Connecting the Communications and I/O Power Supplies
Round Cable I
When round cable I is used, the communications power cannot be supplied
through the communications cable. The communications power must be sup-
plied to each Slave Unit and Repeater Unit through separate lines. For Slave
Units that require power for I/O (i.e., multi-power supply Slave Units), the I/O
power must also be supplied separately.
There is no need to provide an external communications power supply for the
Master Unit.
