2.7.8. 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.

2.7.9. 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.
