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.
j 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.
k 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
f
).
See “Power supply wiring“ to wire the connector.
NOTE: One power supply can power both units. A power supply is included with
the transmitter.
