Product Information

The AXB-IRS4 (FIG. 1) is an AXCESS bus device you can program to control up to four infrared (IR) or serial-controlled audiovisual devices such as televisions and video cassette recorders. The AXB-IRS4 can be controlled by an AMX AXCESS or AXCENT2 system, or independently with a personal computer (PC).

The AXB-IRS4 can be programmed to control a wide variety of AV equipment. If you change the IR or serial equipment in your system, you can easily reprogram the AXB-IRS4 with new control commands. This flexibility allows you to upgrade your system as advances are made in AV equipment.

Front panel components

AXlink LED	The AXlink LED blinks when there is AXlink or RS-232 communication activity
	or a memory error. If an AMX system controls the AXB-IRS4, the green AXlink
	LED indicates the following power and data activity, or memory errors:
	• One blink per second: Power is active and the AXlink is functional.
	• Full on: Power is active and AXlink communication is not functional.
	• Fast blink: There is a memory error. A memory error can be caused by a
	power-deficient battery. Follow the instructions in the Replacing the Lithium
	Battery section on page 9. If the error continues, contact AMX technical
	support for assistance.
	• If a PC system controls the AXB-IRS4, the green AXlink LED blinks when
	RS-232 data is received or transmitted.

DEVICE DIP switch	8-position DIP switch that sets the AXB-IRS4's device number so that the Cen-
	tral Controller sends the proper control commands to the correct device. See
	the Setting the Device DIP Switch section on page 3 for details.

CARRIER/BAUD DIP switch	8-position DIP switch that sets the carrier/No Carrier (NC) option on the AXB-
	IRS4 ports, and the data transmission speed. See the Setting the Carrier/
	BAUD DIP switch section on page 3 for details.

IR/Serial LEDs (1-4)	The red IR/SERIAL LEDs blink when the AXB-IRS4 transmits IR or serial data
	on ports 1 through 4.

Rear panel components

4 IR/Serial connectors	2-pin captive wire connector for each IR/serial port.

AXlink/RS232 connector	4-pin captive wire connector that supports AXlink or RS-232 data communica-
	tions.
	• If you have an AMX system, use an AXlink cable to connect to the control
	system.
	• If you have a PC, use a DB-9 or DB-25 RS-232 cable to connect to the PC.
	See the Wiring the AXB-IRS4section on page 6 for details.
