Step 3: Configure the ION Gateway Meter for ModemGate
You need to configure the communications settings on the ION meter that serves
as a gateway.
1. Once the gateway meter is installed and the internal modem is connected, use
the front panel of the meter to configure the internal modem and the serial
communications port.
2. Set the internal modem baud rate, Unit ID and protocol (for most applications
the default settings are appropriate). The baud rate must be the same for the port
hosting the gateway and all connected devices.
3. Set the protocol (on the meter) for the port hosting the gateway to MODEMGATE .
If you have an ION 7300 Series meter select ION as the protocol. The baud rate
for this port must be the same as all other communicating ports.
N OTE
You cannot have MODEMGATE ( ION on the ION 7300 Series meter) protocol enabled on two ports
simultaneously.
