GPIB Bit4886 reads but does not write

[HAM1450]

Hi All,

So I am trying to use a Kepco 100-4 to power a small magnet. The Kepco connects via GPIB to a bit4886 interface card. We can communicate with the Kepco through NI Max, but not LabView. (We have used this model of power supply for years) In NI Max, we can use the 'measure' commands to read both current and voltage outputs of the power supply but cannot write to the power supply. 

Does anyone have any ideas why this could be the case? I believe it's related to termination characters in the write commands but am not familiar with the software side yet.

Best,
