Command Line
For example, to initiate Continuous Time once-per-second, enter
F8<CR>
The XL-GPS replies:
199:11:19:30<CR><LF>
199:11:19:31<CR><LF>
199:11:19:32<CR><LF>
To stop Continuous Time Once-Per-Second, press Ctrl-C on your keyboard to stop it.
F9 – Time On Request
Note: This function is available through the command line interface only – it is not available through the
keypad.
Use function F9 to record the exact time the XL-GPS receives a request from the user.
Enter the command “F9<CR>” to prepare the XL-GPS for the user’s request. At the desired moment,
send the request to the XL-GPS by entering an upper case “T”. The XL-GPS saves the current time-of-
day, accurate to within 1ms, to a buffer, and then outputs it to the command line interface. The XL-GPS
will continue to provide the time-of-day each time it receives a “T” until F9 is cancelled. To cancel this
function, enter Ctrl-C on your keyboard. The command line disregards any input other than SHIFT-T until
it receives a Ctrl-C command.
The time-of-day output is only available on the port, network or serial, that was used to give the F9
command.
