12 PCI-1720 User's Manual

The PCI-1720 is a “plug-and-play” 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

configure to your applications requirements. The following sections

offer the necessary information for setting the PCI-1720’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-1720 output voltage range

to 0 ~ 5 V. The figure below shows the correct jumper settings for the

PCI-1720’s current sink range.
