It is possible to use these RCU units to control Peak Communications' front panel LCD style units, e.g.
ILAH, IBUH, IBDH etc. However it should be noted that in these situations the unit being controlled will not
indicate if it is online or offline as it has no such knowledge, it will just think it is online all the time. The
actual unit that is online can be deduced from the RCU as normal.
REMOTE
If the RCU100 1:1 or an RCU200 1:2 has been purchased with Ethernet, there will be a RJ45 connector on
the rear of the unit.
POWER CONNECTIONS
The unit contains a redundant linear power supply arrangement. The voltage input can be set on the input
sockets to the voltage required (nominally 120 volts or 230 volts) by removing the voltage selector and re-
positioning. The settings on each side should be the same to avoid generating damage by feeding the wrong
voltage but it is possible to have them set differently. The unit is designed to work off one or both of 2 feeds
and whichever one is present then it is automatically selected. The phases of the supplies can be phase
unrelated but caution should be taken when both feeds are brought close together because a very high mains
voltage can be generated.
CONNECTOR DESIGNATIONS
The connectors on the rear of the RCU units are labelled such that the RCU can be used for both up and
down converter configurations. These are the Inputs/Outputs compared with the labelling for both units.
Converter units are designated Unit A and Unit B, which match the front panel legend and Unit S as the
Standby in RCU200 configurations

15 way D type RS232/485 serial interface. Configuration for baud rate and
addresses are set inside the unit as described later.
