10 8990ARC Instruction Manual
Installation
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
Ω if the signal is not looped to other equipment.
Figure 3. 8990ARC Input, Output and GPI Connectors
Outputs
The 8990ARC provides four 75 Ω component video output BNCs (J1
through J4).
The destination equipment should have a 75 Ω input impedance or loop
through inputs that are terminated into 75
Ω
.
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.
