DTP HDMI 330 Tx/Rx Transmitter and Receiver • Installation and Operation 6

h 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.

Figure 4. Captive Screw Connector Wiring for Stereo Audio Output

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 Disconnecting the Ground on

page 11) because of ground potential differences, the DTP HDMI 330 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.

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 on page 9 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 (see

item e on the previous page) (see Power supply wiring on page 8 to wire the

connector).

NOTES:

• One power supply is included with the transmitter and normally can power

both units.

• If you have removed the ground jumpers (see Disconnecting the Ground

on page 11) because of ground potential differences, one DTP HDMI 330

unit cannot remotely power the other unit. Each unit requires a local power

supply.
