1. Combined Output – This is the combined output of the 16 return path inputs.
2. Return Path Input (1 through 16) – These are inputs 1 through 16 of individual
return path ports that the 8380 RPC combines into a single output.
3. USB Port – This is a USB Type B connector that is used for initial configuration of
Master units and to perform firmware upgrades. Upon removing the USB cable from
the 8380 RPC, the power to the device should be cycled.
4. RS-485 Control Ports – These are RJ-11 Master/Slave control ports for use when
connecting master units to slave units.
5. Ethernet Port – This port is only available on Master units and is used to directly
control the 8380 RPC system via a network connection. Initial configuration using the
RPC Setup Software must be completed prior to connecting to the Master unit via
a network connection. The ethernet connection to the Master unit should be made
prior to powering the unit.
6. RS-485 Address DIP Switch
– This DIP switch is used to set the RS-485 control
address of the 8380 RPC. This is also used to enable the RS-485 termination on the
first and last 8380 RPC in the RS-485 communications chain. It is recommended
that all RS-485 connections be made prior to powering the corresponding units.
7. Power Input – Connect the included AC to DC Power Adapter to this port.
