8901/8902/8906 Instruction Manual 15
Installation
8800 Frames
The 8800 frame provides the same looping BNC analog input with eight
outputs (
Figure 3 on page 13 ). Remote control with the 8900NET module is
not available in the 8800 frame.
Cabling
Refer to Figure 6 for cabling the 8900 Analog Video DA module in an
8900/8800 frame. Only the first six outputs are available when a module is
installed in the 8500 frame. Cabling to and from the module is done at the
back of the video frame as described below.
Note At the back of every hardcover manual are overlay cards that can be placed
on the rear connector BNCs to identify the specific connector functions.
Loop-Through Input
One analog video input is provided at loop-through BNCs J9 and J10. If the
unused input is not looped to another device, it should be terminated in
75
Ω .
Outputs
There are eight outputs from each 8900 Analog Video DA module at BNCs
J1 through J8. Output destination equipment should have an input imped-
ance of 75
Ω unless it has loop-through inputs, in which case the
loop-through inputs must be terminated into 75 Ω .
