These two 6-pin, 6-position RJ11 modular jacks are used to connect the ST-COM
module to either the SmarTouch STS or Cresnet remote control system. When the
module is part of the Cresnet system, power is provided via the NET connection; the
power pack 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).
