Additional description
Serial port conguration and use
These commands apply to any port that uses RS-232 communication: both 1-way (output) and 2-way (bidirectional) RS-232 communication.

= Specific port number (01-99):
Serial ports: IR/serial ports:
01 = COM1 port 09 = IR/serial port 1
02
= COM2 port 10 = IR/serial port 2
03
= COM3 port 11 = IR/serial port 3
04
= COM4 port 12 = IR/serial port 4
05
= COM5 port 13 = IR/serial port 5
06
= COM6 port 14 = IR/serial port 6
07
= COM7 port 15 = IR/serial port 7
08 = COM8 port 16 = IR/serial port 8
00 = reserved or all ports
X@
= command data section (< 200 bytes).
X1&
= time in tens of ms for the IPCP 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 IPCP 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 indicates the length of the message to be
received.
D indicates the delimiter value that ends the
response.
# = 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 = 0L.
For #L, # is a regular ASCII (character)
numeral. If the length is 50 bytes, # = 50.
For #D, # can be any character(s) or
number(s), but it is translated into decimal
format for use in the command.
Examples: A 3-byte message length = 3L.
A delimiter of $ would be entered as 36D
(36 is the decimal equivalent of the dollar
sign).
A delimiter of ASCII 0A = 10D (line feed).

X2!
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 or
b) be nonzero, or c) both be omitted.
NOTE: For web encoding for
X@
, convert non-alphanumeric 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

NOTE: The data string (
X@
) in this RS command is limited to 200 bytes.
NOTE: Use the ASCII to decimal table below to convert the delimiter character for
X2!
when using a delimiter (D).

ASCII to Decimal Conversion Table
To nd 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
