Baud Rate
Select
Command:
Response:
Status:
Response:
Where: xxxx = 300 to 19200, in standard settings of 300, 600,
1200, 2400, 4800, 9600 (default), and 19200.
RS-232
Parity
Select
Command:
Response:
Status:
Response:
Where: xx = OD (odd), EV (even) (default), or NO (none) (8-
bit).
Reference
Freq Adjust
Command:
Response:
Status:
Response:
Where: nnn = DAC setting 0 to 255.
Where: nnn = Current DAC setting.
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 or OFF. Default = ON, enable monitor.
Allows user to disable LNA fault.
External
Fault
Enable
Command:
Response:
Status:
Response:
Where: xxx = ON or OFF. Default = ON, enable monitor.
This command is used to enable an external fault signal from a
customer-supplied external high-power amplifier. The external
source interfaces with the RFT-1200 at connector J6, pin M.
This signal must be a ground for an 'Okay' condition and 'Open'
for a faulted condition.
This input is 'OR'ed with the internal high-power amplifier
signal to produce an uplink fault, thus allowing the use of both
internal and external high-power amplifiers.
LNA Power
Enable
Command:
Response:
Status:
Response:
Where: xxx = ON (default) 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-503L switch.
(INDEP TX and RX switch independently on fault to backup
terminal. DEP switches both TX and RX on fault to backup
terminal.)
