Additional description
Serial data port configuration and use
These commands apply to any port that uses RS-232 communication: both 1-way (output) and 2-way (bidirectional) RS-232 communication. Send data string
E X!
*
X1&
*
X2)
*
X2!
RS
} X@ X!
= specific port number
2 = Display RS-232/IR port
3 = MLS port
X@
= command data section (< 200 bytes).
X1&
= time in tens of ms for the MLC to wait
until receipt of the first response character before terminating the current receive operation (default = 10 = 100 ms, max. = 32767). The response includes leading zeros.
X2)
= time in tens of milliseconds (ms) for
the MLC to wait between characters being received via a serial port before terminating the current receive operation (default = 2 =
20 ms, max. = 32767). The response includes leading zeros. X2!
= #L or #D. The letter parameter is case
sensitive (requires a capital “D” or capital “L”). The response includes leading zeros. L = length of the message to be received. D = delimiter value. # = byte count (for L) or a single ASCII character expressed in decimal form (for D). Byte count # can be from 0 to 32767, default = 0. The ASCII decimal delimiter # value can be from 0 to 00255, default = the byte count.
Examples: A 3‑byte length = 3L. A delimiter of ASCII 0A = 10D.

is optional.
X1&
may be omitted only if
X2)
is also missing. If these three variables are not specified, the
default values are used. For this command,
X1&
and
X2)
must both a) equal zero and b) be nonzero, or c) both be omitted.
N
For Web encoding for
X@
, convert nonalphanumeric characters to hex numbers. A space (hex = 20) is encoded as %20.
A plus sign (hex = 2B) is encoded as %2B. Example:
E
05*4*7*3L RS

ASCII to Decimal Conversion Table
To find the decimal equivalent of the ASCII character, add the row heading and column heading numbers together.
LF = line feed CR = carriage return (
})
Esc = escape Del = delete
