900MHz WAM Connect
Overview
Customer Provided Equipment and Materials
The user must provide an active local network for this gateway. The user’s Windows
7 or higher computer must have the WAM Link connected via a USB port and WAM
Design installed on their PC.
At locations where there is a secure network and foreign equipment is not allowed,
it may be necessary to provide a separate router and network switch. This decision
depends on the number of connections needed, which will allow the installer to set
up an isolated network for the gateway network connections.
Placement Recommendations and Building Material Attenuation Losses
• 275 feet line of sight (LOS) is the maximum range that can be
expected. Actual range will vary based on the environment.
• All materials that block the path of transmission between a sensor
and gateway contribute to signal loss. See chart to the right for
some common materials and expected signal loss.
• The gateway should be mounted as far away from metal
obstacles as possible to avoid RF reections or blockages.
• Mounting to drywall between studs, ceiling tiles, brick, glass or
concrete is very common. Mounting to ceiling T-Bar is common
but will a󰀨ect distance due to the metal in the T-Bar and the
horizontal orientation.
BAPI recommends conducting a bench test before permanently
mounting the gateway to assure strong communication between the
gateway and sensors. Once bench testing is complete, temporarily
place the gateway and sensors in their desired locations.
Material Attenuation Loss
Brick 3.5" (89 mm) 3.5 dB
Brick 7" (178 mm) 5 dB
Brick 10.5" (276 mm) 7 dB
Concrete 4" (102 mm) 12 dB

Dongle
Multiple communication options including BACnet IP and MQTT.
 Each gateway supports up to 50 sensors that can be congured remotely via the gateway.
 The system uses “smart logic” to nd and secure a clean frequency channel rather than “frequency hopping”.
 Easily congure wireless sensors to be presented to BACnet network via a at mode for single gateway device with
sensors as associated objects.
The BAPI wireless gateway is a device that allows for the receiving of up to 50 BAPI
900MHz wireless sensing devices and outputs that received information in one of two
formats: BACnet IP for your typical Building Automation system and MQTT for BAPI WAM
(Wireless Asset Monitoring).
The BAPI gateway can be powered from the supplied plug-in power supply or Power
over Ethernet (PoE) if your network supports that feature. The wireless network setup
application (WAM Design) lets you assign your wireless devices to the appropriate gateway
while also allowing you to note sensor names, location, settings, etc.
You will need to have a BAPI Wireless USB Dongle (WAM Link) to commission the system.
This dongle acts as a default radio module which you will need to discover the wireless
sensors that are in the factory default mode. With this tool and the application on your
computer you will be able to “hand o󰀨” the sensors to the appropriate gateway.

900MHz WAM Connect
Setup
Note: BAPI’s 900 MHz System has many available features and options, so patience is key while conguring the gateway
and sensors. Please read all the steps prior to starting which will help with the process. If you have questions after reading
all the steps, call BAPI for assistance and one of our wireless tech will walk you through this process.
1. Choose a convenient location for a “bench setup” of your system prior to installing it in the nal
location.
Choose a “bench setup” location with the sensors, gateway and computer within easy reach. Remove the gateway
from the box and attach the antenna. Connect the supplied ethernet cable to the gateway and the network. Connect the
supplied power cord to the gateway and then into the wall outlet if you are not able to use PoE.
2. Download and open the BAPI WAM Design Application
Download the WAM Design from this address (Contact BAPI for link
address.) Plug WAM Link into an available USB port on your computer.
Open the Design Application. Make sure your WAM Link Dongle
displays in the pull down box of the initial screen (Fig 3). If it does not,
click the red “retry” arrows to the right of the box. The WAM Link dongle should
automatically identify itself to WAM Design software.
3. Run the WAM Design Application
Click start. A dialog box will show up asking for a password. If you wish, assign
a password to the gateway. If not, press “Yes” to continue. This will open the
Conguration Screen shown in Fig 4. The left column lists the available gateways
that are on the same network as your computer. Click on the gateway that you
plan to congure and “hand o󰀨” the sensors to.
The center column tabs show the selectable options for the gateway.
• Network: This is the network setting for your LAN should you decide to change any of them.
• Settings: This is where you can make changes to the gateway such as its name.
• WAM: This is where you select the end destination path for all MQTT settings.
• Sensors: This is where you “hand
o󰀨” sensors to the gateway.
• FDR: This is the Foreign Device
Registry BACnet tool.
• Backup: This is where you can
back up your settings or recover a
stored backup. See the “Backup and
Restore Gateway” section for more
information.
There are also some additional options
on the Settings dropdown in the upper
left menu:
Sensor Cloud On/Off:
“On” – saves the names of the sensor
and gateway to a secure BAPI cloud
location for retrieval at a later time.
“O󰀨” – Sensor and gateway names are
not saved to the cloud.

appear (Fig. 9). Enter the sensor
name and BACnet ID if using
BACnet. See Step 8 “Conguring the
Sensors” for more info.
When prompted, press the ping/train
button on the sensor. This “hands
o󰀨” the sensor to the gateway from
the USB dongle. The communication
between the sensor and gateway
will then appear in the dialog box at
the bottom of this window. This is a
good way to conrm your sensor has
accepted the “hando󰀨”.
If after a “hando󰀨” process the sensor
still appears in the right sensor
column and turns green at the press
of the ping/train button, the hando󰀨
was unsuccessful. Please repeat the
process.
(Note: The sensor may appear in
both columns. If this happens, right
click on the sensor in the center
column and select delete, and then
repeat the hand o󰀨 process.)
The Conguration Screen in
Fig 8 shows a successful hando󰀨 of
sensors to the gateway. Note that all
the sensors have been removed from
the right column and are now in the
center column. These sensors are now “handed o󰀨” or assigned to the gateway that is highlighed in the left column.
Note: When all the sensors are “handed o󰀨” to the gateway, you must click the “Send” button to upload all the
settings changes to the gateway. After clicking the “Send” button, a dialog box will appear asking if you want to
reboot the gateway. This is not required.
8. Conguring the Sensors
The sensor can be congured when it is rst assigned to the gateway but if changes need to be made, you can get to
these settings by right clicking on a sensor in the center column of the Conguration Screen which opens the Edit Link
Sensor window (Fig 9).
Note: To properly set up a sensor, the sensor must be
handed off and associated with the gateway.
The “Sensor Info” section at the top of the window shows the
following:
• Serial Number: The serial number of the radio on the sensor.
• Sensor Type: The type of sensor.
The “Naming Tab” (Fig 9) lets you edit the following:
• Name: The name of the sensor.
• Location: The location of the sensor.
• BACnet ID: Assigns the BACnet Object Instance ID.

By default the gateway assigns the BACnet Object Instance ID for the rst sensor starting at 1000. It will go up by 1000
for each additional sensor added, so the BACnet Object Instance ID for the second sensor will be 2000. If a sensor is
removed, the next sensor added to the system will have the lowest available default number. This is important to know
when replacing a sensor.
Notice in Fig. 13 on page 10 that each sensor has multiple objects related to it. For example, room sensor 9544 has a
BACnet Object Instance ID of 1000, so all the objects associated with it (temp, humidity, setpoint, etc.) will begin with
1000. As shown in the chart below, the object instance for the temperature value is always “0” so the temperature value
for the rst sensor is 1000. The object instance for the Humidity value is always “1”, so the humidity value for the rst
sensor is 1001. For the second sensor (749E), the temperature and humidity values are 2000 and 2001 respectively. Note
that the object instance is skipped if that value is not available from that sensor, so there is no 1003 or 2003 for the rst
two sensors since neither of them has light level sensing.
You can assign your own BACnet Object Instance IDs for the sensors rather than taking the defaults assigned by the
gateway. However the IDs must be at least 10 numerals apart from each other. If you do not assigned them at least 10
apart, the system will not recognise them. For example, if you assign BACnet IDs for three sensors as of 6000, 6001 and
6002, the second two sensors will not save on the system because their IDs are already being used as the humidity and
setpoint or Barometric pressure values for the rst sensor. Instead you must assign numbers that are at least 10 apart
from each other, such as 6000, 7000 and 8000 or 6000, 6010 and 6020.
BACnet Object Instance Chart
Object Type .....Object Instance ..........Object Description
Analog Input ................. 0.......................Temperature in °C or °F
Analog Input ................. 1.......................Relative humidity in %RH
Analog Input ................. 2.......................Setpoint for room sensors / Barometric pressure in kPa for non-room sensors
Analog Input ................. 3.......................Light level in LUX
Analog Input ................. 4.......................Battery voltage level in volts
Analog Input ................. 5.......................Received wireless signal strength in dBm
Binary Input .................. 6.......................Occupancy override status
Analog Ouput................ 9.......................Heartbeat check (described on page 11)
Note: the object instance is skipped if that variable is available from the sensor, so there would be no “2” value for a
sensor without humidity measurement.
The “Radio Tab” (Fig 10) on Edit Link Sensor Window lets you edit
the following:
• Network: The network address of the sensor assigned by the
gateway
• AES Key: This is the AES encryption used between the gateway
and device assigned by the gateway
• Channel: This is the radio channel the sensor is using. Assigned
by the gateway
• Power level: dBm level of the radio. 0 dBm will yield good battery
life. Default = 0 dBm. Adjustment range = -30 to +5 dBm.
• Interval: Is the time between transmissions in seconds.
300 sec = 5 min. Default = 5 min. Adjustment range = 30 sec to 15
min.
• Battery: The voltage at which the battery is going to stop
transmissions due to an expiring battery.
Note: Once the battery drops below 3 volts, the battery is very
close to end of life and should be replaced.
