PLM-ADIN problem

[camcam85]

I tried to connect the pins 1 and 6 and the measured voltage was 10 V.
I also inserted a resistor of 270 Ohm (the only I have) in the wire and the voltage decreased to 9,94 V.

I haven't understand exactly what do you mean with the second paragraph:
what is the difference between the first circuit with the resistor to test if the card is working?

Something like this? (R= 270 Ohm)

1.jpeg Voltage 1 = 10,00 V

Anyhow, if the problem would be the low load of signal, can this be solved in some way?

Thank you very much!
