Introduction & Installation
What is the 8380 RPC?
The 8380 RPC™ Return Path Combiner is a 16 x 1 non-blocking RF matrix switch designed
for use with the VIAVI 8310 RSA™ in the return path of CATV systems. The 8380 RPC has 16
input ports that can be combined into a single output.
There are two versions of the 8380 RPC available, a master and a slave. The master 8380
RPC is used to control each slave using an RS-485 connection. The output from each slave
8380 RPC connects to a corresponding input on the master unit. Slave 8380 RPCs have the
ability to be upgraded to a master unit.
A complete 8380 RPC system consists of a master and 16 slaves allowing for 256 inputs to be
combined into a single output. The output of the master may be used for a variety of tests.
Whether you are a technician in the headend or the eld, the master 8380 RPC can be
controlled from any location with an Internet connection. The 8380 RPC includes a built-in web
based conguration that is compatible with any web browser including those on mobile devices
and the DSP family of devices.
This versatility allows the technician to connect many ports, but only sweep on the ports they
are currently testing, while the other ports remain on stand-by.

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 conguration of
Master units and to perform rmware 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 conguration 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
rst 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.

Installing the 8380 RPC
The following section explains the procedure used to physically install the 8380 RPC. In order
to properly setup the 8380 RPC the following steps must be completed in this order. Do not
skip any steps.
DO NOT plug in the power cord of the 8380 RPC until
instructed below.
1. Mount the 8380 RPC in a standard rack using four retaining screws.
2. Connect an ethernet cable to the master unit.
3. Connect the RS-485 cables and set the addresses and terminations of the master and
slave units accordingly.
4. Plug the AC to DC Power Adapter of the 8380 RPC into the Power Input and then into
an AC power source. When power is supplied to the 8380 RPC, the Power LED on the
front panel of the unit will illuminate.
If the Power LED is not illuminated upon connecting power to
the 8380 RPC, contact 1-844-GO-VIAVI for assistance.
5. When the unit is ready for operation, the Status LED on the front panel of the unit will
illuminate.
Upon reboot (regardless of source/cause), the master 8380
RPC will load the last saved device settings, system settings,
user settings, and network conguration as well as deactivate
all ports present in the 8380 RPC system.

Installing the 8380 RPC
The following section explains the procedure used to physically connect multiple 8380 RPC
units using the RS-485 Control Port. In order to properly setup the 8380 RPC the following
steps must be completed in this order. Do not skip any steps.
Unit Installation
When installing a Master unit
with several Slave units, the
Master unit should always be
placed in the middle of the
“stack”. Then, Slave units 01
through 08 should be placed
above the Master unit and
Slave Units 09 through 16
should be placed below the
Master unit.
This method of installation is
used to reduce the required
cable length between Master
and Slave units while keeping
the connections from having to
cross each other.
All units should use the same
length cable. The cable length
is determined by the longest
length needed as measured
from the COM port of the Slave
unit furthest from the Master
unit to the corresponding input
of the Master unit. Once the
cable length is determined,
ALL cables connecting the
Master unit to the Slave units
should be the same length.

RS-485 Connections
Connect the RS-485 Control Port from the Master unit to the RS-485 Control Port of the
Slave unit. Continue connecting the RS-485 Control Port of each Slave unit to the RS-
485 Control Port of the next Slave unit until all Slave units have been connected. See the
following diagram for an example of the typical RG-59 & RS-485 connections.

RS-485 Addressing
The RS-485 Address DIP Switch is used to set the RS-485 address of each 8380 RPG.
The address is determined by adding the two values shown below each switch that is set to
ON. See the following table for an example of each switch setting.
The RS-485 address of the Master is automatically set to 16, and the termination for the
last slave at each end of the RS-485 chain must be set to ON.
See next page for a Table of Dip Switch Addresses and Settings.
The device number is equal to the RS-485 address plus one.
