CAUTION: For unbalanced audio, connect the sleeves to the ground contact.

DO NOT connect the sleeves to the negative (-) contacts.

NOTE: The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).

• If the stripped section of wire is longer than 3/16 inch, the exposed

wires may touch, causing a short circuit.

• If the stripped section of wire is shorter than 3/16 inch, wires can be

easily pulled out even if tightly fastened by the captive screws.

i RS-232 and IR connector — Connect a serial RS-232 signal, a modulated IR signal,

or both to this 3.5 mm, 5-pole captive screw connector for bidirectional RS-232 and IR

communication. See “RS-232 and IR connector wiring“ to wire the connector.

j Power input connector — Plug the included external 12 VDC power supply into

either this 2-pole connector or the power input connector on the transmitter (item

See “Power supply wiring“ to wire the connector.
