DIO7 of PCI-6024E forgets input/output setting?

[magyarmagyar]

encoder pulses fed to PCI-6024E DIO7 (used as up/down input) to GPCTR1; after a few days DIO7 loads down the encoer signal, dropping the voltage. It seems that the DIO line is not switched to INPUT mode. MAX thinks it is and input but the DIO hardware does not behave like it. Anyone had this problem? Any solutions?

No, this isn't something that is a known issue. It might not be that the DIO line is loading down the encoder. There might be a problem with the encoder itself. To check this, do a continuity/Ohm check between DIO7 and ground.
