738 NT8D41BA Quad Serial Data Interface Paddle Board
Bell 103/212 compatible dumb modems are recommended to connect
a remote data terminal. If a smart modem (such as a Hayes modem) is
used, configure the modem for the dumb mode of operation (Command
Recognition OFF, Command Echo OFF) before connecting the modem to
the asynchronous port.
The serial data interface connectors on the paddle board are not RS-232-C
standard DB-25 connectors. The NT8D84AA interface cable is used to
adapt the paddle board to a non-standard pinout DB-9 connector (normally
located on the I/O panel). The NT8D93 cable is then used to connect
the non-standard DB-9 connector to a peripheral that uses a RS-232-C
standard DB-25 connector. See
Figure 248 "NT8D41BA QSDI paddle
board cabling" (page 730) .
