Software service changes
Once the NT8D841BA QSDI paddle board has been installed in the
system, the system software needs to be configured to recognize it, using
the Configuration Record program LD 17. Instructions for running this
program are found in Software Input/Output Reference — Administration
(NN43001-611).
Some of the prompts that are commonly used when running the
Configuration Record program LD 17 are shown in
. These parameters must be set for each port if both ports
are being used.
Applications
The NT8D41BA Quad Serial Data Interface paddle board is used to connect
the Meridian 1 switch to a variety of communications devices, printers, and
peripherals. Any RS-232-C compatible device can be connected to either of
the card’s two serial ports.
The standard application for the paddle board is to connect the Meridian
1 switch to the system console. This can be either a direct connection
if the console is located near the switch, or through a modem for remote
maintenance.
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 NT8D41BA QSDI paddle board cabling.
