Figure 2-1. PCIM-DAS1602/16 switch and jumper locations

Before installing the PCIM-DAS1602/16 in the computer, verify that the board is configured with the settings

that you want. Review the following information to change the default configuration of a jumper or switch on

the PCIM-DAS1602/16 board.

Board switches are covered by a metal nameplate

To access the Channel Select switch and the A/D Range Select switch, remove the metal nameplate that covers

them. This plate is secured to the board with two screws.

Channel Select switch

Set the channel mode configuration with switch S1. The analog inputs of the PCIM-DAS1602/16 can be

configured as eight differential channels or 16 single-ended channels. Use the single-ended input mode if you

have more than eight analog inputs to sample. Using the differential input mode allows up to 10 volts of

common mode (ground loop) rejection and will provide better noise immunity.

This switch is factory-configured for eight differential inputs. The Channel Select switch shown in is

set to the "8" position. To configure for 16 channels, set this switch to 16.
