where:
Note: Parity - NONE is only available/valid when Data Bits is set to 8.
For example, to display the serial port settings, send:
F4<CR>
The XLi responds:
F4 232 9600 8 none 1<CR><LF>
To set the serial port settings, send:
F4 422 9600 7 even 1<CR>
XLi responds:
OK<CR><LF>
F5 – Time-Quality Setup
Use function F5 to enable/disable time quality reporting, and to set the thresholds of the four time-quality
flags.
How time quality reporting works in the XLi: When a reference source becomes unavailable, the XLi
uses its own oscillator to keep track of time. Without the reference source, the XLi can no longer adjust,
or steer, the oscillator to remain synchronized with the reference source. The rate at which the oscillator
counts time is slightly faster or slower than the reference source. The resulting difference, time error,
accumulates over time.
F = ASCII character F.
04 = function number.
<S> = ASCII space character (one or more).
<SEP> = One or more separator characters: either space, comma or tab.
<RS> = Interface type, RS-232 or RS-422
<BR> = Baud Rate, with possible values 1200, 2400, 4800, 9600, or 19200
<DB> = Data Bits, with possible values 7 or 8
<P> = Parity, with possible values “even” or “odd” or “none”
<SB> = Stop Bits, with possible values 1 or 2.
<CR> = Carriage return character.
<LF> = Line feed character.
