Building on the success of the GSI-1 and GSI-2 tally controllers, the GSI-3 adds UMD support, as well as an expanded matrix size.  The user can create a GPI routing matrix up to 240 x 240.  The GSI-3 provides a serial interface to popular production switchers, such as GVG4000, SONY MVS-8000, Thomson Kalypso, and DD35
