problem with my FP-AI-110

[Frenchy]

Hello,

I use one FP-AI-110, where I acquire of a signal in voltage (channel 0, on Vin and COM).

My problem is that on the FieldPoint software, all the channels of acquisitions give me the value of the signal which I connected on channel 0.

I cannot thus connect another signal in voltage on channel 1.
How can I make?

thank you
sorry for my English

Frenchy, Are the other inputs connected to anything? It sometimes happens that open circuit high impedance inputs will follow the signal of an adjacent channel. This is kind of like "crosstalk" but crosstalk can only be measured between properly terminated signals, so it is not really crosstalk. Try connecting the other channels to another signal source or place a resistor across their input and see if the other channels stop following channel 0. This also happened to me about 10 years ago with an ISA bus MIO board.
Good Luck
