2.6.5. S/PDIF digital audio input and output

Some interface modules have standard RCA receptacles for digital coaxial audio inputs
and outputs.
Info: Plugs and sockets on consumer equipment are conventionally color-coded by CEA/CEDIA-
863-B (ANSI) to aid correct connections. According to the standard Lightware devices are
supplied with orange colored RCA connectors for S/PDIF signals.

2.6.6. Symmetrical analog stereo audio

5-pole Phoenix connector is used for symmetrical analog audio. The connector is used on
certain interface modules as a configurable input or output. Always check if this connector
is configured as an output or input to prevent connecting two outputs together.
Asymmetrical audio signals can be connected as well. For asymmetrical output, connect
only + and ground. For asymmetrical input connect + and ground to the source and connect
– to the ground.
Compatible plug type:
Phoenix® Combicon series (3.5mm pitch), type: MC 1.5/5-ST-3.5, order nr. 1840395.

2.6.7. IR connectors

IR Receiver and Transmitter are connected with TRS (Tip, Ring, and Sleeve) connectors.
They are also known as (3,5 mm or approx. 1/8") audio jack, phone jack, phone plug or
mini-jack plug.
