Software Configuration
• In Multiport Settings:
• Select the Multiport radiobutton.
• In SISR base box, enter a SISR value of 0104 (this
value was returned by the BBCARDS program, as
described in the above section.)
• In the Card's Port field enter a value of 1, as this is the
first port of the PCI Quad RS232 installed.
• In Standard Settings:
• In the COM Base field, enter the value 0140 (this value
was returned by the BBCARDS program, as described
in the above section.)
Note: COM ports are defined with an i/o address range,
which in this case, begins at 0140 and all subsequent
ports have an i/o address that is 8 higher than the
previous. i.e. if COM2 has an address of 0140h, then
COM3 will have an address of 0148h, COM4 an
address of 0150h etc.
• In the IRQ field, enter the value 11 (this value was
returned by the BBCARDS program, as described in
the above section.)
• When you have finished, click on OK. A restart message will
be displayed; to save only restart when all four ports have been
added and correctly configured.
• Repeat the above process to add the next 3 COM ports of the
PCI Quad RS232. For example, for the second port of the PCI
Quad RS232 (designated COM3) the SISR value of 0104 will
remain the same, the Card's Port value will be 2 (the second
port of the Quad card), COM base will be 0148 and the IRQ
value is 11. After adding the remaining COM ports the COM
Ports Window will look similar to the following:
