ONNECTORS
These Input/output (I/O) BNC coaxial connectors, located on the rear of the unit (see Figure 6) provide
the input/output signal interface.
FIGURE 6: Input/Output Signal Connectors (rear view)
The video input connectors are internally terminated into 75
Ω
. Use coaxial cable and a standard BNC
connector to connect each source. Input and output modules can be populated in increments of 16.
Input modules provide up to 100m (meters) of equalization for HD and up to 300m for SDI. Both
HD/multi-rate and SDI output modules include a single copper connection. However, daughter boards
can be installed to provide a second output per bus. The second output can be either copper or fiber
(single mode or multi-mode). For SDI applications, a DAC monitor grade, 10-bit output board can be
installed as an option. For HD applications, a HD to SD conversion card can be installed as an option.
The Output Slots labeled with “Option” represents an Output Option, which could indicate either dual
output or some other conversion-type slots. (For I/O card removal and installation, refer to Chapter 11.)

SSIGNMENTS
All circuit protection devices (i.e., fuses, current monitoring semiconductors, and temperature circuitry)
for the various cards that are installed in the 64x64 chassis are located on each card and are non-
serviceable by the user.
