Issue Details

I am using two BNC-2110 terminal blocks for digital input or digital output with my M Series DAQ board. The installation instructions do not explicitly state that my device is compatible with the BNC-2110, and there are more outputs than listed on the breakout box. What are the corresponding pinouts and where are all the digital outputs available?

Solution

The following table lists which pins are accessible through each BNC-2110 connected to the M Series Device:

F OUT / FRQ OUTP0.30 (pin 1)

Keep in  mind that not all outputs are available when using the BNC-2110 with M Series Devices. Only 46 of the 48 DIO pins are accessible. 

Also if both connector blocks are used and a counter is required, you must connect to ctr0 on BNC Connector Block 1 using PFI 12 from the M Series Device. The counter output on Connector Block 2 is a digital I/O pin (pin 0.28) and not a counter. ctr1 is a digital I/O pin on Counter Block 1 and on Counter Block 2. 

Signals are verified in reference to any digital ground pin on the BNC-2110.
