AIO600 analog output becomes read-only

[andychang]

hi,

when I try to change (write) one of the analog output channels in MAX, a READ-ONLY message shows up. the range of the channel becomes

0 - 24mA (analog input range) even if I apply a 0-21mA range on the channel.

also, when I manually write the output channels from 0 to 100%, MAX shows the correct values. however, the actual output signal I measured has a high offset with just limited range.

Please help,

Thanks

andy, what hardware are you using?
