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.

JA2 P2A JA4 P4A

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.
