Question: I am trying to set the port number to 65535 but the DS100/EM100 wouldn't let me do this! Why is that?
Answer: The DS100/EM100 has two logical ports - a Data Port and a Command Port. The Data Port is used to exchange the serial data between the DS100/EM100 and the remote station (PC, another DS100, etc.). Command Port is used to setup the DS100 via the Network. The Data Port number is user-definable and can be in the range from 0 to 65534. Command Port number is fixed at 65535. This is the reason why you cannot set the Data Port number to 65535.
