Control Cables
Most control cables must be built locally. Exceptions include the CAT5
network cables, which are available from third-party suppliers, and certain
RS-422 serial control cables, which can be purchased from Grass Valley.
44-pin Control Connectors
Pinouts for 44-pin control connectors are shown in Table 9 . For Dolby E
