SDI ports

The minimum system port configuration for Option 11C Mini is 3 SDI ports, all of which are on the NTDK97 MSC card.

You can get additional ports by installing an NTAK02 SDI/DCH circuit card. The SDI/DCH card has 4 serial I/O ports with three possible configurations:

2 asynchronous ESDI ports with 2 DCHI ports

2 synchronous ESDI ports

2 SDI ports

Table 83 shows the default SDI port configuration. The value for “XX” is set on the faceplate of the MSC circuit card.
