Vertical Interval Sync Board/Expansion Board
A Vertical Interval Sync board (sync board) gives the Modula complete
vertical interval synchronization switching capability. The sync board
can use a master sync signal by separating sync from an input signal
(such as a composite video input or blackburst).
Each enclosure in a Modula can hold one sync board. You may want a
sync board in each enclosure that switches video signals. If the system
was originally ordered with sync boards, they are already installed in the
enclosures.
Warning: To avoid ESD (Electrostatic Discharge) damage to sensitive
components, make sure you are properly grounded (see the Caution page
inside front cover) before handling any internal Modula materials.
To add a sync board:
1. Make sure all enclosures receiving a sync board are turned off.
2. Remove the plate that covers one of the expansion slots.
