QUICK GUIDE TO THE TELCO/CODEC MODULE
There are three connectors on the optional Telco module: one 6-pin analog audio input connector,
one 3-pin digital audio input connector, and one 24-pin logic connector. The connectors are hidden by
the meter panel in normal operation.
AUDIO
ANALOG INPUT —
The 6-pin analog input accepts line level stereo or
mono signals. When a mono signal is connected, parallel the signal to the
left and right input pins.
D I G I TA L I N P U T —
The 3-pin digital input accepts AES-3
(AES/EBU) or S/PDIF signals (when the circuit shown on page 2-11 is used).
LOGIC
LOGIC I/O — The 24-pin logic connector allows control of the connected
device by the module, or external control of the module by the device. Logic
settings are configured by the Setup DIP switches (see Switch Definitions on
page 2-23). Additional logic information is on pages 2-24 and 2-25.
