Configuring the channel input mode

The counter inputs are configurable as single-ended (±12 V ) or differential (±12 V; differential input ±14

Vmax) mode via on-board switches (see Figure 1).

Figure 1. Channel input mode switch

Figure 2 shows the locations for the counter input mode switches and the counter LEDs. Using the board

orientation shown in Figure 2, slide the switch to the left (toward the USB connector) for single-ended mode, or

to the right (towards the 37-pin connector) for differential mode. Note that the "dot" is visible on the switch

when configured for differential mode, regardless of the board orientation.

By default, the board is shipped with the counter inputs configured for single-ended operation (as shown in

Figure 2).
