Installing and connecting SDI ports
NTMW01 SSC
The baud rate for port 0 is controlled by a switch setting on the circuit card’s
faceplate. Ports 1 and 2 are user configurable using overlay program 17.
•
Port 0 is the only SDI port that can be used for software installation and
upgrades.
•
All three ports on the SSC card can be used to connect terminals.
•
Modems should only be connected to Port 0 since it is the only port that
supports Carrier Detect (CD).
•
An NTBK48 3-port SDI cable must be used with the NTMW01 SSC
card.
Note: The default baud rate of the SSC card is 19200 bps. When
changing the DIP switch on the faceplate, make sure only one baud rate
switch is set to ON (Refer to Table 13).
describes how to connect a terminal, modems and
other devices such as CDR devices and additional TTYs to the SSC card.
