Connecting to the por ts
External devices are connected to the SDI/DCH card by the following:
•
the NTAK19FB four-port SDI cable. This cable does not have to be
terminated at the cross connect terminal since it is equipped with
connectors.
•
the NE-A25-B cable. Terminate the NE-A25-B cable at the cross
connect terminal. Tables Table 339 "NTAK02 pinouts - Port 0 at the
cross-connect terminal" (page 851) through Table 342 "NTAK02
connections at the cross-connect terminal - Port 3" (page 852) give
the pinouts for the SDI/DCH card.
