OTSC CR - sensors with S8 not recognized

[plazma]

I have an S8 cable connected to sensors or 50mV test voltage (made by lab PSU and voltage divider).
The CR still shows only 0.0mV for each sensor.
Mode is set to sensor. S8 input is set to analog.

I measured correct 50mV test voltage at the end of the S8 cable.
When S8 cable is connected to the CR and sensors are disconnecgted, then I can measure 100k ohm resistance between sensor molex connector + and 1 pins. CR got inernal 100k loads.

The S8 cable and connectors are clean and corrosion free.

I also tested firmwares 3.21, 3.24-3.26.

Has anyone else had such a problem?

UPDATE: I flashed the latest 3.26 firmware and it works now.

Hi,

Thanks for the feedback.

If someone sees this post: the most likely issue is that you need to install the firmware including the external sensor functionality.

For English and the 3.26, it's called "326_EN_3_cr_ostc3_firmware.hex".
