The XLi responds:
F2<S>D<HH><SEP>I<HH><CR><LF>
where:
For example, to display the current hour format, send:
F2<CR>
The XLi responds:
F2 D24 I24<CR><LF>
To set the hour format, send:
F2 D12 I24<CR>
XLi responds:
OK<CR><LF>
F3 – Time & Date
Use function F3 to set the XLi system clock’s time and date. If the XLi is using GPS as its primary
reference source, setting F3 manually is unnecessary. Following startup, the XLi synchronizes its time
and date to the GPS reference source
1
. If the XLi doesn’t have GPS as its primary reference source, use
F3 to set the time for the IEEE 1588 option card.
F3 prompts the user for the Time Mode, the Date in mm/dd/yyyy format, and the Time in hh:mm:ss
format. The hours in hh:mm:ss should be given using 24-hour notation (e.g., 6 pm = 18:00).
F = ASCII character F.
02 = Function number.
<S> = ASCII space character (one or more).
D = ASCII character for Display format.
<HH> = 12 or 24.
I = ASCII character for IRIG format
<CR> = Carriage return character.
<LF> = Line feed character.
