Hi to all,

here a screenshot of output signal to RUT955 serial port:

echo "55" > /dev/rs232

Ground to pin 5, signal on pin 2.

Shouldn't it be bipolar and not 0-12V?
Thanks.

Hello,

Thank you for reaching out.

I do not have an oscilloscope to test it, so I will reach out to our RnD department to clarify if this is the intended behavior.

Before I do, please provide the serial number of your device for traceability via a private message.

Also, does this cause any issues in your setup, or have you just observed this behavior?

Best regards,

Goodmorning,

I have not available serial number on the fly.
I was just making some tests on serial port on default (factory) configuration to be sure about serial port pin configuration and adapters to be used to connect my hardware.
This was just a:

echo "55" > rs232

command.

I made same test on different RUT955, same factory configuration, and I got bipolar signal, as expected.
I'll send you serial number asap.
Regards, Michele.

Hello,

Perhaps you have the serial numbers available?

I will ask you to send both serial numbers - for the device that behaves as expected, and the one with a non-bipolar signal. Thank you.

Best regards,
