F110 – J1 Input (Time Code, TIET)
Or, if the TIET option is available, first put the time code input on standby (example):
F110 IRIG A STANDBY 50 DC POSITIVE 1234 US SYNC GEN 1 FRAME<CR>
And then configure TIET (example):
F110 TIET 100K POSITIVE<CR>
The XL-GPS responds:
OK<CR><LF>
Note: Note: If the TIET is configured, the timestamp(s) of the rising edge of the J1input sig-
nal will be displayed each second. Up to 100 time stamps can be spooled.
To obtain TIET measurement from J1, enter:
F110 TIET TIME<CR>
The XL-GPS responds:
OK<CR><LF>
.xxxxxxxxx<CR><LF>
(Time Interval (display continues until function termination with Ctrl+C)
Or, (example):
F110 TIET EVENT<CR>
The XL-GPS responds:
OK<CR><LF>
ddd:hh:mm:ss.xxxxxxxxx<CR><LF>
(Event Timing display continues until function termination with Ctrl+C)
For an IRIG Time Code with the IEEE 1344 extensions, enter F110<CR> to request the J1
Input Configuration, and the port will respond with the ASCII character string:
F110<SP><Code><SP><Source><SP><Impedance><SP><SP><Sign><SP>
<Delay><SP><Mode><SP><Bypass><LT>
where:
F = ASCII character F.
110 = function number.
<SP> = ASCII space character one or more
