Chapter 3 Jumpers and I/O Connectors

The PCI-1720U is a Plug & Play compatible card, i.e. the system BIOS

assigns the system resources such as the base address and the interrupt

number automatically. There are only 2 functions with 5 jumpers to con-

figure to your applications requirements. The following sections offer the

necessary information for setting the PCI-1720U’s jumpers. You may

need to refer to the figure below for help in identifying jumper locations.

3.1 Jumper Settings

3.1.1 Using Jumpers to set Current Sink Ranges

Jumpers JP1 to JP4 are used to select each channel’s current sink range,

either 4 ~ 20 mA or 0 ~ 20 mA. Jumpers JP1 to JP4 correspond with D/A

channel 0 to channel 3 respectively. In order to use the current sink

range, you have to set the PCI-1720U output voltage range to 0 ~ 5 V.

The figure below shows the correct jumper settings for the PCI-1720U’s

current sink range.
