Getting Started
Thank you for purchasing a Videosys IDU, we hope that you will find the necessary
information within this manual and our specific quick setup guides, if however, you
require additional support please don’t hesitate to contact your local distributor.
Introduction
The Videosys camera control system allows you to replace the cables between your
Remote Control Panels, Camera Control Units and Cameras, the Videosys IDU connects
directly to existing control panels and in combination with other components from the
Videosys camera control range will provide a robust broadcast quality solution.
The Videosys camera control solution consists of three distinct components; an ‘IDU’(In
Door Unit), ‘ODU’(Out Door Unit) and an ‘RX’(Receiver). Multiples of these components
can be used to best fit the operators’ requirements, for example multiple IDU’s can be
connected to allow for many camera control paths over one ODU. Multiple ODU’s can be
used to increase RF coverage, and each camera to be controlled requires an RX.
From this point on to avoid ambiguity and keep things concise, the terms IDU, ODU, RCP
and RX will be used.
Principal of Operation
Our camera control system can be configured to operate using one of two fundamentally
different architectures, descriptions of the architectures and their relative advantages
and drawbacks are as follows:
Uni-directional
In this mode the IDU acts as a ‘Virtual Camera’ and talks to the RCP via its native
protocol. Changes to this Virtual Camera are then encoded into our low latency protocol.
Encoded data is routed from the IDU to the ODU where it is transmitted. Data is then
received via the RX, within the RX a ‘Virtual Panel’ is updated with the received
information, the ‘Virtual Panel’ then communicates with the camera using its native
protocol.
•This approach allows high performance even within an extremely poor RF
environment; as data loss will not cause link failure.
•Uni-directional operation boasts simple setup, as only one data path needs to be
configured.
•Due to the use of an intermediate protocol, Uni-directional operation allows
operators to mix and match different manufacturers cameras and control panels.
•As each command has to be specifically implemented and handled, not all of the
features available on manufacturers cameras and control panels will be available
when used with a Uni-directional control link.

WWW.VIDEOSYS.TV 5
Bi-directional
In this mode an RCP natively communicates to the IDU, data is then conditioned and
forwarded on to the ODU, where it is then transmitted. An RX then receives transmitted
data and communicates with the manufacturers camera. Return data is fed from the RX
via a return path, back to the IDU. Typically, this return path would be via the data path
provided on many COFDM video transmitters.
•All of the features that would be available via a cabled setup are available via our
Bi-directional setup.
•Due to the bandwidth restrictions of the RF path, RCP wakeup times might be
slightly longer than in a wired or Uni-directional set up.
•Because of the reliance on two communication paths, wireless control is not as
robust as with Uni-directional operation.
Depending on the specific requirements of your application, Bi-directional or Uni-
directional should be selected.

Connecting Components
The first step is to connect the components of your camera control system.
RCP
This can be connected via an Ethernet network using the RJ45 connector, or via the
appropriate cable to the numbered legacy connectors on the back of the unit. A range of
pre-made cables and cable wiring diagrams are available on our website or via
contacting your local sales representative.
ODU
There are two options for connecting to an ODU, either via the Data Out Connector or
using the RJ45 and via an Ethernet Network.
Tally
The IDU can be connected into an existing tally system via the Tally Input Connector,
this will respond to contact closure, open collector input and TTL logic levels (inverted).
Power
Connect 12V DC to the Power input XLR connector. When powered the unit will display a
boot screen and then present the user with a status screen.

WWW.VIDEOSYS.TV 7
Navigating Menus
The Up, Down, Left, Right, Enter and Cancel buttons can be used to navigate through
the menus. Menus are organised into lists, these can be scrolled through with the Up and
Down buttons. To enter the selected submenu or option, press the Enter button. Cancel
will return you to previous menu, potentially discarding any unsaved changes made
within the current menu. The Left and Right buttons are predominantly used to select
which character is being edited in settings such as IP address or Frequency.
Status Screens
The first screen that will be displayed to the user is the status screen, depending on the
mode that the unit is set to this will either be the Uni-directional control status screen
(fig 1) or the Bi-directional control status screen (fig 2)
Fig 1. Uni-directional operation mode status screen
Fig 2. Bi-directional operation mode status screen
Uni-directional Status Screen
The Uni-directional control status screen has numbered rows that represent the RCPs
that the IDU can connect to. There can be a maximum of four RCPs per IDU, although
your unit may display less depending on licencing. Each RCP can have two states;
Connected or Disconnected. When an IDU and panel are successfully communicating
‘Connected’ is displayed.
In Uni-directional mode the IDU does not know, and therefore cannot tell the user
anything about the transmit, receive or RX to Camera connection status.
Bi-directional Status Screen
The Bi-directional status screen has numbered rows, each representing connection to a
camera, these connections can have the following status:
‘Not ready’ –This states that a full bi-directional loop cannot be made, this could mean
that a link to the camera or panel has not yet been established, or that there is a fault
with either the forward or return path. You can use the up and down controls to scroll
through the individual status pages for each of these connections.
‘Sync…’ – this states that all of the required links are up, and connections made, but that
devices are ‘waking up’ and synchronisation data is being transferred, and it is therefore
not usable for camera control. This process happens as soon as the required connections
are made and typically takes a few seconds, depending on the camera manufacturer,
manufacturer’s hardware, software and feature count.
‘Active’ – All connections are good, camera parameters and values have been
synchronised and the systems is ready to use.

Menu Structure
Fig 3. IDU menu structure diagram
Pressing enter will move the user from the status screen to the Main menu, this main
menu allows the user to navigate to a category, these are as follows;
‘CameraMfg’ –Allows the user to select a camera manufacturer, depending on the
camera it might also guide the user through menus asking which camera models are
being used. There are then options for Serial, Ethernet, Bi-directional or Uni-directional.
‘CameraNumbers’ –Sets which camera numbers are matched to which channels, these
camera numbers are used to specify which receiver is listening for that data.
‘Network’ –Contains submenus for the IDUs IP settings, Channel IP settings and
Camera Network settings. Channel settings are the IP addresses for panels to connect to
via IP. Camera Network settings has manufacturer specific settings such as specific ports
to use for connection.
‘Radio’ –Communicates with an ODU that is connected via the data connector,
displaying and allowing the user to modify the radio frequency and transmit power.
‘System’ –Contains a range of settings relating to the IDU itself, Serial numbers,
Licence options, Data output, Paint settings reset and version information.

Web Interface
The IDU has a built-in webserver and serves a range of useful control pages, if you have
a device with a web browser on the same network, you can use this interface to quickly
change settings, perform updates and utilise the virtual RCP feature.
Accessing the Web Interface
To Access the Web interface, firstly power up your IDU and connect a PC or laptop up to
the same IP network as your IDU. Find the IP address of your IDU (this can be found via
Network -> IDU settings -> IDU IP Address) and enter this into your browser, this will
take you to the IDUs configuration web page.

Navigating the Web Interface
Once you have loaded the webpage (see ‘Accessing the Web Interface’), you should see
the ‘Network’ Page (fig 4), from this page you can easily and quickly configure the unit
as part of an IP network. There is also a ‘Maintenance’page (fig 5), giving device
information and allowing for updates (these can be found on our website). The ‘Front
Panel’page (fig 6) literally mirrors the information presented on the IDUs front panel
and allows for all of the same functionality as the units’ physical front panel. There is
also a ‘Remote Panel’ page (fig 7); this is a ‘Virtual RCP’and allows for all of the settings
that we support in Uni-Directional mode to be controlled directly from the browser.

Unit Updates
To update your IDU, firstly you will need to obtain a new firmware image, these are
available on our website. Please check the release notes bundled with the firmware
images carefully, they will explain precisely what changes have been made. The next
step is to access the webpage (see ‘Accessing the Web Interface’). On the ‘Maintenance’
page fig 5. you will find a software update section, use this to select and upload the file.
During the update you will notice that the IDU will inform you that it is restarting and
then that it is updating. If you have any questions about which firmware image you
should be using or require any additional support please your local distributer.
