Step 5: Connect the RS-232 port of the devices to control to the receiver or the
transmitter.
Step 6: Connect the 24-VDC power adapter to either the transmitter or receiver.
NOTE: The power supply is not required on both ends. Only one of the units,
transmitter or receiver, requires power.
3.3 Application
Use the AVS-HDB-TX and AVS-HDB-RX for computer monitoring, conference rooms,
large-screen displays, television, education applications and more.
3.4 Twisted-Pair Cable Connection
The twisted pair used with the extender MUST be a straight-through cable. The connec-
tors can be T568A or T568B, but both sides must be the same.
Figure 3-2. Cable pinout diagram.
NOTE: Cable connectors must be metal, and the shielded layer must be connected to
the connector's metal shell to ground the cable.
3.5 Extending Transmission Distance
The AVS-HDB-TX, AVS-HDB-RX, and AVX-HDB-4TX extenders, and AVS800 and
AVS1600 switchers work with the Multi-Format Video Scaler with Extension - 5-Port
(AVSC-5DA1-HDB) to extend the transmission distance of an HDMI/IR/RS-232 signal.
