2 INTRODUCTION
2.1 ProtoAir Gateway
NOTE: The BMS Gateway (BMS-GW) is a co-branded hardware and software solution
manufactured by Sierra Monitor Corporation (SMC). The Synaspe Wireless p/n for this
product is BMS-GW. However, within this document, the BMS-GW will be referred to as the
ProtoAir, which is the product name provided by SMC.
The ProtoAir wireless gateway is an external, high performance building automation multi-protocol
gateway that is preconfigured to auto-discover the SimplySNAP site controller SS420/450 (hereafter simply
called “device”) connected to the ProtoAir and automatically configures them for BACnet/IP, BACnet
MS/TP, Modbus TCP/IP and Modbus RTU.
It is not necessary to download any configuration files to support the required applications. The ProtoAir is
pre-loaded with tested profiles/configurations for the supported devices.
FPA-W44 Connectivity Diagram:
The ProtoAir can connect with Sierra Monitor’s SMC Cloud. The SMC Cloud allows technicians, the OEM's
support team and Sierra Monitor's support team to remotely connect to the ProtoAir. The SMC Cloud
provides the following capabilities for any registered devices in the field:
•Remotely monitor and control devices.
•Collect device data and view it on the SMC Cloud Dashboard and the SMC Smart Phone App.
•Create user defined device notifications (alarm, trouble and warning) via SMS and/or Email.
•Generate diagnostic captures (as needed for troubleshooting) without going to the site.
For more information about the SMC Cloud, refer to the SMC Cloud Start-up Guide.

3 PROTOAIR SETUP
3.1 Record Identification Data
Each ProtoAir has a unique part number located on the side or the back of the unit. This number should be
recorded, as it may be required for technical support. The numbers are as follows:
Model
Part Number
ProtoAir
FPA-W44-1620
Figure 1: ProtoAir Part Numbers
•FPA-W44 units have the following 3 ports: RS-485 + Ethernet + RS-485
3.2 Configuring Device Communications
•The device needs to be on the same IP subnet as the ProtoAir and the configuration PC.
•Record the following device information:
oIP Address
oIP Port
oUsername
oPassword
NOTE: This information is required for Section 7.
3.3 Attaching the Antenna
Wi-Fi Antenna:
Screw in the Wi-Fi antenna to the front of the unit as shown in Figure 41.
NOTE: Using an external antenna is also an option. An external antenna can be plugged into the
SMA connector. The best antenna for the job depends on the range, topography and
obstacles between the two radios.

4 INTERFACE THE PROTOAIR TO DEVICES
4.1 Wiring Field Port to RS-485 Serial Network
•Connect the RS-485 network wires to the 3-pin RS-485 connector on the R2 port. (Figure 2)
oUse standard grounding principles for RS-485 GND
•See Section 6 for information on connecting to an Ethernet network.
