2.7Jumpers 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.

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’

2.Port A of CN1 are power-on pulled low. ‘L’
