AXB-IRS4 IR/Serial Interface (4 Ports)
Connecting an IR device
IR devices connect to the AXB-IRS4 with an IR device cable. The cables supplied with the AXB-
IRS4 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.
Connecting a serial device
Serial devices connect to the AXB-IRS4 with a serial device cable. The cables supplied with the
AXB-IRS4 are designed to accommodate the serial devices in your system. Serial 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 a control plug.
Connect serial devices to the AXB-IRS4 as shown in FIG. 11. Each serial device requires a model-
specific cable. Make sure to match each serial device with the appropriate cable.
Replacing the Lithium Battery
A lithium battery (FIG. 12) with a life of approximately 5 years, protects stored presets if a power
loss occurs. The battery is not used when DC power is supplied to the AXB-IRS4. Write down the
replacement date on a sticker or label by adding 5 years to the date of installation, and then attach it
to the bottom of the AXB-CAM.
