= specific port number (01 – 99)
1 = rear host (Host Control RS-232 port)
2 = front panel Config port
3 = slaved switcher (MLS port)
4 = display port (Projector RS-232/IR)
5 = IR/Serial port A
6 = IR/Serial port B
7 = IR/Serial port C
X@
= command data section (< 200 bytes).
X1&
= time in tens of ms for the IPL T S unit
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 ms for the IPL T S 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&
is optional 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.
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

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
