SilverBack V Camera-Mounted Tx Unit
The SilverBack-III family’s Camera side unit, also known as a “TX unit”, connects to a
camera’s rear battery plate (or it can be located separately, if required) and all the
signals from the camera are fed into this unit via a SMPTE hybrid cable (which includes
power) and communicates to a connector on the base station. This signal transport is
bi-directional, coming from the camera to the base station and vice versa.
Once mounted on the camera (via an Anton Bauer or “V”-mount battery bracket) the
SilverBack unit can have include an additional battery mounted on the outside of the
Camera I/O unit for extra protection against power failure or for working where readily
available AC power is not present.
The TX control panel’s simple interface lets the camera operator easily monitor system
link and signal status via an OLED display. Pushbuttons permit easy adjustment of
intercom levels and a menu system allows more detailed configuration of system
parameters.

Camera Video Connections:
Connect the camera’s primary SDI outputs to the 4K CAM inputs on the SBV Camera
Unit. Depending on the type of camera and video resolution being used, up to 4 BNC to
HDBNC cables may be needed. The 4K CAM inputs on the SBV Camera Unit are
highlighted in Blue.
The SBV Camera Unit’s 4K CAM inputs are capable of accepting Single Link, Dual Link,
and Quad Link video signals, supporting HD, 3G, and 4K resolutions up to 4Kp60.
Once the camera’s video resolution is known, and whether it is Single Link, Dual Link,
or Quad Link, the Gear-boxing Mode in the SBV Camera Unit’s Video Settings Menu
must be set accordingly.
Menu->Video Settings->Gearbox->Mode: Single, Dual 6G, Quad 3G
If your SBV Camera Unit is not 4K capable or does not contain a Gearbox, no menu
setting is necessary for the camera video. Connect the camera’s SDI output to the
CAM input on the SBV Camera Unit.
Reference Sync Connections:
Connect the SBV Camera Unit’s REF output to the camera’s Ref/Sync input using a
BNC to HDBNC cable. This REF output from the SBV Camera Unit is either analog
NTSC, PAL, or an HD Tri-Level signal that has been supplied to the Base Unit.
If the camera requires SDI Reference, connect one of the 3G SDI outputs of the SBV
Camera Unit to the Ref/Sync input on the camera using a BNC to HDBNC cable. This
output will be the same signal that is connected to the corresponding SDI Input on the
Base Unit.
Timecode Connections and Operation:
Connect the SBV Camera Unit’s TC connector to the camera’s TC connector using a
BNC to HDBNC cable. This TC connector on the SBV Camera Unit can either be an
output or an input, supplying Timecode to the camera from the Base Unit or sending
Timecode to the Base Unit from the camera.
The direction of this Timecode connector on the SBV Camera Unit is set in the SBV
Camera Unit Menus.
Menu->System Settings->Timecode->Direction

Page 5
Secondary SDI Connections
The SBV Camera Unit may be equipped with 1 or more secondary SDI paths,
depending on the model number ordered. These may be all camera returns, all sends,
or a combination of both. The secondary SDI paths are 3G capable, they do not
support 6G or 12G SDI.
The secondary SDI connectors on the SBV Camera Unit are highlighted in Green and
the label indicates their direction. Connect your secondary SDI signals using BNC to
HDBNC cables.
Built-in Viewfinder Switch
On SBV Camera Units configured with either Dual SDI returns or a single SDI send and
single SDI return, a built-in Viewfinder Switch feature is available to switch an externally
connected Viewfinder between the camera’s monitor output and a return video feed.
This feature may be disabled in the SBV Camera Unit Menus if this functionality is not
needed.
Menu->Video Settings->Viewfinder->Enable: On. Off
Menu->Video Settings->Viewfinder->Slot Num: 1-4 (depends on the number and type of SDI cards
installed)
Connect the camera’s Monitor output or secondary SDI output to the viewfinder CAM
connector on the SBV Camera Unit using a BNC to HDBNC cable. Connect the
viewfinder OUT connector on the SBV Camera Unit to the SDI input of the external
Viewfinder monitor using a BNC to HDBNC cable.
Note that the directions of the Secondary SDI BNC connectors on the SBV Camera Unit
will be different when the Viewfinder Switch is enabled versus when it is disabled.
When the Viewfinder switch is enabled, the Viewfinder button on the SBV Camera
Unit’s control panel is used to select the video source that is output from the Viewfinder
HDBNC Connector. Pressing this button will change between the video signal
connected to the VF input (typically the Camera’s video output) and the Return 1 video
being sent by the base station. LED’s on the control panel indicate which source is
currently switched to the Viewfinder output.
An external switch connected to the DB-15 GPIO connector on the SBV Camera Unit
may also be used to control the Viewfinder output, please refer to the pinout guide for
pinout information. The Viewfinder select pin on the GPIO connector is typically used
with a momentary type pushbutton switch. When this pin is connected to Ground, the
Viewfinder Output HDBNC will output Return 1 video. When this pin is left open or
unconnected, the Viewfinder Output HDBNC will output the video signal connected to
the VF input (typically the Camera’s video output).

SilverBack V Base Rx Unit
The SilverBack V family’s Base side unit, also known as a “RX unit”, connects to up to 2
camera units and all the signals from each camera chain are fed into this unit via
SMPTE hybrid cables (which can include power). This signal transport is bi-directional,
coming from the camera to the base station and vice versa.
Internally, the Base Station contains redundant 12V power supplies for powering the
Base Unit electronics as well as separate individual power supplies for powering each
camera chain.
The Base Station front panel’s simple interface lets the operator easily monitor system
link and signal status via a TFT display. Dedicated status LED’s permit easy monitoring
of key signals levels and a menu system on the TFT display allows more detailed status
and configuration of system parameters.
Connecting the Base Unit
The SBV Base Unit is to be mounted in a standard 19” equipment rack. AC connector 1
is used to power the Base Unit and Camera Chain 1. AC connector 2 is used to power
Camera Chain 2 and provide redundant power to the Base Unit.

be set accordingly.
Base Menu->Settings->Video->Cam1 Output: Single Link, Dual Link, Quad Link
Base Menu->Settings->Video->Cam2 Output: Single Link, Dual Link, Quad Link
If your SBV system is not 4K capable or does not contain a Gearbox, no menu setting is
necessary for the camera video. Connect the camera SDI output on the SBV Base Unit
to the desired facility destination.
Reference Sync Connections:
Each camera chain in the SBV Base unit has a dedicated Reference Sync Input.
Connect the desired sync reference to these ports. This REF input can accept either
analog NTSC, PAL, or an HD Tri-Level signal. The 2 HDBNC connectors for each
camera chain’s reference are internally connected together as a loop-thru. It is
recommended to put a 75 ohm termination on the loop-thru connector.
The SBV Base unit also has the ability to route either of the Reference Sync inputs to
either or both camera units. This way, only a single reference signal is needed per
frame. The Reference Sync routing is configured in the SBV Base Menus.
Base Menu->Settings->Reference>Cam1 Ref: In1, In2

Base Menu->Settings->Data->Cam2 Data 2: RS232/422, LANC
Frame Controller
You can monitor the status and control settings in your SilverBack V Base frame via a
Web page dashboard that is embedded within the frame. The steps for connecting to
your facility’s Ethernet network will depend on the network requirements of your facility.
Contact your IT Department before connecting to your facility network to ensure that
there will not be any conflicts.
Network Settings:
The method for setting the IP address of the SilverBack V Base Unit is determined
using the 4-position DIP switch on the rear of the chassis. The four possible settings for
IP address configuration are outlined below:
• Preset IP address configuration — the network controller card in the frame can be forced to use
one of two specific predefined IP address settings. This can be used to establish initial
communications, configure the frame for future deployment on another network, or to override a
custom user configuration.
• User-defined IP address configuration — the network controller card in the frame can be
configured to use a user-defined static IP address from the device’s embedded Web page. Re-
configuration can only be done once network communications have been established.
• Automatic configuration using DHCP — the network controller card in the frame is configured to
automatically obtain network settings from a Dynamic Host Configuration Protocol (DHCP)
server. This method would be recommended for advanced users only as there is no way to
display the DHCP assigned address on the frame itself.
The physical DIP switching settings are shown below. Only one switch is allowed to be
in the ON position.

Factory default is 192.168.1.249
3
Fixed IP Address #1. 192.168.2.2
4
Fixed IP Address #2. 10.1.1.2
Note — The IP Addresses of the SilverBack V Base Unit and your computer must be on
the same Subnet. For example, if the SilverBack V Base Unit has an IP Address of
192.168.2.2, then your computer should be configured for an IP address of 192.168.2.X
where X is a number other than 2.
To use one of the fixed preset IP addresses:
1. Set the DIP Switch to specify the desired preset IP address as outlined in the IP address DIP
switch table.
2. Ensure the network settings of your computer are compatible with those chosen for the
SilverBack V Base Unit frame. Both your computer and the SilverBack V Base Unit must be on
the same subnet. Contact your IT Department if you need help determining or configuring the
network settings of your computer.
3. To prevent any possible IP address conflicts, initially isolate the SilverBack V Base Unit frame
and your computer from the rest of your network.
• If you are using a hub or switch, unplug all devices except the SilverBack V Base Unit
frame and your computer
or
• Connect the SilverBack V Base Unit frame directly to your computer with an Ethernet
cable.
4. Launch a web browser on your computer.
5. Power up the SilverBack V Base Unit frame.
6. In the address bar of the web browser, enter the preset IP address selected on the DIP switch.
7. Wait approximately 30 seconds while the frame establishes network communications.
8. Verify that the SilverBack V Base Unit Dashboard webpage displays in the web browser.
9. Should the webpage fail to display after a minute or two:
• Click the refresh/reload button in your browser.
• Verify the Ethernet cables are properly connected.
• Check the link/activity LEDs found on the Ethernet RJ-45 connectors.
• Verify that you have properly performed each step of this procedure.
• Contact MultiDyne Technical Support if you cannot establish a connection

Page 15
To use a Custom User IP Address via webpage Dashboard
Once network communications have been established with a SilverBack V Base Unit, a
custom static IP address can be configured through the Frame Ethernet Settings box in
the webpage Dashboard.
To configure the User IP address using the webpage Dashboard:
1. Establish Ethernet communications with the SilverBack V Base Unit using one of the preset
IP addresses, DHCP, or previously configured User IP address and load the device's
Dashboard webpage in a web browser by entering the IP address in the browser's address
bar.
2. In the Frame Ethernet Settings Box, enter the desired User IP address in the User IP boxes.
3. Ensure the new network settings chosen for the SilverBack V Base Unit are compatible with
the network the SilverBack V Base Unit is to be employed in. The computer used for
monitoring the SilverBack V Base Unit must be on the same subnet. Contact your IT
Department if necessary.
4. Verify the IP address entered is correct and then click the "Save IP" Button. This IP address
will be stored in non-volatile memory on the frame controller card.
5. The new IP address will not take effect until the IP Address DIP switch is changed to the User
IP address position. If the DIP switch is already in the User IP position, a toggle of the User
IP position switch from off to back on again may be required for the new address to take
effect.
6. Enter the new IP address in the address bar of a web browser and hit enter to verify the new
IP address.

Page 16
To use DHCP to automatically assign network settings
Network settings for the SilverBack V Base Unit may be automatically configured via a
DHCP server on the facility network. This method would be recommended for
advanced users only as there is no way to display the DHCP assigned address on the
frame itself.
To configure the network settings via DHCP:
1. Connect the SilverBack V Base Unit to your network using an Ethernet cable.
2. Power up the SilverBack V Base Unit.
3. Set the DIP Switch position 1 to ON to specify DHCP configured settings.
Physically Identifying a SilverBack V Base Unit in a facility
On the rear of the chassis, there is an ID LED which can be used to help identify the
location of a particular SilverBack V Base Unit. The Frame ID LED button in the
Ethernet Settings Box of the webpage allows you to turn this LED ON or OFF. When
turned ON, the LED on the chassis will blink.
