Advanced Operation
IR can be used to control either source devices at the headend or devices connected to the receiver endpoint, such
as a display. Note that the
MASTER RS-232 / IR
port does
not
support IR control. Note that each
RS-232 / IR
port is assigned to an
HDBaseT OUT
port. This assignment is fixed and cannot be changed, as shown in the table
below. IR is compatible with frequencies from 30 kHz to 60 kHz.
1.
Remove at least 3/16” (5 mm) of insulation from the TX and GND wires.
2.
Locate the included 5-pin captive screw block and open each of the terminals by turning the screws counter-
clockwise, using a small regular screwdriver.
3. Insert the TX and GND wires into correct terminal, as shown, and tighten the screws to secure each wire. Do not
overtighten.
4. Connect the captive screw connector to the
RS-232 / IR IN
port of the zone to be controlled.
5. Connect the TX and GND wires to the control system.
