The above format means that days are deleted, the first separator is a vertical bar and all other
characters are enabled and assume their default values.
When entering a new format string the character after "F11" is required but is ignored. To enter a "null"
format string send "F11" followed by a space, followed by a carriage return.
Sample entry: F11 <CR>
Response: OK<CR>
F08 string output: <SOH>DDD:HH:MM:SSQ<CR><LF>
F09 string output: <SOH>DDD:HH:MM:SS.mmmQ<CR><LF>
The above format means that all characters and separators are enabled and assume their default
values.
If the current format string is "null", F11 will return a space character followed by a carriage return.
Sample entry: F11<CR>
Response: F11 <CR>
The format string below explicitly enables all characters and has the same effect as a "null" format
string:
Sample entry: F11 DDD:HH:MM:SS.mmmQ<CR>
Response: OK<CR>
F08 string output: <SOH>DDD:HH:MM:SSQ<CR><LF>
F09 string output: <SOH>DDD:HH:MM:SS.mmmQ<CR><LF>

3-213 SERIAL FUNCTION F13 - WORST-CASE TIME ERROR REQUEST
Use Serial Function F13 to request the estimated worst-case time error due to oscillator drift during
periods when satellites are not being tracked. The worst-case time error while tracking satellites is
always 00.000000200 seconds. Time error begins to accumulate when the receiver loses contact with
the satellite signal. The XL-DC calculates the worst-case time error based on the stability of the time
base in use, either the internal or optional external oscillator (refer to Function 14), and the time
elapsed since loss of lock. The Serial Port will report this calculated error when it receives the string
F13<CR>, and responds with the following ASCII character string:
F13<SP><ERROR><CR><LF>
where:
F = ASCII character F
13 = function number
<SP> = ASCII space character
<ERROR> = calculated worst-case error in seconds
<CR> = carriage return character
<LF> = line feed character
