Use the SUPPRESS command to suppress all F73 faults from triggering alarms for a specified duration
after the XL-GPS power is turned on. To check the SUPPRESS status, enter:
F73<SP>SUPPRESS<CR>
The XL-GPS responds in the following format:
F73<SP>POWER-ON<SEP>MINOR<SEP>ALARM<SEP>SUPPRESS<SEP> <seconds><CR><LF>
where:
To set the SUPPRESS enter a command using the following format:
F73<SP>SUPPRESS<SEP><seconds><CR>
The seconds can be set to any value from 0 to 86400. The XL-GPS responds:
OK<CR><LF>
F90 – Code Output Configuration
Use function F90 to select AM or DC modulation of the IRIG-B time code on the following outputs:
• the CODE output on the Main CPU card
• the J1 through J3 outputs on the Expansion Module
The factory configuration for F90 is IRIG-B AM.
Note : For the Expansion Module, the IRIG-B modulation type is controlled by a hardware jumper setting
and by F90. The four “JP2 - Output Header” jumpers located on the Expansion Module individually set
the modulation types on J1, J2, J3, and J4. The modulation is AM when the jumper is set to AM,
regardless of the software setting in F90
. If the jumper is set to DC, F90 can be used set the output to
either AM or DC. In other words, the F90 setting applies to all outputs, unless the jumper setting is AM.
