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.

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.

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.

For security purposes when entering the password, the eld only displays an asterisk (*)
instead of the typed characters.
Passwords support up to 12 characters and must be at least one character to be
considered valid. Note that certain characters ( ‘, “, and \) cannot be used. If a password
containing errors is submitted, the 8380 RPC will reject the changes and an error
message will be displayed.
Privilege
The user’s privilege can be set to Administrator or Field User by selecting the
corresponding setting from the dropdown list. Selecting Remove will remove the user
from the active users for the 8380 RPC System.
Note that User Number 1 (Default User) must always have its privilege set to
Administrator. This ensures that there is always at least one administrator for the 8380
RPC system.
There is no upper limit to the number of administrators and/or eld users that can
be present simultaneously. For example, there is no reason why all users could not
have administrative privilege. The maximum number of users is 24 regardless of their
privilege.

Device Settings
The Device Settings page allows
users with Administrator privileges to
set the name of all devices and ports,
the presence of each device (with the
exception of the master, which is always
present), and the presence of each
individual port for each device on the
8380 RPC system. Device/port presence
(see Display column) indicates that the
device/port should be displayed on the
Select Ports page. This feature is used
to control which devices/ports users have
access to on the Select Ports page.
The Device Settings page displays a
dynamically built table that populates
its cells based on the device name and
number selected.
See the following sections for more
information on how to adjust the device
settings.
To save changes to your device settings,
select Submit. To refresh the form without
saving, select Reset.
Note that changes can only be submitted
for one device at a time.

Device and Port Names
Device names support up to 20 characters and must be at least one character to be
considered valid. Note that certain characters ( ‘, “, and \) cannot be used. If a device
name containing errors is submitted, the 8380 RPC will reject the changes and display a
message indicating the error.
Port names follow the same rules as device names with the exception that the port
names only support up to 12 characters.
Adding and Removing Devices
Addition
Each slave device may be added to the 8380 RPC system by selecting the checkbox
next to the device name eld.
Once the slave device has been added, the master routinely polls it for its current
switch states. This allows the master to verify the slave is functioning properly and
responding to RS-485 commands.
If RS-485 communications between the master and slave are interrupted for any
reason, the master will automatically ag the error (slave device name will be grayed
out on the Select Ports page, and the user will not have access to the slave ports)
and will deactivate all ports associated with the device in error. Note that the ports
that were previously activated do not reactivate when the connection is restored.
In the case of an RS-485 communications error, the Status LED lights on the Slave
will blink to indicate the error.
Removal
Each slave device may be removed from the 8380 RPC system by deselecting the
checkbox next to the device name eld.
Once the slave device has been removed, the master will automatically deactivate
all ports associated with the device removed. The device will also be removed from
the Select Ports page.
When upgrading the rmware of the Master 8380 RPC, it is
best to rst remove all slave devices from the system using
the Device Settings web page. This will prevent the Master
8380 RPC from attempting to communicate with the Slave
units during the upgrade process, which is desired.

Adding and Removing Ports
Addition
Each individual port of each device on the 8380 RPC system can be added by
selecting the checkbox next to the port name eld under the Display column.
Note that adding a port to the 8380 RPC system does not mean that the port is
active. Before the new port can be accessed, the corresponding device must be
added to the 8380 RPC system.
Removal
Each individual port of each device may be removed from the 8380 RPC system by
deselecting the checkbox next to the port name eld.
Once the port has been removed, the master will automatically deactivate the port if
necessary.
Removing a master port prevents the corresponding slave device from being
accessed from the Select Ports page, and it automatically removes the slave
device from the 8380 RPC system. Also, all active slave ports for the device will
automatically deactivate upon removal of the master port.

System Date/Time
If the Update System Date/Time checkbox is selected, the date/time of the system
will be updated upon submission to the master device. There are two distinct ways of
controlling the date/time settings of the 8380 RPC system as follows:
PC (Auto) – This method retrieves the current date/time from the user’s PC or
mobile device.
User (Manual) – This method allows the user to specify each individual parameter of
the date/time settings. The user may set the day of the week, day of month, month,
year, hours, minutes, and seconds.
Port Timeout (Hours)
If the Update Port Timeout (Hours) checkbox is selected, the port timeout of the
system will be updated upon submission to the master device.
The port timeout setting is used to control the automatic deactivation of all active ports.
The port timeout is adjusted by selecting the number of hours (0 for no timeout, 1 to 72,
default of 24) from the dropdown list.
This parameter does not imply that all active ports deactivate at the same time, but they
will remain active for the same amount of time before automatically deactivating.

Adding a New User
When adding a new user to the 8380 RPC system, all user parameters (user name,
password, and privilege) must be added. The maximum number of users is 24.
Removing a User
To remove a user from the 8380 RPC system, with the user number selected,
select Remove from the Privilege dropdown box. Note that removing a user clears
their information from the master device and will result in the master automatically
deactivating all ports associated with the user.
User Name
User names support up to 12 characters and must be at least one character to be
considered valid. Note that certain characters ( ‘, “, and \) cannot be used. If a user
name containing errors is submitted, the 8380 RPC will reject the changes and display a
message indicating the error.
Password
For security purposes when entering the password, the eld only displays an asterisk (*)
instead of the typed characters.
Passwords support up to 12 characters and must be at least one character to be
considered valid. Note that certain characters ( ‘, “, and \) cannot be used. If a password
containing errors is submitted, the 8380 RPC will reject the changes and display a
message indicating the error.
Privilege
The user’s Privilege can be set to Administrator or Field User by selecting the
corresponding setting from the dropdown list. Selecting Remove will remove the user
from the active users for the 8380 RPC system.
Note that the current user cannot modify their own privileges and User Number 1
(Default User) must always have its privilege set to Administrator. This ensures that
there is always at least one administrator for the 8380 RPC system.
There is no upper limit to the number of administrators and/or eld users that can
be present simultaneously. For example, there is no reason why all users could not
have administrative privilege. The maximum number of users is 24 regardless of their
privilege.

Active Port Count
Upon loading, the page displays the number of currently active ports. As the user selects/
deselects ports, the count will automatically update to reect the number of active ports that
would be present if the user was to submit the current form data. This allows the user to
preview the total number of active ports and keep track of how many additional ports they
can activate. The maximum number of active ports is 16.
Devices & Ports Table
This table is structured to allow the user to not only view the system layout, but to verify the
current status of all devices and ports in the 8380 RPC system.
Master Ports
Each master port that is selected to be displayed from the Device Settings page is
listed in the Master Ports column.
If the master port is not connected to a slave, a checkbox representing the current port
state will be displayed. Note that as slave ports are activated, the corresponding master
port is automatically activated. If all ports of a slave are inactive, the corresponding
master port automatically deactivates.
A master port may be active without affecting the active port count when connected to a
slave with active ports. Instead, the slave ports contribute to the port count. In addition,
if communications with the slave device are lost, the corresponding master port will
automatically deactivate.
Note that administrators may select/deselect any master port provided the maximum
port count is not exceeded. Field users may only select an inactive port if the maximum
port count is not exceeded, and they can only deselect ports that they originally
activated.
Slave Devices
Each slave device that is selected to be displayed from the Device Settings page is
listed in the Slave Device column.
If the slave device is present and communicating, its name will appear in black and a
radio button will be provided to access its ports. Slave devices that are specied as
present but not responding to RS-485 commands will be grayed out, and it will not be
possible to access their ports. Note that the corresponding master port must be present
for the slave device to appear.

Slave Ports
When the Select Ports page loads, the slave ports column will be empty. To view the
slave ports for a single device, select the radio button next to the desired device.
Each slave port selected to be displayed from the Device Settings page is listed in
the Slave Ports column. The column displays all present slave ports and checkboxes
indicating their current switch states for the selected slave device.
Note that administrators may select/deselect any slave port provided the maximum port
count is not exceeded. Field users may only select an inactive port if the maximum port
count is not exceeded, and they can only deselect ports that they originally activated.
