When EZL-200F sends serial data on RS485 BUS, it doesn'st check if RS485 BUS is using. Of course When EZL-200F doesn'st send serial data on RS485 BUS, it doesn'st hold RS485 BUS. It means if EZL-200F receives data from TCP/IP while some RS485 device sends serial data on RS485 BUS, you may have collision on the RS485 BUS. by the way, is EZL-200F master or slave on your RS485 network?

Those devices must communicate to a computer. The only line between the devices and the computer is a LAN, so i'sve thinking to use the EZL-200F. I'sm doing this test on my lab and i'sm seeing sometimes that we have collision on the 485 BUS (when the device answer collisions with a request from the computer). How could i fix this collision problem?
