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.

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. Connector pins 2, 3, and 5 are used for data and ground. The following table lists the DB-9 wiring pinouts.
