Device does exactly what it is supposed to. Converts from RS232 to RS485 modbus. No speeds to set or configure. They do have a nice jumper option to reverse the Send/recieve which can be handy.

I've used these a few times now in access control and parking environments where I have an rs232 device in a remote location. My uses have been door controllers in remote locations and hotel room key systems for connectivity to parking systems. Seems to work perfectly anywhere you have a computer and an rs232 device that need to talk to each other over a long distance.
