To calculate what the setting should be, multiply the delay/foot by the length of the cable in feet. The
typical delays for the following cable types are:
RG-58 – approximately 1.4 ns/foot
RG-59 – approximately 1.24 ns/foot
Command Line
To display the current distribution cable delay, enter:
F52<CR>
The XL-GPS responds using the following format:
F52<SEP><SIGN><DELAY>ns<CR><LF>
where:
For example, to display the current distribution cable delay, enter:
F52<CR>
XL-GPS responds:
F52 +000000ns<CR><LF>
To set the distribution cable delay to 60 nS, enter:
F52 +000060nS<CR>
XL-GPS responds:
OK<CR><LF>
F = ASCII character F (f or F for input string).
52 = the function number.
<S> = one or more space characters.
<SIGN> = either + or –
<D> = 1 to 9 digit delay from +999999 nS to –999999 nS
ns = nanoseconds (ns or NS for input string)
<CR> = carriage return character
<LF> = line feed character
