Crystal Vision Introduction 1 Introduction ViPA102 is a 10 bit video proc-amp allowing flexible independent adjustments of a digital signal image in the YUV colour space, essential for correcting transmission errors and colour space or A to D conversion errors.
Crystal Vision Introduction The ViPA102 has one input and two outputs and is based on a 100mm x 266mm module, which fits in all Crystal Vision frames and can be integrated with any boards from the company’s full product range. It uses the RM01 rear connector.
Crystal Vision Hardware installation 2 Hardware installation The ViPA102 video proc-amp is a single height module that fits into all Crystal Vision rack frames. All modules can be plugged in and removed while the frame is powered without damage. 2.1 Rear modules and signal I/O The Indigo 4 4U frame will house up to 24 single height modules with up to three power supplies.
Crystal Vision Hardware installation 2.2 ViPA102 configuration The jumper links on the board are set correctly when ViPA102 is tested before despatch and should be left as set at the factory. The following information is for jumper position confirmation only.

Factory reset The factory reset check box may be used to apply a factory reset to the ViPA102 module restoring the factory defaults to all parameters. This is a convenient way to re-initialise the board in the unlikely event of any suspected malfunction.
6 Trouble shooting Card edge monitoring Once the start-up initialisation procedure is complete, the ViPA102 card can be controlled or configured from active control panel or the Statesman PC interface. Although operation from the card edge is not possible status information is supplied at the card edge from a number of LEDs.
If necessary re-set the card by simply removing the rack power and re-applying power after a few seconds or by removing the card from the rack and then re-inserting the card It is safe to re-insert the card whilst the rack is powered ViPA102 User Manual R1.2 04/07/2007...
