2.7 Jumpers Description
The 7248/96 DIO cards are Plug and Play, thus it is not necessary to set up
the card configurations to fit the computer system. However, to fit different
users’ versatile operating 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 7248/96 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.

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 use 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)
