One or more Repeater Units can be used in a CompoNet Network to use both
round cable I and round cable II, or round cable I and Flat Cable I/II under the
same Master Unit.
The I/O power supply to multi-power supply Slave Units may be a source of
noise depending on the connected devices. Even when supplying the commu-
nications power supply together to all Slave Units, use a separate I/O power
supply so that noise does not affect the network.
When supplying communications power and I/O power, the allowable currents
of cables and connections, the voltage drop, and the capacity and location of
power supplies must be considered.
Do not allow the total current consumption of all Slave Units to exceed the
allowable current of the communications cables and connectors. Exceeding
the allowable current may result in heating or burnout of the cables or connec-
tors.
