5: Function Reference
XL-GPS responds in the following format:
F111<S><RATE><CR><LF>
Or
F111<S>PPO<S><START><S><STOP><CR><LF>
Where:
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

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.
