The BNC-2090 terminal connector is designed for use with the BNC-2090 and a 50, 68, or 100-pin MIO DAQ board or a 50-pin PC-LPM-16 DAQ board. The BNC-2090 can be set in three different modes for application specific measurements, but all channels must be configured for the same mode. These modes are differential, nonreferenced single-ended (NRSE), or referenced single-ended (RSE). This information can be found in Product Manuals: BNC-2090 User Manual . (The BNC-2090A can be configured to read different channels in different modes.)The BNC-2090's green-and-orange terminal strip provides access to the DIO and counter/timer features on the E Series boards. The terminal strip "GND" does not reference the AIGND on the DAQ card. Instead this GND is tied to the shield of the connector to the DAQ device. An internal jumper determines the resistance between the GND terminal and the shield. The default setting is 100 Ω, but it can be changed to 0 Ω or open by setting a jumper inside the BNC-2090.
