1.5.1 VGA Connector
The graphics board analog output is provided on a standard VGA style
compressed 15 pin D-Sub. Alternatively, when the DVI-I connector is
used (see Section 1.5.2), an adapter (Molex 88741-8700) can be used to
supply analog video to a standard VGA computer side connector.
In either case, an "Autoscan" type monitor is used. You must use the
correct initialization, since a VGA monitor depends on the sync polarities
to determine operating frequency. The polarity of the Vertical/Composite
Sync and Horizontal Sync are controlled by the Borealis graphics
controller chip (see Section 4.5). See the Note in Section 2.9.2
concerning composite sync on green and RGBHV video out modes. If
you have problems, please contact Rastergraf for assistance.
The R, G, and B video outputs are driven by the Borealis graphics
controller chip which is capable of driving terminated cable (75 ohms) to
standard RS-330/IRE levels. Cable length should be limited to 50 feet
unless you use low loss RG-59.
Rastergraf has used an outside cable shop to build production cables:
Lynn Products, Inc.

If you really want to roll you own, the PMC board side connector is an
AMP 177802-3. The CompactPCI and PCI board side connector is an
Adam-Tech HDL15-SLB. Be sure to use 75 ohm coax for the R, G, B.
You can use TP or coax on H, and V. A cable that would work is Mogami
W3206-8 (http://www.mars-cam.com/ccd/mogami/digital3.html).
