Product Information 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.
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. Battery Lithium battery backup for stored control commands Enclosure type Metal with black textured finish Weight 1.12 lbs (508 grams) Dimensions 1.51" x 5.55" x 5.
Configuration and Installation 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. When you set the first device number on the DEVICE DIP switch, the AXB-IRS4 automatically assigns the next three device numbers.
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.
Configuration and Installation Setting the Internal Jumpers (E1 and E2) for AXlink or RS-232 Communication Internal jumpers are located on the circuit card inside the AXB-IRS4 enclosure. You will need a Phillips-head screwdriver to open the enclosure. Static electricity can damage electronic circuitry. Before removing the AXB-IRS4 circuit card from the enclosure, discharge any accumulated static electricity from your body and the screwdriver by touching a properly grounded metal object.

Configuration and Installation Using AXlink for data and power Connect the Central Controller's AXlink connector to the AXlink/RS-232 connector, on the rear panel of the AXB-IRS4, for data and 12 VDC power, as shown in FIG. 6. 12 VDC PWR connector on AXB-IRS4 PWR (+) GND (-) no connection PWR(+) AXlink/RS232 connector on AXB-IRS4 PWR AXP/TX AXP AXM/RX AXM GND (-) GND Axcess Control System FIG.
Configuration and Installation FIG. 8 shows the AXlink/RS-232, DB-9, and power supply wiring diagram. For some applications, you may need to strap pins 7 (request to send) and 8 (clear to send) together depending on the PC (as shown in the illustration). 12 VDC PWR connector on AXB-CAM PWR (+) GND (-) 12 VDC power supply PWR(+) AXlink/RS232 connector on AXB-CAM 2 (RXD) 3 (TXD) AXP/TX AXM/RX 5 (GND) GND (-) DB-9 connector (male) FIG.
Configuration and Installation Connecting an IR device IR devices connect to the AXB-IRS4 with an IR device cable. The cables supplied with the AXBIRS4 are designed to accommodate the IR devices in your system. IR cables have a two-pin connector on one end that plugs into the AXB-IRS4, and the other end has a device-specific interface adapter such as an IR emitter. Connect IR devices to the AXB-IRS4 as shown in FIG. 10. GND IR/Serial connector on AXB-IRS4 IR IR emitter GND IR device SER FIG.
Configuration and Installation Contact your AMX dealer before you replace the lithium battery and verify that they have a current copy of the AXCESS program for your AXB-IRS4. This will avoid any inadvertent loss of data or a service outage. You will need a flat-blade tool (non-conducting) that can be slipped under the lithium battery to pry it up and out of the socket. Static electricity can damage electronic circuitry.
Programming Programming Channel Setting Commands The AXB-IRS4 channel settings listed in the following table set IR output channels. The AXBIRS4 can process up to two IR or serial device channel setting commands simultaneously. If more than two device commands are sent simultaneously, only the first two devices receive the commands. The AXB-IRS4 can also be controlled with older SX-DCU+ RS-232 protocols. Channel Setting Commands Channel Description 1-252 Channel assignment for IR output.
Programming Send Commands (Cont.) Command Description 'CH',channel number Transmit the IR pulses that select 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 number. If the channel is greater or equal to 100, the IR Function Number (FN) 127 is generated for the one-hundredth digit.
Programming Send Commands (Cont.) Command Description "'SP',code" Transmit IR code pulses. Pulse time is set by the CTON and CTOF commands. Variable: code = 1-252 Example: SEND_COMMAND 1,"'SP',2" Transmits a pulse out for command number 2 to device 1. XCHM Changes the IR output pattern for the XCH command. Syntax: SEND_COMMAND ,'XCH-' Variable: Mode = 0-4 Example: SEND_COMMAND IR_1,'XCH 3' Sets the IR_1 device's extended channel command to mode 3.
Programming Send Commands (Cont.) Command Description XCH Transmit the IR code in the format set with the XCHM mode command. Syntax: SEND_COMMAND ,'XCH ' Variable: = 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.
Programming RS-232 Protocol Commands (IR Output - Cont.) Command Description ON[Dev,Chan] Start IR output on the designated device and channel. Variable: Dev = 1-4, Chan = 1-252 Example: ON[1,11] Starts device 1 and transmits command number 11. SP[Dev,Chan] Transmit single IR code pulse. This command will pulse the actual IR code. Pulse time is set by the CTON and CTOF commands. Variable: Dev = 1-4, Chan = 1-252 Example: SP[1,2] Transmits command number 2 pulses to device 1.
Programming RS-232 Protocol Commands (Miscellaneous) RS-232 Protocol Commands (Miscellaneous) Command Description ECHO OFF Disable the terminal character's echo function. ECHO ON Enable the terminal character's echo function. HELP Display the on-line help menu. MEM Display the current amount of available memory. VER Display the current software version of the AXB-IRS4. ZAP!(Dev) Clear the specified device's IR data, and re-initialize CTON CTOF to their default values.
