Where:
Sample request:
F111<CR>
The XL-GPS displays a fixed 10 PPS rate output (example):
F111 RATE 10PPS<CR><LF>
. Or, displays the PPO settings (example):
F111 PPO 120:22:56:12.000000 120:22:56:12.000003<CR><LF>
Setting the J2 Output Configuration
To set the J2 Output Configuration, send a character string with the previously defined F111 entry format
to the Serial/Network port. Only valid values are accepted. The J2 Output Configuration can be set to
specify one of several predetermined rates, a single PPO pulse outputs, and repetitive PPO pulse
outputs. The following sections provide examples (and some explanations) for each.
Predetermined RATE output
For example, to produce a fixed 100 kPPS rate output, enter:
F111 RATE 100KPPS<CR>
XL-GPS responds:
F
= ASCII character F
111
= Function number
PPO
= ASCII character string "PPO"
<S>
= ASCII space character one or more
<RATE>
= Output rate or type, RATE 1 PPS, RATE 10 PPS, RATE 100 PPS, RATE 1 kPPS, RATE
10 kPPS, RATE 100 kPPS, RATE 1 MPPS, RATE 5 MPPS, RATE 10 MPPS
<START> & <STOP>
= Time-of-year with microsecond resolution in the format of yyy:hh:mm:ss.uuuuuu.
Range: [001:00:00:00.000000, 366:23:59:59.999999] Note: Wildcard character: 'X' or
'x' can also be entered. See the section regarding time string with wildcard character.
Colon separators (“:”) are required
<CR><LF>
= Line terminator: a carriage return and line feed for output strings, or a carriage return
for input strings
