BNC connectivity CompactDAQ counter compatibility Individually configurable channel directions The NI 9402 is a digital input/output module for any CompactDAQ or CompactRIO system. You can configure the direction of the channels for input or output on a per-channel basis. Each channel features 1,000 Vrms transient isolation between the channel and the backplane. With CompactRIO, you can use the LabVIEW FPGA Module to program the NI 9402 for implementing custom, high-speed counter/timers; digital communication protocols; pulse generation; and much more. • NI 9402 • NI 9402 Getting Started Guide • NI 9940 Backshell Kit (779567-01) • BNC-to-BNC Male Cables
