  GENERAL 

 
The VLR-100 is a versatile SMPTE time code LED display, combining high speed SMPTE Longitudinal Time Code (LTC) and 
SMPTE Vertical Interval Time Code (VITC) readers with both an LTC generator and VITC-to-LTC translator. 

 

The LED display characters are 0.56" high and are suitable for viewing across a room.  A brightness control allows adjustment of 
display intensity for use in a darkened environment. 

 

The VLR-100 can display time code or user bits and is optionally available as the VLR-100PC with RS-232 serial interface and 
HORITA TC-TOOLKIT Tape Logging and Control software.  The VLR-100 can be factory upgraded to the VLR-100PC. 

 

The VLR-100 comes standard as a desktop unit and can be installed in a standard 19" rack using an optional rackmount ear kit, or 
can be attached to a wall or other piece of equipment using an optional wall mounted swivel bracket kit.
