ACUMESH OVERVIEW
The AcuMesh wireless RS485 network solution is
designed to connect energy meters and any devices by
communicating with RS485 wirelessly. AcuMesh is a cost-
effective solution that eliminates the need for installation
of communication wires. Saving premium time, labour, and
reducing the challenges of retrofit applications.
LONGER, RELIABLE
COMMUNICATION
The AcuMesh wireless system makes use of the Mesh
network structure which allows each transceiver to act
as extension points in the network allowing for larger
range of communication. Using this Mesh arrangement
for communication allows for point to multi-point
communication. This solution enables automatic self-
healing to optimize the communication pathway for a
more reliable communication.

INSTALLATION CHECKLIST
You’ll need to confirm these details before successfully
completeing the installation of your AcuMesh system:
AcuMesh wireless system requires a
minimum of two transceivers to form the
network.
The RS485 network master device can be a
PC, PLC, data acquisition server or gateway,
e.g. AcuLink 710 Data Acquisition Server.
The slave devices can be our Acuvim II
series power meters or any other meter or
sensor with RS485 port. If it is the Acuvim II
meter, the AXM-Mesh transceiver module
should be used, for other devices the
standalone transceiver should be used.

STANDALONE TRANSCEIVER
POWER
The transceiver can easily be powered by connected it to the USB port of a
computer.
The AcuMesh transceiver can also be powered using a standard power supply of
100-240Vac or from an auxiliary wall socket to be powered.
Note: When the transceiver is connected to a gateway, PLC or power meter
through the RS485 port then the transceiver must be powered using the
external power supply.
The AXM-MESH module is directly powered by the Acuvim II series meter that it
is connected to.
LEDs
There are two sets of LED lights on the transceiver that indicate the transceivers
behaviour. The RSSI LED’s indicate the signal strength of the incoming signal.
3 LEDs ON - Very Strong Signal
2 LEDs ON - Strong Signal
1 LED ON - Moderate Signal
0 LED ON - Weak Signal
The Power LED’s indicates the activity of the transceiver.
The yellow LED indicates the transceiver is transmitting data.
The green LED indicates the transceiver is receiving data, the red LED indicates
the transceiver is powered on or it is communicating (the red light is on when
powered, off briefly during RF transmission).
HARDWARE INSTALLATION
Two types of Transceivers and two antenna choices.

AXM-MESH MODULE
ATTACHING TO A METER - ACUVIM II CONFIGURATION:
With the AXM-Mesh module attached to the meter, the meter should be
configured with the following settings to communicate:
Protocol 2: Mesh
NOTE: By changing the ‘Protocol 2’ setting to Mesh in the meter this will
automatically change the Baud rate 2 setting in the meter to 9600 and Parity 2
to None1
If the meter does not have Mesh option in Protocol 2, please set Baud rate 2 and
Parity 2 to 9600 and None1 respectively.
CONFIGURATION WITH OTHER DEVICES:
For other meters or devices that communicate through a RS485 port, the devices
must have the following settings to communicate with the transceiver:
Baud rate: 9600
Parity: None1 (Or Parity None, stop bit 1)
NOTES:
The Acuvim II meters and any other RS485 connected devices in the network
should be assigned with a unique Modbus address from 1-247.
The standalone transceiver can only be connected either via USB or via RS485 at
any time.

ADVANCED USER SETTINGS
Two types of Transceivers and two antenna choices.
CONGRATULATIONS!
By default, all the transceivers are configured in the same network. The
transceivers will be configured with the default network ID of 7FFF.
For advanced configurations such as configuring transceivers to work in a
different network, our “AcuMesh” software needs to be used.
NOTES:
A transceiver must be connected to a PC to perform any network configuration.
1. OPEN SOFTWARE:
Open the “AcuMesh” software. The following screen will appear.
The AcuMesh RS485 wireless network set up is complete. You are now able to
communicate wirelessly with all RS45 devices in the network. The AcuMesh
wireless RS485 network is pre-configured to work out of box. No software
configuration is required.
CAUTION:
Proceed with caution to advance user setting below, you will not need to use the
AcuMesh software to have the AcuMesh Wireless RS485 network working, only
use the software if you have knowledge of wireless network properties.

NOTE: If you change the Network ID setting of a remote module, it will lose
connection and will be lost immediately. In such case, the network setting in
the local transceiver needs to be modified with this Network ID so that the local
and remote modules can communicate.
To configure a remote module from default settings:
•Modify the network ID in the remote transceiver
•Modify the network ID in the local transceiver after connection between the
remote transceiver has been lost in the preceding step.Industrial and Factory
