Crestron ST-IO Input/Output Module
NET
These two 6-pin, RJ-12 modular jacks are used to connect the ST-IO module to a
Cresnet control system. When the module is part of the Cresnet system, power may
be supplied via NET if within system power and cable length limits; the supplied
power pack is optional and need not be attached. Two NET ports are available so
that network units can be daisy-chained together. Review the latest revision of the
Network Modular Cable Requirements (Doc. 5682).

NOTE: Most 4-conductor phone cables are wired in a crisscross fashion and are not
compatible with Crestron equipment.
If the power pack is attached when the module is part of a Cresnet system, power is
drawn from the power pack. The module does not draw from the network power, but
the network power remains chained.
DIGITAL IN (1, 2, 3, 4, & G)
This 5-pin connector (four inputs and one common) is used to detect digital input
levels in either closure or voltage mode.
RELAY OUTPUT (1 through 8)
This 16-pin connector provides eight isolated, normally open, relay contact pairs.
Indicators
There are 14 LED indicators located on the front panel of the ST-IO. Refer to
