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)

1 2 JA1

1 2 ... 22 23 24 25 26 27 28 29 30 31 32 ... 58 59
