We are testing the ADM2587E for a new product and we encountered some communication errors with baud rate 9600 and bus of short distances (<3m) with no termination resistor. We have tried to connect other devices to the bus, managing to communicate correctly with all the device except with the device with the ADM2587E. With the termination resistor the situation is better but we are losing still 10% of the sent packets. We use a Moxa Transio A52 Smart Converter 232/485 converter for the communication with the PC.
Suggestion or advice to solve this issue?
