These two 4-pin terminal block connectors, located on the bottom side of the
QM-FTCC, are for connection to the Cresnet network. One connector is used
to connect to the Cresnet network while the second connector can be used to
connect another Cresnet device. Cresnet power to the QM-FTCC is supplied
through either of these connectors. For more information, refer to "Network
Wiring" on page 13.
