Comtech EF Data XTRT-400C Operation And Installation Manual page 137

Command Byte: 'O'
Function: Sets a Reflected RF trip point. If reflected power exceeds the set point, an alarm or fault is generated, as
specified by the user. (Note: A hardware Reflected RF Trip Point is pre-set at the factory. You cannot adjust the
hardware trip point by changing the software trip point). By default, the trip point is not enabled until the "Enable RF
Limits" command ('R') is processed.
Parameter:
"AXXXX" to set an Alarm trip point,
"FXXXX" to set a Fault trip point, "D" to disable.
XXXX is the desired trip point in Watts.
Command Byte: 'P'
Function: Miscellaneous Setup
Parameter "Cx" to set Configuration Mode.
x is the redundancy mode you wish to operate.
0 — is single thread no waveguide switch.
1 — is redundant system with one waveguide switch (1:1 configuration.)
2 — is power combined system with two waveguide switches (1+1 configuration.)
3 — is redundant system with a load switch on the output (1:1 w/load.)
4 — Reserved
5 — VPC System
S — Summary Fault Test
Parameter "Ex"
Nxxx.xxx.xxx.xxx = netmask.
Ox = Set operating mode: 0 = DHCP, 1 = Static IP
Ixxx.xxx.xxx.xxx = IP address
Rxxx.xxx.xxx.xxx = Set router IP address.
S = Restart Ethernet
example: PEO0 - sets amplifier to DHCP Mode.
example: PEI - PEI 250.10.7.170 sets unit IP address to 250.010.007.170
Parameter: "Xn"
X = Amplifier High Voltage state at power ON.
n = Power ON state: 0 = NORMAL (the last state before Power OFF); 1 = OFF; 2 = ON.
