 QPC841 Quad Serial Data Interface card
Applications
The QPD841 Quad Serial Data Interface (QSDI) card is used to connect the 
switch to a variety of communication devices and peripherals. Any RS-232-C 
compatible device can be connected to any of the four serial ports.
The standard application for the QSDI card is to connect the 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, 
select the dumb mode of operation (Command Recognition OFF, Command 
Echo OFF) before connecting the modem to the asynchronous port.
Serial data interface connector J1 is a standard RS-232-C DB-25 connector 
that connects port 1 of the QSDI card to outside peripherals. Connector J2 is 
non-standard in that it contains the connections for the three remaining serial 
ports (ports 2, 3, and 4), on a single DB-25 connector. An adapter cable must 
be used to connect to standard RS-232-C peripherals. Cables that are 
applicable to the QSDI card are:
SDI male-to-female flat cables (internal module use only)
— NT8D82
— QCAD290
Note: This cable is available in different lengths. Refer to the Equipment

SDI male-to-male round cables (external use only)
— NT8D95 
SDI to I/O cables (system options use only)
