Introduction
1.1 Product Overview
Automatic Meter Reading (AMR), also called remote meter reading system, is a new
meter reading way to finish meter reading without people on site. Via
communication technology, it can be automatically transferred to the data in
Watt-hour meter the accounting and management center for efficient handling.
Also, it can be provided real-time measurement information to help the users to
optimize their energy supply solutions.
Aiming at AMR application, M2Micro launches its MMR6000 AMR system, which
supports ad hoc network and data collection for various types of meters. It is mainly
made up of MRU6000 terminal units and MCC6000 control units and OMS meter
management system.
The main function of MRU6000 is to collect the electric data through RS485 bus,
and upload it to the control unit with the wireless communication module.
1.2 Features

Modular design, existing meters can be upgraded by attaching wireless AMR
modules.

Support hybrid meter reading, can collect data of water meter, gas meter, etc.
MRU6000 Installation Guide

Based on M2Micro developed chips, MAC and PHY layer can work together
perfectly.

Support 433.92MHz frequency band, with good transportation distance and
penetration.

Support Ad-hoc network, can be deployed to complicate environment.

2.5.1
Product introduction
MRU6000-WM01 could mount more than one meters, it can be used in
concentrated meter box. MRU6000-WM01 is powered by DC Supply. It can collect
measurement data of meters through RS-485 bus and then send out collected data
by wireless connection.
 Tips:
1. Considering the power supply issue, only multiple electric meters are allowed
to be connected to the same terminal unit. Neither connection of multiple
water meters/gas meters with a same terminal unit, nor connection of hybrid
meters with a same terminal unit , can be supported.
2. MRU6000-WM01 can be connected to more than one electric meter, but all
