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. 5. The AXlink connector can also be used for RS-232 communications.

FIG. 5 AXB-IRS4 rear panel connectors
Do not connect power to the AXB-IRS4 until the wiring is complete. 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 | Maximum Wiring Length |
| |
18 AWG | 938.97 feet (286.19 m) |
| |
20 AWG | 594.06 feet (181.07 m) |
| |
22 AWG | 370.37 feet (112.89 m) |
| |
24 AWG | 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.
Preparing/connecting captive wires
1.Strip 0.25 inch of wire insulation off all wires.
2.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.
