        The monochrome video output levels are ECL/TTL, with a
        resolution of 1152 x 900 at 61.8KHz horizontal sync and 66Hz
        vertical sync. The pinout of the monochrome video connector is:

            1   VIDEO+              6   VIDEO-
            3   HSYNC               7   GND
            4   VSYNC               8   GND
                                    9   GND
You simply need a 1:1 DE9 cable. If the cable is longer then maybe 1'
use a twisted pair for the two video signals. (E.g. Use a CAT5 Ethernet
cable and solder the two wires of a twisted pair to pins 1 and 6. An
other pair to pins 3 and 7 and a third to 4 and 8.)

Extron? URL?

Just use a simple "VGA-BNC" cable. there is no magic in that cable. It
just breaks out R/G/B/H/V from the DE15 VGA to individual BNC
