AXB-IRS4 IR/Serial Interface, 4 Ports

Overview

The AXB-IRS4 (FG5914) operates as an AxLink bus device or as an independent RS-232-

to-IR interface. The four IR ports can be set up for IR or wired serial operation. Any two ports

can send commands at the same time; internal firmware stacks any remaining IR pulses and

executes them in sequence. Each unit emulates four AxLink devices.

Specifications

Configuration and Installation

Setting the DIP Switches

Note: Use the DIPSwitch 2.0 application available for free download from AMX to quickly

figure out DIP Switch settings for all types of DIP Switches.

Setting the DEVICE DIP Switch

Set the device number on DEVICE DIP switch, located on the front of the AXB-IRS4. The

device can be 1 of the 255 devices in an Axcess control system. The device number must

match the device assignment in the Axcess program. Device numbers are assigned into the

following three segments:

• Cards 1 through 95

• Boxes 96 through 127

• Panels 128 through 255

Set the device number by setting the device DIP switches. The device number is the total of

all of the switches in the ON position, and take effect by cycling the power.

Setting the Carrier/BAUD DIP Switch

The CARRIER/BAUD DIP switch sets the carrier signals and baud rates for the AXB-IRS4.

FIG. 2 shows the DIP switch positions.

Positions 1-4: Carrier Signal Enable/Disable

DIP Switch positions 1-4 on the CARRIER/BAUD DIP switch determine wether the

AXB-IRS4 transmits carrier signals along with the IR equipment codes.

• If DIP switch positions 1 through 4 are set to the up position, the carrier signal is

enabled and the AXB-IRS4 transmits IR equipment codes at device-specific signal fre-

quencies.

• If DIP switch positions 1 through 4 are set to NC (down), the carrier signal is disabled

and the IR equipment codes transmit without the carrier signal.

Set the DIP switch positions 1 through 4 when you determine the port assignments and

signal requirements for the IR and serial devices in your system.

Position 5: RS-232/PCTouch Mode

DIP switch position 5 on the CARRIER/BAUD DIP switch sets either RS-232 or PCTouch

mode.

If you enable PCTouch mode, the AXB-IRS4 will only respond to PCTouch (PCCOM)

command protocol. If you enable RS-232 mode, the AXB-IRS4 will respond to the standard

AXB-IRS4 control protocol, PCCOM control protocol, and SX-DCU+ control protocol.

You can also use RS-232 mode to download codes to the AXB-IRS4 with the IRLIB software

program.

• Position 5 (up): RS-232 mode enabled.

• Position 5 (down): PCTouch mode enabled.

Note: Refer to the PCTouch/ PCDesign Instruction Manual for detailed PCTouch program

information.

Positions 6-8: Baud Rate Setting

DIP switch positions 6-8 on the CARRIER/BAUD DIP switch sets the baud rate for RS232

communications. Communication settings are 1 stop bit, 8 data bits, and no parity. The

following table shows the baud rate settings on the CARRIER/BAUD DIP switch.

Setting Internal Jumpers E1 and E2 for Communication Mode

Internal jumpers are located on the circuit card inside the AXB-IRS4 enclosure. You will need

a Phillips-head screwdriver to open the enclosure..

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

under Replacing the Lithium Battery section. 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 Central Controller sends the proper control commands to

the correct device. See Setting the Device DIP Switch 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 Setting the Carrier/BAUD DIP switch 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

communications.

• 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 Wiring the AXB-IRS4 for details.

PWR connector 2-pin captive wire connector connects an external 12 VDC power

supply to the AXB-IRS4. An external power supply should be used

when the distance between the AXB-IRS4 and control system

exceeds the wiring guidelines described under Wiring Guidelines.

Battery Lithium battery backup for stored control commands
