Command:
Response:
Status:
Response:
Where: xxxxx = 300 to 19200, in standard settings of 300,
600, 1200, 2400, 4800, 9600 (default), and 19200 kbit/s.
RS-232-C
Parity
Select
Command:
Response:
Status:
Response:
Where: xx = OD (odd), EV (even, the default), or NO (none,
8 bit).
Reference
Freq Adjust
Command:
Response:
Status:
Response:
Where: nnn = Current DAC setting from 0 to 255.
LNA
Calibration
Command:
Response:
Performs a current windowing calibration on the LNA.
Note: This is only done once during the initial installation.
LNA Fault
Enable
Command:
Response:
Status:
Response:
Where: xxx = ON (default = on, enable monitor) or OFF.
External
Fault
Enable
Command:
Response:
Status:
Response:
Where: xxx = ON (default = on, enable power) or OFF.
This command is used to replace the internal HPA fault signal
with a customer-supplied fault signal from an external HPA as
the source of the HPA fault in the 'FS_' command.
The external source interfaces with the RF terminal at
connector J6, pin M. This signal must be an OPEN/GND
signal, with OPEN defined as the fault condition.
LNA Power
Enable
Command:
Response:
Status:
Response:
Where: xxx = ON (default = on, enable power) or OFF.
This command is used to route the LNA DC power to the coax
cable or to remote it.
'ON' means DC power will be available on the center
conductor of the coax cable to the LNA. 'OFF' means DC
power will be removed.
Under both conditions, LNA DC power will always be available
on connector J6, pin K.
Note: This command is only available with M&C boards Rev.
C and newer.
Redundant
Switch
Mode
Command:
Response:
Status:
Response:
Where: xxxxx = INDEP (the default) or DEP.
Note: For use in redundant system only with RSU-503 switch.
(INDEP TX and RX switch independently on fault to backup
terminal. DEP switches both TX and RX on fault to backup
terminal.)
