Chapter 3: System Connection
Step 3. Connect the AVS-HDB-RX(s) to the HDB output port(s) of the AVS-HDB-4TX
with twisted-pair cable.
Step 4. Connect a control device (for example, a PC) to the RS-232 IN port of the
AVS-HDB-4TX or the AVS-HDB-RX (bi-directional RS232 control, either end is
available).
To cascade an RS-232 signal among several AVS-HDB-4TX transmitters through
an RS-232 LOOP, connect the RS-232 LOOP socket to one transmitter and the
RS-232 IN socket of the next transmitter until all AVS-HDB-4TX transmitters are
connected.
Step 5. Connect an IR Receiver to the IR IN port, and an IR Emitter to the IR OUT port.
The IR signal can be transmitted
bi-directionally between a AVS-HDB-4TX transmitter and the AVS-HDB-RX(s)
receiver(s).
To cascade an IR signal among several AVS-HDB-4TX, connect the IR LOOP
socket of one of them and the IR IN socket of the next until all AVS-HDB-4TX
transmitters are are connected.
Step 6. Connect the included 24-VDC power adapter to the power port of the AVS-
HDB-4TX. The AVS-HDB-RX can be powered by the AVS-HDB-4TX via PoC.
3.4 Cascade Connection
3.4.1 Cascade AV Signal
An HDMI source signal can be cascaded to several displays via HDMI OUT/ IN.
Connect the HDMI OUT socket of the first AVS-HDB-4TX transmitter to the HDMI IN
socket of the next transmitter until all AVS-HDB-4TX transmitters are connected.
HDMI signals delivered within the first AVS-HDB-4TX can be output to other connected
AVS-HDB-4TX transmitters.
3.4.2 Cascade Control Signal
AVS-HDB-4TX supports control cascading via IR LOOP/ RS-232 LOOP to enable signal
loop output. Choose one or multiple cascade methods according to your needs.
