EMTR3 Menu

The Electric Meter Transceiver 3 (EMTR-3) contains the equivalent of network

routing tables that must be maintained. The EMTR-3 maintains a routing table that

is built upon its port list, which reserves a given port for a given Intelligent End

Device (IED). The HHTR-3 can be used to manually create, modify, or remove

these port list assignments.

There are two options for inserting an IED into the EMTR-3’s port list: Listen

Mode and direct access to the Port List. Both options provide the same installation

with different aspects of the process being automated. Whether automated or

manual, the process gathers the IED serial number, service type, and desired port

location for installation.

The user must know the serial number of the EMTR-3 and manually enter it into

the HHTR-3 to establish a communication link with the EMTR-3.

OTES

When entering an ORION gas or water IED serial number for installation, if the

serial number is less than 79,999,999, drop the first digit, “7”, and enter the

seven remaining digits. For all ORION gas and water IEDS with serial numbers

equal to or greater than 80,000,000, enter all digits of the IED, which will be

from 8 to 10 digits.

There is no direct communication between the Intelligent End Device (IED) and

the HHTR-3.
