2.1.2 Digital Video

Digital video-signals are fed in via the 64-pin connector X3. Total 32 databits, two frame-data-valid and two line-

data-valid signals and two pixel clocks (max. 40Mhz.) can be supplied by the connected cameras. Four single-ended

TTL-signals control the camera. These are the same sgnals as are connected to the analog connectors.

The (optional) RS-422 (Type Nr. M422) line-receiver board converts the differential lines to single ended TTL

signals. Fast (80Mhz), low threshhold line-receivers are used. A flat-ribbon cable connects the M422 with the

INSPECTA.

2.1.3 Camera-simulator

For testing purpose a camera simulator is provided. The simulator generates a greyscale with RS-170 or CCIR timing.

Video data is derived from the horizontal counter.

2.1.4 Opto-coupled I/O

External signals are connected via four opto-coupled inputs and four opto-coupled outputs.
