Analog audio connectors
See figure 4 to wire a connector for the appropriate input type. Connectors are included
with the encoder, but you must supply the audio cable. Use the supplied tie-wrap to strap
the cable to the extended tail of the connector.

Captive Screw Connector Wiring for Audio Inputs
NOTES:
•
The length of exposed wires is important. 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.
A balanced stereo audio connector consists of a tip, ring, and

sleeve. An unbalanced mono audio connector consists of a tip
and sleeve. When you are making connections for the units
from existing audio cables, see the drawing at right to identify
the tip, ring, and sleeve parts of the connector. The ring, tip,
and sleeve wires are also shown on the captive screw audio
connector diagram (see figure 4).

Control Connector Wiring
NOTES:
•
The IR S and G line pair and the RS-232 Tx and Rx line pair must each cross once
between this connector and the source or destination.
•
The length and preparation of exposed wires is important (see the audio connector
above for details).
