X1
= port number (01 = rear host port, 03 = slave switcher port, 04 = front panel host port, 05 = projector control port, 06 = IR/Serial port A,... 09 = port D).
X17
= time in tens of ms to wait until receipt of the first response character before terminating the command (default = 10 = 100 ms, max. = 32767).
X20
= time in tens of ms to wait between characters being received via a serial port before terminating the current command or receive operation
(default = 2 = 20 ms, max. = 32767).
X21
= #L or #D. The letter parameter is case sensitive (requires capital D or capital L).
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 # can be from 0 to 00255, default = the byte count. A 3-byte length = 3L. A delimiter of ASCII 0A = 10D. The response includes leading zeros
X2
= command data section = {data} = data that will be directed to a specified port. When using either Telnet or a Web browser, be sure to convert nonalphanumeric characters
in

to hex numbers. Data must be hex encoded if non-alphanumeric.
