The DSAN VC-2000 Video Clock is a Cat 5 to USB dongle that passes serial data from a DSAN speaker timer or cue light to the included PC-hosted companion software. The software configures the data according to user-controlled parameters of size, color, background, position, and transparency. Included or user created bitmaps simulate green-yellow-red phase lights. The output may be displayed alone or on top of other applications such as PowerPoint. The Video Clock requires data from PerfectCue, Limitimer, or The TimePrompt, which must be purchased separately.
