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 
ION Enterprise 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: 

Refer to the EtherGate technical note for complete details on configuring your 
meter for EtherGate.

The 9350 appears in the 

Devices list, because it 

must be configured as an 

Ethernet device before you 

can configure it as an
