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 on cards for frames that include output options 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.
