To enable or disable the external oscillator, send a character string with the following format:
Sample entry: F07 OFF<CR> or F07 ON<CR>
Response: OK<CR><LF>
3-208 SERIAL FUNCTION F08 - CONTINUOUS TIME ONCE PER SECOND ENABLE
The Internal Trimble SVeeSix time will output once per second at the Serial Port prior to acquisition of
satellite signals. Time-of-year will output once per second after acquisition of satellite signals.
Character transmission is continuous with the end of the stop bit of one character coinciding with the
beginning of the start bit of the next character. The time output string format may be changed with
Serial Function F11. The default output string format is:
<SOH>DDD:HH:MM:SSQ<CR><LF>
where:
<SOH> = ASCII Start-of-Header character (HEX 01)
<CR> = ASCII Carriage Return character (HEX 0D)
<LF> = ASCII Line Feed character (HEX 0A)
DDD = day-of-year
HH = hours
MM = minutes
SS = seconds
mmm = milliseconds
: = colon separator
Q = time quality character
The time quality character may be a:
SPACE which indicates a worst-case error less than threshold 1
. which indicates a worst-case error greater than or equal to threshold 1
* which indicates a worst-case error greater than or equal to threshold 2
# which indicates a worst-case error greater than or equal to threshold 3
? which indicates a worst-case error greater than or equal to threshold 4
The time quality character prior to satellite signal acquisition will be "?". Refer to SERIAL FUNCTION
F13 - WORST-CASE-TIME ERROR REQUEST. The carriage return character <CR> start bit begins
on the second, +0 to +1 bit time or +1 ms, whichever is larger. Time will continue to output once per
second until the port receives a CTRL-C character (Hex 03). The port will ignore all other input until it
receives a CTRL-C.
