2.7 Jumpers Description
The 48H/96H DIO cards are ‘plug-and-play’, thus it is not necessary to setup
the card configurations to fit the computer system. However, to fit users’
versatile operation environment, there are still a few jumpers to set the
power-on status of ports and the usage of the +12V output pins.
2.7.1 Power on Status of Ports
For every port on the PCIDIO 48H/96H cards, the power-on status is set as input,
therefore, the voltage could be pulled high, pulled low, or floating. It is
dependent on the jumper setting. Table 2.1 lists the reference number of
the jumpers and the corresponding port names.

J C4 P4C (Port C of CN4) for PCIDIO 96H
Table 2.1 Jumpers and Port names list
The physical meaning of all the jumpers are identical. The power on status
of each port can be set independently. The default is to pull all signals high.
The following diagram uses JA1 as an example to show the possible
configurations.
1. Port A of CN1 are power-on pulled high. ‘H’
1 2 JA1
2. Port A of CN1 are power-on pulled low. ‘L’
1 2 JA1
3. Port A of CN1 are power-on floating. (The jumper is removed)
