Incremental encoders connection and configuration with SDC2130

Good morning
I have just bought an SDC2130 and connect with 2 24v brushed motor, but i can\'t connect the encoder or better, i connect the incremental encoder in the way i think correct but nothing happen.
the encoder mounted on the motor is a TLE4950 with 3 cables.
Ground, +5V and OUT.
i tried to put it in some pinout of the serial connector and tried some configuration but it does\'t work.
I hope that i don\'t misunderstand the datasheet, and so this thread will be useless
thank you for answer

Check that the leds DIN1 DIN2 DIN5 DIN6 in the Run tab of the PC utility change state. This would indicate that the controller hardware sees the encoder signals.
If so, then enable the encoders in the configuration menu. Once enabled, select Counters in the chart and verify that the count changes as you rotate the encoder.
You will need to update the firmware to the latest revision as earlier versions have some problem with encoder operation under certain conditions.

I tried to connect the OUT signal to all the suggested pins but the status led on the PC utility didn\'t change status,However, when I connect it to the pin which is in common to the analog input, this one changes its status in an apparently casual way
by checking out with the tester, I can verify an apparently continuos 5v tension on the output cable. Anyway, this seems to be variable by checking it out with the frequency taster
i tired to upgrade the firmware via usb but the dfu programme crashes in win 7 and in win exp as well

other info:
i have upgrade the firmware via RS232 but it still doesn\'t work.
if I can have some other info about the output signal of the encoder, like testing it with an Oscilloscope, is possible to understand wich is the issue?

When you rotate the encoder you should see the DIN1 DIN2 DIN5 and DIN6 change state in the Run tab.
If not, this means either that the encoder does not output a 5V signal (3V min). Some encoders need pull up resistors.
Otherwise, it may be that the controller\'s inputs are damaged. This is highly unlikely but you can easily test by bringing the 5V signal from pin 14, to the 4 encoder input pins and watch the DIN leds go on in the pc utility

I tried the controller\'s input an they work, the din led on pc utily show me it works and are not dameged.
I tested the encoder out put and that show me a 5v output.
one other info about the Encoder: this is a magnetic one and not optical. I don\'t know if this will be an issue.

The sensor type doesnt matter.
If applying 5V to the input maked the LED go on, then the input works.
If you dont see the LED on when the encoder is connected, this means you dont have 5V going to the input.
There is no other way.
Consider adding a 1K resistor between the encoder output and the +5V on the connector.
