AXB-IRS4 IR/Serial Interface (4 Ports)
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.
Specifications
AXB-IRS4 Specifications
Control Controls up to four IR or serial devices
Memory 28K bytes (total); stores up to 200 control commands in each port.
Power requirement 12 VDC
Power consumption 125 mA
Supported baud rates 300, 600, 1,200, 2,400, 4,800, 9,600, 19,200
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-IRS4 section on page 6 for details.

Configuration and Installation
Setting the Device DIP Switch
The 8-position DEVICE DIP switch sets the AXlink identification number for the AXB-CAM.
Make sure the device number matches the number assigned in the AXCESS software program.
Configuration and Installation
When you set the first device number on the
assigns the next three device numbers. For example, if you set the
DEVICE DIP switch, the AXB-IRS4 automatically
DEVICE DIP switch to 97
(1+32+64=97) as shown below, the AXB-IRS4 sets ports 1 through 4 as device numbers 97, 98, 99,
and 100.

Position 12345678
Value 1 2 4 8 16 32 64 128
To reset the AXB-IRS4 with a new DIP switch device number, disconnect and connect the AXlink
or 12 VDC power connector on the AXB-IRS4.
If the AXB-IRS4 is wired for RS-232 communication, set all eight DIP switch positions
to the off (up) position.
Setting the Carrier/BAUD DIP switch
The CARRIER/BAUD DIP switch sets the carrier signals and baud rates for the AXB-IRS4.
! DIP switch positions 1 through 4 set the carrier/NC signal option for ports 1 through 4.
! DIP switch position 5 is used for RS-232 or PCTouch mode.
! DIP switch positions 6 through 8 set the baud rate for RS-232 data communication.
FIG. 2 shows the DIP switch positions.
