на любые трансиверы. Иногда рандомно начинает работать нормально. Смена портов, компов не помогает.
The transceiver didn't response on address byte with read instruction. It keeps silence. This error appears when you read unavailable page or transceiver is not working. If you got QERR:R20 on reading Table A2, it mean that module doesn't have Table A2 and doesn't support DDM which presented in this address space.
