Additional description
Serial data port confi
guration and use
These commands apply to any port that uses RS-232 communication: both 1-way (output) and 2-way (bidir
ectional) RS-232 communica
tion.

X1&
= time in tens of ms for the MLC to wait
until r
eceipt of the fi
rst r
esponse character
befor
e terminating the curr
ent r
eceive
operation (default = 10 = 100 ms, max. = 32767). The r
esponse includes leading zer
os.
X2)
= time in tens of ms for the MLC to
wait between characters being r
eceived via
a serial port befor
e terminating the curr
ent
receive operation (default = 2 = 20 ms, max. = 32767). The r
esponse includes
leading zer
os.
X2!
= #L
or #D. The letter parameter is case
sensitive (r
equir
es a capital “D” or capital
“L”). The r
esponse includes leading zer
os.
L =

eceived.
D =

elimiter value.
# = byte count (for L) or a single
ASCII
character expr
essed in decimal form (for D).
Byte count # can be fr
om 0 to 32767, default
= 0. The
ASCII decimal delimiter # value
can be fr
om 0 to 00255, default = the byte
count. Examples: A
3-byte length = 3L. A
delimiter of
ASCII 0A
= 10D.
