This White Paper is not meant to be an exhaustive step-by-step discussion in configuring the
RUI/Gateway, for this work has already been done in two other published EZ-ZONE
manuals. For instance, if needing assistance in setting the RUI/Gateway IP (Internet Protocol)
address or if you are simply looking for general information pertaining to Modbus
used with EZ-ZONE
(http://www.watlow.com) and download the EZ-ZONE
or the EZ-ZONE

Prior to looking closer at the RUI/Gateway configuration prompts let's first take a look at the
network in use.
