Power Requirements
Powering the Network Repeater
For devices using hardware revision 010, COM1 is only used for supplying power to the network repeater when
connected via ethernet.
Power to the network repeater is supplied by the N+ and N- terminals on the COM1 port and is also used for the
onboard electronics and the ethernet connection.
When the network repeater is connected to the module network via ethernet, module power is supplied to the
COM1 port via a 12VDC independent battery backed power supply unit capable of supplying the required voltage.
This same power supply can be used to supply the COM1 module network spur as well, as long as the maximum
load of the power supply is not exceeded.

on Network
If the network repeater is inserted into an existing section of the module network the auxiliary outputs of a
controller can be used to supply other equipment.
Note that there is no onboard regulation or isolation for these outputs; they are a fused feed-through from the N+
N- input terminals.
When using these outputs to supply other devices, be sure not to exceed the rating of the internal fuses as
outlined in the Technical Specifications (see page 24).
