M2 Gateway and Wireless Remotes
The following quick connect diagram provides an overview of the M2 Wireless components
and how they are connected.
Before you begin….
Survey the location site and determine the best location for the antenna and remote units. For
optimal performance, the remote units should be placed in clear line of site, or unobstructed
view to the antenna. To improve line-of-site between remote and Gateway, use an appropriate
length of conduit to elevate the remote above the sensor.

Installing the M2 Wireless Gateway and Antenna
Mounting the Gateway
Mount the M2 Gateway on a DIN rail inside the
panel enclosure.
The M2 Gateway can be mounted vertically or
horizontally on a standard DIN rail. Two clamp-
type feet along the bottom of the Gateway attach
to the DIN rail.
NOTE: Rail stops are recommended to
prevent sliding.
Power
Power up the Gateway by attaching a power cable to the GND/BAT terminals and connecting
to a battery or power supply. Voltage must be between 8-32 volts DC.
Antenna Mounting
1. Mount the antenna bracket to the top of the panel, or
other structure, no more than 12 feet away from the
Gateway.
2. Attach the antenna coax cable to the Primary
Antenna connection on the Gateway. Feed cable
down and outside of the panel through a free
conduit hole. It is recommended that the coax cable
be run separately from other cabling and kept away
from noise sources such as the “G-Lead, cell
modem cabling, antenna, etc.
3. Attach the coax cable to the antenna through the mounting bracket, locking the antenna
into place.

GATEWAY RF Antenna Connection
Attach grounding plane in a horizontal position to a solid metal surface as shown.
Base of antenna should be 3‟6” to 5‟6” above ground.
Antenna should have clear line of sight to remotes for optimal performance.

PC Cabling and Software
A laptop is required to communicate MODBUS commands to the M2 Gateway. A USB-COMi
port should be configured for connecting to the Gateway, and MODBUS program should be
installed in order to activate the M2 Gateway and Wireless Remotes.
USB-COMi Setup
1. Open the USB-COMi USB to EIA-485 converter. Orient the converter and locate the
jumper block.
2. Remove all jumpers and then reinstall a jumper at positions 1-2, 5-6, 7-8, 11-12, 15-16,
and 19-20. Positions 3-4, 9-10, 13-14, and 17-18 do not have a jumper. Place excess
jumpers onto one pin of positions 3-4 and 9-10 so they hang off to one side for storage.
This configures the unit as terminated and transmit data echo suppression mode.
3. Reassemble the USB-COMi.
4. Locate the USB cable supplied with the USB-COMi. Connect the small end of the USB
cable into the USB-COMi and install the large end of the USB cable into the computer.
Do not connect USB-COMi into a USB Gateway or erratic behavior can result.
5. When Windows notifies you that “Found New hardware”, insert the driver CD supplied
with the USB-COMi into the computer. If the driver install does not start automatically,
select “Search for the best driver for my device” on the computer and then click “Next”.
Click on “Specify a location” and select your CD-ROM. Driver should now install on
computer.
6. “Found New Hardware” will appear again and this time it will install a USB serial port.
7. Right click on “My Computer”, click on “Proprieties”, click on the “Hardware” tab, and
then click on “Device Manager”.
8. Click on “Ports (COM & LPT)”. You should now see an entry for USB Serial Port
(COMX) where X represents the port number.
