Installation

Cabling

8937 Module

Refer to Figure 5 for cabling the 8937 module. Cabling to and from the

module is done at the back of the Gecko 8900 video frame or on the corre-

sponding 89000V-R rear module of the GeckoFlex frame as described

below.

Loop-Through Input

One serial digital component input is provided at differential loop-through

BNCs J9 and J10. If the unused input is not looped to another device, it

should be terminated in 75 ohm.

Outputs

There are eight outputs for the 8937 module at BNCs J1 through J8. Output

destination equipment should have an input impedance of 75 ohm unless

it has loop-through inputs, in which case the loop-through inputs must be

terminated into 75 ohm. All outputs are in phase with the input signal.
