AT-UHD-CAT-8
The AT-UHD-CAT-8 provides five
RS-232
ports. The
RS-232/IR MASTER
port is used to control
the AT-UHD-CAT-8 using a control system or other DTE equipment.
RS-232/IR 1
through
RS-
232/IR 8
ports are used in conjunction with the
HDBaseT OUT 1
through
HDBaseT OUT 8
p
orts. RS-232 data is passed through over the respective
HDBaseT OUT
port (zone) to a sink
device connected to a PoE-compatible the receiver. This step is optional.
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 using one of the included 5-pin
captive screw connectors.
4. Tighten the captive screws to secure the wires in place. Do not over-tighten or use high-
torque devices to prevent damage to the connector block.
NOTE:
Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for
ground. On some devices functions of pins 2 and 3 are reversed.
