Cabling

Note

At the back of this manual (hard-copy only) are die-cut overlay cards that can
be placed over the rear connector BNCs to identify the specific 8990ARC con-
nector functions.

Loop-through Input

Connect an input source to one of the loop-through input connectors, J9 or
J10 (see

Figure 3

). The 8990ARC input accepts SMPTE 259M-C or EBU tech

3267 8- or 10-bit component serial digital video. Terminate the unused con-
nector into 75

if the signal is not looped to other equipment.

Figure 3. 8990ARC Input, Output and GPI Connectors

Outputs

The 8990ARC provides four 75

component video output BNCs (J1

through J4).

The destination equipment should have a 75

input impedance or loop

through inputs that are terminated into 75

.

General Purpose Interface (GPI) Connections

BNCs J7 and J8 accept GPI control signals that select one of four
user-defined preset settings that are stored using the onboard configura-
tion controls or the remote GUI controls. The GPI can be used with a
user-provided panel with four latching momentary switches and appro-
priate resistors. No tally is provided from the module.
