The QSDI paddle board can be used in a system backplane for a total of
four serial ports. Up to 12 other serial ports can be added by plugging
standard serial cards into standard system slots. The serial ports on the
card are addressed as a pair of consecutive addresses (0 and 1, 2 and 3,
up to 14 and 15), using switches SW15 and SW16.
The front edge of the card has four serial port connectors, an Enable/Disable
switch (ENB/DIS), and a red LED. The LED indicates the card status. It is lit
when the following occurs:
• the ENB/DIS switch is set to disable
• all four ports are disabled in software
• all four ports are not configured in the configuration record
