AXB-IRS4 IR/Serial Interface (4 Ports) 5 Configuration and Installation Wiring the AXB-IRS4 The serial, IR, AXlink, and power supply connectors are located on the rear panel of the AXB-IRS4 as shown in FIG. The AXlink connector can also be used for RS-232 communications.

If you are using power from AXlink, disconnect the wiring from the Card-Frame before wiring the AXB-IRS4. If you are using an optional 12 VDC power supply, apply power to the AXB-IRS4 only when the installation is complete. Wiring Guidelines The AXB-IRS4 requires 12 VDC power to operate properly. The power can be supplied by the AMX system's AXlink cable or with an optional 12 VDC power supply. The maximum wiring distance between the control system and AXB-IRS4 is determined by power consumption, supplied voltage, and the wire gauge used for the cable. The following table lists wire sizes and the maximum lengths allowable between the AXB-IRS4 and control system. The maximum wiring lengths for using AXlink power are based on a minimum of 13. 5 volts available at the control system's power supply. Wiring Guidelines at 125 mA Wire Size 18 AWG 20 AWG 22 AWG 24 AWG Maximum Wiring Length 938. 97 feet (286. 19 m) 594. 06 feet (181. 07 m) 370. 37 feet (112. 89 m) 233. 46 feet (71. 16 m) If the AXB-IRS4 is installed farther away from the control system than recommended in the Wiring Guidelines table, connect a 12 VDC power supply to the 2-pin 12 VDC PWR connector on the rear panel. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section. Do not tighten the screws excessively; doing so may strip the threads and damage the connector. 6 AXB-IRS4 IR/Serial Interface (4 Ports) 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 (-) PWR(+) no connection PWR AXP AXM GND AXlink/RS232 connector on AXB-IRS4 AXP/TX AXM/RX GND (-) Axcess Control System FIG. 6 AXlink data and power wiring diagram Using AXlink for data and a 12 VDC power supply Connect the Central Controller's AXlink connector to the AXlink/RS-232 connector, on the rear panel of the AXB-IRS4, and the optional 12 VDC power supply, as shown in FIG. 7. 12 VDC PWR connector on AXB-IRS4 PWR (+) GND (-) PWR(+) 12 VDC power supply PWR AXP AXM GND AXlink/RS232 connector on AXB-IRS4 AXP/TX AXM/RX GND (-) Axcess Control System FIG. 7 AXlink and optional 12 VDC power supply wiring diagram Use the 12 VDC power supply when the distance between the AMX system and AXB-IRS4 exceeds the limits described in the Wiring Guidelines at 125 mA table on page 6. Make sure to connect only the GND wire on the AXlink/RS-232 connector when using a 12 VDC power supply. Do not connect the PWR wire to the AXlink connector's PWR opening. Using the AXlink-to-DB-9 connector cable for a PC system To use a PC, set the internal jumpers for RS-232 communication mode and the DEVICE DIP switch positions 1 - 8 off (down). The AXlink/RS-232 connector, on the back of the AXB-IRS4, can be connected to a PC system using a DB-9 connector cable.

The following RS-232 figures are grouped together by IR output, channel pulse time, and carrier commands. RS-232 Protocol Commands (IR Output) RS-232 Protocol Commands (IR Output) Command CH[Dev, Chan] Description Transmit IR pulses to the designated device that selects the proper channel.
