3-201 SERIAL FUNCTION F01 - TIME ZONE ENTRY/REQUEST
Use Serial Function F01 to select or determine the time zone offset. NOTE: Function 01 will provide
time zone offset only when the XL-DC is in LOCAL or STANDARD time mode (refer to Function 69).
To request the offset, send F01<CR> to the Serial Port. The port will respond with the following
character string:
F01<SEP><SIGN><HH>:<MM><LT>
where:
F = ASCII character F
01 = function number
<SEP> = one or more separator characters: either space, comma or tab.
<SIGN> = either no character or + for positive offsets or - for negative
offsets
<HH> = one - or two-digit hours offset from +12 to -12 hours
: = ASCII character for a colon
<MM> = two-digit minutes offset
<LT> = line terminator, either a carriage return and line feed for output strings or
a carriage return only for input strings
Sample request: F01<CR>
Response: -4:30<CR><LF>
To set the time zone offset, send a character string with the following format:
Sample entry: F01 -8:00<CR>
Response: OK<CR><LF>
Sample request: F01<CR>
Response: -8:00<CR><LF>
3-202 SERIAL FUNCTION F02 - 12/24 HOUR FORMAT ENTRY/REQUEST
Use Serial Function F02 to request or set the time display format. To determine the format, send
F02<CR> to the Serial Port. The port will respond with the following character string:
F02<SEP><HH><LT>
where:
F = ASCII character F
02 = function number
<SEP> = one or more separator characters: either space, comma or tab
<HH> = 12 or 24
<LT> = line terminator, either a carriage return and line feed for output strings or
a carriage return only for input strings
