A GND -RX/TX RX/TX Data
B -RX/TX RX/TX Data
C +RX/TX RX/TX Data
D CTS +RX/TX Clear to Send (see Note 1)
E RD/RX Receive Data
F RTS Ready to Send (see Note 1 )
G TD/TX Transmit Data
H DSR Data Set Ready
J GND Ground
K LNA_PWR Output, 10V for powering LNA (see Note 2)
L EXT_PWR Output voltage, 11V, to power RSU-503 and KP-10
M EXT FLT Input, logic 0 or 5V: 5V = FLT, 0V = normal (see Note 3)
N N/C
P SPARE N/C
R GND Ground
S SPARE N/C
T PWR MON EXT HPA PWR Level Monitor (Future)
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 DL_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)
b EXT_TEMP EXT HPA Temperature Monitor
c ENAB/DISAB EXT HPA RF Enable
Notes:
1. In EIA-232 mode, CTS is tied to RTS.
2. LNA can be powered from these pins instead of through the RF cable.
3. 5V is a floating level.
