In RS-232 mode, CTS is tied to RTS (and vice versa).
2. LNA can be powered from these pinouts instead of up through the RF cable.
3. 5V is a floating level.
