AT-HDVS-150-KIT
RS-232
Audio
The AT-HDVS-150-RX provides RS-232 control between an automation system and an RS-232
device. This step is optional and is used when connecting a computer that is running the control
software.
1.
Use wire strippers to remove a portion of the cable jacket.
2. Remove at least 3/16” (5 mm) from the insulation of the RX, TX, and GND wires.
3. Insert the TX, RX, and GND wires into correct terminal on the included Phoenix block. If
using non-tinned stranded wire, presss the orange tab, above the terminal, while inserting
the exposed wire. Repeat this step for the TX, RX, and GND connections.
The
AUDIO OUT
connector on the AT-HDVS-150-RX provides the connection of either balanced
or unbalanced audio outputs using XLR connectors. Use the included 5-pin captive screw
connector.
Balanced audio connections use two signal wires and a ground to minimize interference in audio
signals. Unbalanced audio connections use one signal wire and a ground and are used if system
components don’t support balanced signals.
