Hello there!
I have a device that uses SN65HVD3082ED as a RS485 transceiver to exchange data with my product, which sometimes uses transceivers from others companies (like MAX485). My product acts like a controller and the device as a peripheral, there's no other device on the same line. The problem is, the device receives a data request correctly, but my product don't receive the response (or any data). Using some cheap RS485-to-USB converter, the communication between PC and the device is flawless. Also my product is working fine, because it communicate with several third party devices without any problem! So I'm totally lost of what's going on... The picture below shows "inside" both hardwares:
Does anyone know what's going on here?
Thanks a lot!
