Hallo. adapter rs 232

we can’t see adapter rs 232 whis xctu. can you answer why? please!we have a converter rs 232-usb and driver. but it did’t work.

When you connect the adapter, did you get COM port?
Does your PC recognize the device?

yes when we connect the adapter we get com port.
no our PC didn’t recognize the device

We have connected power supply unit to the adapter, first time ASSC indicator was blinking, we thought that it was connected to the network. and now it does not flash, what does it mean? signal is still not amplified.
