Lock Lab is a connectivity device from Vicon, offering a cost-effective and silent solution for providing synchronization and analog to your Vicon Vero and Vicon Vantage systems. Lock Lab features: Support of VESA standards Connection to third-party analog devices Remotely triggered start and stop General Purpose Input and Output (GPIO) sockets for synchronizing external devices Lock Lab front view On the front of Lock Lab, the Vicon logo illuminates to indicate status. Color Status Red Booting Green Booted but not connected Blue Communicating with software Cyan Lock Lab selected in software Note Images are included in this guide for representative purposes only; details may be subject to variation and all principles of operation are as described. Lock Lab rear view  Analog inputs: 8 x connectors, 64 channels  Link input/output (I/O)  PoE  Earthing (grounding) point  VESA sync input  Remote Control input start and stop  GPO sync outputs (x8) Connection details The rear panel contains these sockets for capture and synchronization (from left to right of the unit):   Analog inputs . Require the supplied Weidmüller connectors, with total analog sample rate of 192 KHz. Lets you connect supported third-party analog devices. For instructions on using the connectors, see  Connecting analog devices to Lock Lab . Lock Lab provides 64 channels for generating 16-bit offset binary conversions from analog sources. The input impedance is 1 MΩ. The data sampling frequency is common to all channels; you can set the sampling rate to be a multiple of the camera base rate up to 192,000 samples/second (192 KHz). The capture frequency you can specify depends on the total number of channels to be sampled, as shown in this table. Number of channels Max. frequency (KHz) 1 192 2 96 4 48 8 24 16 12 32 6 64 3  Link I/O . Provided for Lock-to-Lock synchronization. Also provides Lock Lab-to-Giganet synchronization. Connect to Vicon equipment only.   PoE  (conforms to IEEE 802.3af). Requires connection to a Gigabit (Ethernet 1000BASE-T) PoE switch. Use only the supplied cable.   Earthing point . Always ground the Lock Lab using this dedicated earthing point. Important : The earthing point is provided to solve ground loop issues that can degrade signal quality on connections to third-party equipment. It is not intended for earth safety.   VESA sync input . 3-pin mini DIN socket. Current Vicon software supports 100Hz and 120Hz. After it is locked, Lock Lab can be phased with respect to this input signal in increments of 18 nS through a whole frame period.  Remote Control input start and stop . RCA phono sockets for connecting a remote third-party device that triggers the Vicon camera system to capture data based on input signals. Start and stop are activated on next frame boundary. Requires connection to GND (ground).  Eight standard programmable phono (RCA) sockets for synchronizing external devices using General Purpose Output (GPO) signals. To manage the synchronization of your external devices, or to trigger your external devices based on Vicon system events, identify an appropriate GPO configuration file supplied with your Vicon software or create your own GPO file (for details, see the  Vicon Systems Setup Guide ). In your Vicon software, specify this GPO configuration file for your external device.  Caution : The analog inputs are very sensitive and therefore susceptible to external interference via the PoE connection and other equipment that emits electromagnetic interference. To ensure such induced noise is acceptable, look at the resultant reading with a static input. For example, verify that a static force on a connected force plate shows an acceptable amount of ‘jitter’ on the resultant force vector. If it exceeds an acceptable limit, reduce induced noise on the analog inputs to an acceptable level by ensuring: a) connected wires are shielded and the provided ground signals are used, b) the Lock Lab case is earthed to a clean grounding point using the provided earth stub, and c) other interference sources are disconnected or otherwise isolated.
