See attached ION Knowledge Base article.
The above article details the procedure for adding ION devices to an ION Enterprise system through an EGX100 gateway. This process is necessary due to protocol conflicts. The EXG100 speaks Modbus protocol, where ION Enterprise expects ION meters to speak ION protocol when connecting to them. The exception to this is the ION 6200, which has a native Modbus driver to allow it to speak Modbus protocol to ION Enterprise.
