POWER CONNECTION AND MODBUS CONNECTION
The W-Modbus units have 24 VAC/VDC power in/out connection and con-
nection for Modbus communication.
INSTALLATION
1. Conrm that the W-Modbus unit has no visible damage
2. Install the W-Modbus unit close to the Client/Server it should be con-
nected to
3. The W-Modbus enclosure is wall mounted and ts onto a junction
box. Start with mounting the back piece of the enclosure.
4. Connect the power supply and Modbus Client/Server to the W-Mod-
bus unit, as shown to the right. Use the rear and/or top knockouts for
cable entry. All W-Modbus units are factory set for Node operation
without the need for additional conguration when connected to a
Modbus Server.
5. Fit the front piece to the back piece
6. Check that the W-Modbus unit and its wiring are securely mounted
(ifthe unit is powered this will be indicated by the LEDs)
W-Modbus is an end device with internal termination resistor.
APPLICATION AREA
The W-Modbus product transmits Modbus RTUsignals wirelessly. It is
designed to be used indoors as a Modbus RTU cable replacement.

SYSTEM OVERVIEW
A W-Modbus network consists of a single W-Modbus Gateway connected
to the Modbus Client using a Modbus RTU cable and up to 100 W-Modbus
Nodes, each of them connected to one Modbus Server over a Modbus
RTU cable.

The W-Modbus network is built on LumenRadio’s MiraMesh, a self-forming
and self-healing wireless mesh technology. For more information about

All uncommissioned W-Modbus Nodes will, at power up, start scan-
ning for a W-Modbus Gateway. The LEDs will turn blue color and
ow from top to bottom during this process.
To initiate the W-Modbus Gateway node scan, position the 3 pole
switch in the middle position on the Gateway. During the Gateway
scan process the 3 LEDs will ow from top to bottom in green color.
Wait for all W-Modbus Nodes to nd and connect to the Gateway,
the LEDs on the Nodes will start to ash in green color. This process
can take up to 5 minutes.
When connected, set the switch on the W-Modbus Gateway to the
bottom position. This will restart the W-Modbus network in secure
mode. This is indicated by the top LED, yellow for W-Modbus Ga-
teways and green for W-Modbus Nodes. In this mode the status of
wireless signal strength and Modbus RTU cable connection status
will be indicated by the LEDs as shown under System status.

Set the baud rate, parity and stop bit settings on the W-Modbus Gateway to
match the settings of the Modbus Client.
All W-Modbus Nodes are by default congured to receive their baud rate,
parity, and stop bit from the W-Modbus Gateway in the system. It is possible
to override the individual W-Modbus Node setup, effectively mixing settings
within the network.
After setting Baud Rate, Parity and Stop Bit, each
W-Modbus Node will scan for the connected
Servers Modbus address
(1-255) in sequence, it may
take up to 2 minutes before
the address is found.

SYSTEM STATUS
Does the unit have power? Press the push button, if the LEDs are
not switched on, check the power connection.
Can the Modbus Client handle the timeout requirements?
Is the unit connected to the network?
Check the Wireless Network status LED. A Node with a owing blue
light is not connected to the network. Reference the commission
section to ensure the unit ashes green before switching the Ga-
teway into secure mode. If the owing blue light persits the range
of the unit might be too far away from the network. Try installing an
extra W-Modbus unit in between.
Is the network within the limits of the maximum (100) units allowed?
If the Wireless Network Status indicates bad wireless network (red
LED) make sure the distance between W-Modbus units are within
the requirements or add an extra W-Modbus unit as a repeater to
get better wireless coverage.
If the Modbus RTU Cable Communication indicates no communi-
cation (red LED) check if the Modbus RTU cable is correctly instal-
led and make sure the Baud rate, Stop bit and Parity settings are
correct.
Have all the Nodes joined during commissioning (all LEDs ashes
green) but not all nodes entered the secure network when the Ga-
teway is set to secure network (yellow LED). Make sure only one unit
is set to Gateway mode during commissioning. It is only possible to
install one network at a time.
