Installation
RS-232 / IR Connector
The AT-JUNO-451 provides RS-232 and IR control, using the included four-pin captive screw connector.
Electrical IR or RS-232 signals, from a control system, can be used to control the AT-JUNO-451. Atlona recommends
the AT-LC-CS-IR-2M (sold separately) for easy connection to the captive screw connector.
1. Use wire strippers to remove a portion of the cable jacket.
2.
Remove at least 3/16” (5 mm) of insulation, from the end of each wire.
3. Insert the wires into the correct terminal on the included captive screw block, as shown below.
4. Tighten the screws to secure the wires. Do not use high-torque devices as this may damage the screws and/or
connector block.
The illustration below, shows an example of how electrical IR or RS-232, from a control system, or the included IR
remote, can be used to control the AT-JUNO-451.
