The three BNCs are not used on our unit. This is not the frame grabber is
it? Where is the frame grabber located on your machine? I don't easily
see a cable labeled 208. The unit with three BNCs has two multi-pin flat
connector cables labeled 698 and 699. Other cables from the PGT go into
the main SX. Where did you find the 39245305?
