	RSX@

N* X1& * X2) * X2! 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.

NFor 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: E05*4*7*3L RS }<data> W05%2A4%2A7%2A3L RS<data>

response from command ]

NThe data string (X@) in this RS command is limited to 200 bytes.

X! = 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.

ASCII to Decimal Conversion Table

To find the decimal equivalent of the ASCII character, add the row heading and column heading numbers together.

	0	1	2	3	4	5	6	7	8	9

20								Esc
30			space	!	“	#	$	%	&	’

LF = line feed

CR = carriage return (})

Esc = escape Del = delete

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.
