The EtherGate Protocol
EtherGate is a powerful communications tool that lets you communicate to a meter
and through a meter simultaneously. When a meter installed on the Ethernet
network has EtherGate enabled, a master device (such as a workstation running
IONE nterprise software) can communicate to the meter, as well as through the
meter to a serial network of devices wired to the meter’s COM 2 port.
EtherGate is only available for the 9330 and 9350 meters, and it is only configurable
on the COM 2 port. (Port 7802 is used for EtherGate communications.)
Once you have the chain of serial devices installed, use Designer or the meter’s
front panel to change the COM 1 or COM 2 Protocol setting to EtherGate. The
transfer of data between protocols is then handled automatically.
The Devices list in the Management Console appears as follows:

The Gateway Site - set the IP Service Port to
7802 for COM 2. The number following the
IP Service Port number is the device’s unique
Unit ID.
The 9350 appears in the
Devices list, because it
must be configured as an
Ethernet device before you
can configure it as an
Ethernet Gateway Site.
From the Type heading in the
Sites window, you can see the
9350 has been configured as
an Ethernet Gateway Site.
