Audio output connector — This 5-pole, 3.5 mm captive screw connector outputs
the transmitted, unamplified, line level analog audio. Connect an audio device, such as
an audio amplifier or powered speakers.
See figure 4 to properly wire a captive screw output connector. Use the supplied
tie-wrap to strap the audio cable to the extended tail of the connector.
Do not tin the wires!

ATTENTION: For unbalanced audio, connect the sleeves to the ground contact.
DO NOT connect the sleeves to the negative (-) contacts.
NOTES:
• If you have removed the ground jumpers (see
page 12) because of ground potential differences, the DTP HDMI 230 cannot
extend analog audio. No analog audio is output.
• 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.
• Do not tin the power supply leads before installing them in the connector.
Tinned wires are not as secure in the connector and could be pulled out.

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

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 (see
e
item on page 5). See
NOTES:
• One power supply is included with the transmitter and normally can power
both units.
• If you have removed the ground jumpers (see
on page 12) because of ground potential differences, one DTP HDMI 230
unit cannot remotely power the other unit. Each unit requires a local power
supply.
