We have 2 CSE-H55N2 converters for transmitting RS-485 over the network, for example A & B. Both are configured in U2S-UDP mode with the other listed as a peer. When testing the communication, data will only work in 1 direction - data transmitted by RS-485 connected to A is received correctly by RS-485 on B. However, data transmitted by RS-485 connected to B is not received by A and the RXD light on A never flashes. Since it is RS-485, if it wasn't connected correctly, neither direction would work (send or receive). Since it is working in one direction, it seems like it should work in the other direction.
