Hi-Z Sync and HV Hi-Z Sync I/O Boards Specifications

Applies to Hi-Z and HV Hi-Z sync I/O boards listed in the table on the previous page.
These boards come in a number of pre-engineered systems or can be ordered individually for custom
systems.

Attaching Cables

When attaching video input and output cables, refer to the sheet labeled "AutoPatch Connector Guide"
that ships with the system. The sheet shows where to attach each cable on the rear of each enclosure.
Follow the sheet exactly; the system was programmed at the factory to operate only as indicated on the
sheet. For multiple-enclosure systems, each enclosure will be numbered (e.g., "Chassis 1 of 3") on a
label located on the left side near the power receptacle.
Signals may only be routed from the inputs on a board to the outputs on the same board because each
board has its own switching matrix.
FIG. 30 has examples of cabling sync boards to route the H and V components of the HV sync signal. In
the top example, BNC cables are attached to Output 10 on two Hi-Z sync boards. The bottom example
shows BNC cables attached to the H and V connectors of Output 8 on a single 8x8 HV Hi-Z sync board.
To connect sync inputs and outputs:
1.
Fasten the cables onto the input and output BNC connectors (FIG. 30).

Make sure the sync cable is connected to the correct BNC connector on the correct enclosure. Hi-Z sync
and HV Hi-Z sync boards look similar to standard and wideband (300 MHz) video boards, but the
"AutoPatch Connector Guide" identifies them.
