Lock Studio is a connectivity device from Vicon, offering a cost-effective and silent solution for providing synchronization and timecode to your Vicon Vero and Vicon Valkyrie systems (Vicon Vantage is also supported). Lock Studio features: Timecode and genlock, including genlock to SD, HD and 3G SDI broadcast digital video signals, and extracting timecode metadata Support of VESA standards Remotely triggered start and stop General Purpose Input and Output (GPIO) sockets for synchronizing external devices Sync to SteamVR for use with HTC Vive Lock Studio front view On the front of Lock Studio, the Vicon logo illuminates to indicate status. Color Status Red Booting Green Booted but not connected Blue Communicating with software Cyan Lock Studio 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 Studio rear view  Link input/output (I/O)  PoE  Earthing (grounding) point  SDI input  Analog video reference input including VITC  Timecode input: LTC   VESA sync input  Timecode output: LTC   VESA sync output  Remote Control input start and stop  GPO sync outputs (x8) Connection details  Link I/O . For Lock to Lock synchronization. Also provides Lock Studio to legacy Giganet synchronization. Connect to Vicon equipment only.   PoE  (conforms to IEEE 802.3af). Requires connection to a Gigabit (Ethernet 1000BASE-T) PoE router. Use only the supplied cable.   Earthing point . Always ground the Lock Studio 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.   SDI (Serial Digital Interface) input . Fixed 75 Ω terminated BNC input for connecting to Standard Definition (SD), High Definition (HD) and 3G SDI broadcast digital video signals. Used to genlock to external video broadcast signals and to extract embedded timecode data. Lock Studio can be phased with respect to the selected input broadcast signal in increments of 37 nS through a whole frame period. For more information, see  Vicon Lock genlock support information .  Analog video reference input, including VITC. Dual BNC sockets for connecting an external video source that transmits a composite video signal, including Vertical Interval Timecode (VITC), from the master video source to the Lock Studio and any other synchronized video or audio devices in a chain. The Lock Studio must be genlocked to this external video source. Important : If the Lock Studio is the only device or the last device in a chain, the Ref Loop connection that is not used for signal output must be terminated in 75 Ω remotely or by using a 75 Ω terminator. Note:   When inputting HD tri-sync standards (such as Film, NTSC Film, and 30 fps), LTC is required for timecode.  Timecode input: LTC . XLR socket for connecting an external source that transmits LTC (Longitudinal Interval Time Code) to the Lock Studio. LTC is supported at 23.98, 24, 25, 29.97 and 30 fps. Requires an accompanying synchronized genlock source: see  Vicon Lock genlock support information .   VESA sync input . 3-pin mini DIN socket. Current Vicon software supports 100Hz and 120Hz. After it is locked, Lock Studio can be phased with respect to this input signal in increments of 18 nS through a whole frame period. Also used for sync and connecting with HTC Vive via SteamVR.   Timecode output: LTC . BNC socket that enables output of a single-ended LTC signal (23.98, 24, 25, 29.97 and 30 fps) through a 100 Ω resistor.   VESA sync output . BNC socket. Current Vicon software supports 100Hz and 120Hz.This output signal can be phased with respect to the system sync (including the sync to Vicon cameras) 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 system to capture data based on input signals. Start and stop are activated on next frame boundary. Requires connection to GND (ground).   GPO sync outputs . Eight programmable phono (RCA) sockets for synchronizing external devices using General Purpose Output (GPO) signals. To manage synchronization of external devices, or to trigger them from Vicon system events, identify an appropriate GPO configuration file supplied with your Vicon software or create your own (see the  Vicon Systems Setup Guide ). In your Vicon software, specify the GPO file for your device.
