20. When do I need to use an EDS (electronic data sheet) file for a 1782-JDMx gateway?
An EDS file is not necessary, but it makes configuring the 1782-JDMx (changing baud rate, framing, etc.) far easier than if you were to try to change the device parameters by editing the attributes of certain class objects and instances without the aid of a configuration tool. There are many software configuration tools available with EDS readers that can be used to set up the device.
