Vicon Lock Lab rear panel

The following illustration shows the Lock Lab rear panel connectors.

In this documentation, the terms socket and plug are used for female and male connectors respectively.

For additional details of the connectors, see the Lock Lab Quick Start Guide that is supplied with Lock Lab and is available for download.

Analog input connectors

Vicon Lock Lab provides 64 channels of analog signal capture , made up from eight separate connectors, each carrying eight signals. Each connector can be portioned to connect to individual force plates. Each connector contains 16 individual connections, eight signal and their eight respective grounds.

Data from third-party devices such as force plates, electromyography (EMG) equipment, potentiometers, and accelerometers can be captured and synchronized to the video capture data. The connectors supplied are used to interface to these third-party devices. Pre-configured cables can also be supplied separately for the more common force plate interfaces. For more information on suitable cables, see the documentation for your Vicon cameras.

For more information on including analog capture devices in your Vicon system, see Add analog capture devices to a Vicon system. For information on configuring your system for analog data capture, see the documentation for your Vicon software.

Link Input/Output (IO) connectors

Vicon System Connector - Link The Link socket can be made to be an input under software control. Configured this way, it enables up to three Lock units to be synchronized with each other. When you expand a Lock system with additional Lock units, the Lock with a reference video signal or VESA input signal is made the sync source by the appropriate Vicon software. In this case the software controls which unit is primary and which unit(s) are secondary. The secondary unit(s) do not transmit the Vicon Ethernet sync and timestamp packet when acting in this mode.

PoE Gigabit connector

The Gigabit Ethernet Port 8-pin RJ45 socket connects to an appropriate Vicon-supplied Ethernet switch that is also connected to Vicon cameras and the Vicon host PC directly, or through further switches. For examples of different topologies, see Vicon system configuration and connection examples.

As well as carrying all the communications to the appropriate Vicon software, the Lock Lab also receives its power over the same connections. Additionally, this port also transmits synchronization and time-stamping through special Ethernet packets to all other connected Vicon peripherals.

Earthing point

Dedicated earthing point . Ensure this is used to ground the Lock Lab.

VESA connector

• VESA Stereo In The 3-way, mini-DIN socket provides the input to the VESA Stereo In signal. When selected as the genlock source by the appropriate Vicon software, the Lock unit locks to this signal.

For details of using external VESA Stereo signal to synchronize your Vicon system to an external video system, see Add VESA stereo to a Vicon system.

Remote start/stop connectors

To trigger capture by the Vicon system from a remote control device, you must configure your Vicon application software to use the device connected to the Remote Start and Stop sockets; for details on doing this, see the documentation for your Vicon software. For details on enabling third-party remote devices to trigger your Vicon system, see Add remote triggering devices to a Vicon system.

• Remote start This RCA socket provides the external input for the start of capture, which can be activated by momentarily connecting this input to ground through either a mechanical or electronic switch. Capture is started on the first frame boundary after this event is detected.

• Remote stop This RCA socket provides the external input for stopping capture, which can be activated by momentarily connecting this input to ground through either a mechanical or electronic switch. Capture is stopped on the first frame boundary after this event is detected.

Sync output connectors

Eight RCA sockets provide sync outputs to external third-party devices for synchronizing to the Vicon system.

Each sync output consists of a configurable TTL-type drive signal which is set up through the appropriate Vicon application software. Each output can be configured individually.

There are two signal types, one for repetitive signals and one for the duration of capture. A typical signal configuration for a repetitive signal allows for a signal at frame rate or multiples and sub-multiples of the Vicon system capture frame rate to be set up. A duration event allows the signal to be active during the capture period. Both signal type setups allow for a delay of up to one frame to be programmed and the setting of the polarity of the signal. The mark space ratio can be set with the former type. For more information, see Add synchronized output devices to a Vicon system.
