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 Memory Power requirement Power consumption Supported baud rates 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 Central Controller sends the proper control commands to the correct device. See the Setting the Device DIP Switch section on page 3 for details. Controls up to four IR or serial devices 28K bytes (total); stores up to 200 control commands in each port. 12 VDC 125 mA 300, 600, 1,200, 2,400, 4,800, 9,600, 19,200 CARRIER/BAUD DIP switch 8-position DIP switch that sets the carrier/No Carrier (NC) option on the AXBIRS4 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) Rear panel components 4 IR/Serial connectors AXlink/RS232 connector 2-pin captive wire connector for each IR/serial port. 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 the Wiring the AXB-IRS4 section on page 6 for details. The red IR/SERIAL LEDs blink when the AXB-IRS4 transmits IR or serial data on ports 1 through 4. AXB-IRS4 IR/Serial Interface (4 Ports) 1 Product Information AXB-IRS4 Specifications (Cont.) 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 in the Wiring Guidelines section on page 6.

Make sure the device number matches the number assigned in the AXCESS software program. When you set the first device number on the DEVICE DIP switch, the AXB-IRS4 automatically assigns the next three device numbers. For example, if you set the 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. DEVICE 1 23 45 678 ON FIG. 1 DEVICE DIP switch, set to 97 The following table describes the values on the DEVICE DIP switch. Device DIP Switch Settings Position Value 1 1 2 2 3 4 4 8 5 16 6 32 7 64 8 128 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. CARRIER/BAUD 1 23 45 67 8 NC Baud rate settings RS232/PCTouch mode select Carrier signal enable/disable FIG. 2 CARRIER/BAUD DIP switch AXB-IRS4 IR/Serial Interface (4 Ports) 3 Configuration and Installation 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 frequencies. 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 RS232 mode to download ...
