1104 QPC841 Quad Serial Data Interface card
•NT9D11 Core/Network module (slots 0 through 8)
Note: When a QSDI card is installed in an NT6D60 Core module, an
NT8D34 CPU module, or slot 13 of an NT6D39 CPU/Network module in
a dual-CPU system, any input/output I/O device connected to the card
does not function when the CPU in that module is inactive.
Physical description
The QPC841 QSDI card is a printed circuit board measuring 31.75 cm by
25.4 cm (12.5 in. by 10 in.). The front panel is 2.54 cm (1 in.) thick. See
Figure 314 "QPC841 QSDI card front panel" (page 1105).
Up to four QSDI boards can be used in a system, allowing a total of sixteen
asynchronous serial ports. The four serial ports on each card are addressed
as two pairs of consecutive addresses (0 and 1, 2 and 3, and so on up to 14
and 15). The pairs need not be consecutive. For example: pairs 0 and 1,
and 4 and 5 could be used.
The card front panel has two connectors, J1 and J2. Connector J1 is used
for port 1 while connector J2 is used for ports 2, 3, and 4. It also has an
Enable/Disable (ENB/DIS) switch and a red LED.The LED indicates that
the card has been disabled. It is lit when the following occurs:
•the ENB/DIS switch is set to DIS
•all of the ports on the card are disabled in software
•none of the card ports are configured in software
