Video Inputs

Four pairs of BNC connectors (1-5, 3-7, 2-6, 4-8), located on the rear
panel, are used for video inputs to the SuperQuad (see Figure 3, page
3). All video inputs must be RS-170 standard, 2:1 interlaced,
composite video signals.

The camera video connected to a particular BNC is automatically
assigned to the corresponding on-screen camera number. That is, a
camera connected to BNC 1 is automatically assigned to the on-screen
camera number 1, a camera connected to BNC 2 is automatically
assigned to the on-screen camera number 2, etc.

Each pair of BNC connectors is associated with one quadrant of the
Quad format display, as indicated by the legend above each slide
switch. Camera 1 or 5 is displayed in the upper left quadrant, camera 2
or 6 is displayed in the upper right quadrant, etc. Refer to Figure 4
below for illustration of the Quad formats.

Four video inputs make up one Quad display. Video Inputs 1 thru 4
are displayed in Quad A; video inputs 5 thru 8 are displayed in Quad
B. Refer to Figure 4.

Four 3-position slide switches located on the rear panel, one under
each pair of BNC connectors, configure the input termination of each
pair in one of three ways: LOOP 75, DUO, or Loop HiZ.

LOOP 75 

- Internally loops the video from the lower numbered BNC

to the higher-numbered BNC of the pair. The lower-number input
BNC is terminated in 75 ohms. The higher-number BNC must not be
used.

QUAD A

QUAD B

Figure 4 - Quad A and Quad B Formats

Typical configurations of video inputs using these connections
are shown in the Appendix.

Figure 5 - LOOP 75

DUO - Separates each input BNC pair, terminates each input in 75
ohms, and makes them independent video inputs. Both BNCs of the
pair may be used as separate inputs.

Figure 6 - DUO

LOOP HiZ 

- Same as LOOP '75, except the lower-number BNC

is unterminated (HiZ). The higher-number BNC must be looped to a
properly terminated external video device.

Figure 7 - LOOP HiZ

Each input pair of connectors may be set for a different termination.
Any combination of the above settings is valid on ;she four pairs of
inputs as long as each input is properly terminated
