AMX AXB-IRS4 instruction manual RS-232 Protocol Commands IR Output

Programming

Send Commands (Cont.)

Command	Description
XCH <Channel>	Transmit the IR code in the format set with the XCHM mode command.
	Syntax:
	SEND_COMMAND <DEV>,'XCH <Channel>'
	Variable:
	<Channel> = 0 through 999

RS-232 Protocol Commands

The RS-232 protocol commands listed in the following tables send control signals from an RS-232 device to the AXB-IRS4. The following RS-232 figures are grouped together by IR output, channel pulse time, and carrier commands.

RS-232 Protocol Commands (IR Output)

RS-232 Protocol Commands (IR Output)

Command	Description
CH[Dev,Chan]	Transmit IR pulses to the designated device that selects the proper channel.
	Enter all channel numbers below 100 as two digits. For example, enter channel
	1 as 01. If the IR code for ENTER (#21) is loaded, an ENTER follows the num-
	ber. If the channel is greater or equal to 100, IR FN 127 is generated for the
	one-hundredth digit.
	Variable:
	Dev = 1-4, Chan = 1-199
	Example:
	CH[1,18]
	The AXB-IRS4 performs the following:
	• Transmits IR pulses for 1 (IR code 11) for the time set by CTON.
	• Waits for the time set by CTOF.
	• Transmits IR pulses for the IR code for 8 (IR code 18) for the time set by
	CTON.
	• Waits for the time set by CTOF. If the IR code for ENTER (IR code 21) is
	programmed, steps 5 and 6 are performed.
	• Transmits IR pulses for ENTER (IR code 21) for the time set by CTON.
	• Waits for the time set by CTOF.
CP(Dev,Chan)	Transmit IR code pulses and clear all commands in the buffer. This command
	pulses the actual IR code. Pulse time is set by the CTON and CTOF com-
	mands.
	Variable:
	Dev = 1-4, Chan = 1-252
	Example:
	CP[1,2]
	Clears pending commands and pulses command number 2.
OFF[Dev,Chan]	Stop IR output on the designated device and channel.
	Variable:
	Dev = 1-4, Chan = 1-252
	Example:
	OFF[1,11]
	Stops device 1 from transmitting command number 11.
