2.7 Jumpers’ Description
The PCI-7396 is a ‘plug and play’ add-on card using PCI bus. It is un-
necessary for user to setup its base address and IRQ level to fit the
hardware of your computer system. However, to fit users’ versatile operation,
there are still a few jumpers to set the power-on-states of all I/O ports.
2.7.1 Power-on-state
For all I/O ports of the PCI-7396, the power-on-states could be pulled high,
pulled low, or floating. It is depended on the jumper settings. Table 2.1 lists
the reference numbers of jumpers and their corresponding port names.
Jumper Port Name Jumper Port Name
JA1 P1A JA3 P3A
JB1 P1B JB3 P3B
JC1 P1C JC3 P3C
JA2 P2A JA4 P4A
JB2 P2B JB4 P4B
JC2 P2C JC4 P4C
Table 2.1 Jumpers and port names list
All the jumpers are identical physically. The power-on-state of each port can
be set independently. To pull all signals low is the default settings. The
following diagram use JA1 as an example to show the possible settings.
Port A of PPI1 is pulled low.(default setting)
Port A of PPI1 is pulled high.
When the jumper cap is removed, the power-on-state is floating.
