The VergeSense G400 Gateway is a device that communicates with the local network of VergeSense sensors to aggregate local occupancy data.
In a typical office environment, we suggest using one gateway per 50 devices. The sensors form a wireless mesh network with the gateway being the transfer point from the mesh network to the cloud. The maximum distance from the gateway to the nearest sensor in the wireless mesh should not exceed 40 feet.
Ideally, several sensors in the wireless mesh will be in close proximity to the gateway to ensure a reliable path back to the gateway across the wireless sensor mesh.
Gateway Location
Using the Installer Tool, find the gateway location on the map.
Power Requirements
Power can be delivered through power over ethernet or by plugging the provided AC/DC Power Adapter into a wall outlet and plug ethernet cable into ‘OUT’ and the G400.
Confirming Connectivity
Power the gateway by inserting the ethernet cable or by plugging the provided AC/DC Power Adapter into a wall outlet and plug ethernet cable into ‘OUT’ and the G400.. The gateway will automatically power on.
The VergeSense wired gateway contains an LED next to the soft reset button on the side of the device. The LED is intended to provide an indication of the gateway's status during initialization. During normal operation, the LED will be turned off and the gateway's status should be visible in the VergeSense dashboards. During initialization, the LED should exhibit the following behavior:
| Color | Pattern | State |
| Cycle through red, green and blue | Approximately 0.5 seconds on each colour | Initial power and system initialization (approximately 30 seconds) |
| Green | Solid on | System Initialised |
| Green | Flashing - approximately 0.5 seconds on/off cadence | Searching for Network address |
| Blue | Flashing - approximately 0.5 seconds on/off cadence | Connecting to VergeSense Cloud |
| Off | Off | Normal operation |
Gateway Network Provisioning (If Needed)
The gateways are shipped without network credentials pre-configured onto the device. The provisioning is completed on site by using the included USB-C drive. The drive contains the file required for provisioning.
Here are the steps for provisioning the gateways to connect to the wireless network.
This process takes about 5 minutes:
- The USB-C drives that are shipped with the G400 gateways are pre-loaded with the Wireless configuration file
- Remove the USB-C drive from packaging
- Power on the G400 gateway
-
- Power the G400 using either Power over Ethernet or the AC/DC Power Adapter plugged into a wall outlet.
-
- Installing the USB-C drive to the gateway:
- When the gateway has gone through initialization and LED is off - normal operation (it will take up to a minute for gateway to fully boot), insert the USB-C drive.
- Wait 10 seconds for LED to turn solid blue
- Wait about 30 seconds for LED to turn back off
- The LED should exhibit the following behavior:
| Color | Pattern | State |
| Blue | Solid on | Reading network configuration file |
| Green | Solid on | System Initialised |
| Green | Flashing - approximately 0.5 seconds on/off cadence | Searching for Network |
| Off | Off | Normal operation |
- When the LED is off, remove the USB-C drive.
- Remove and reinsert the PoE cable to restart the gateway.
- The LED will start flashing green. The LED will turn off indicating that the gateway is connected.
Mounting
Recommended mounting height is above 8' (2.4m).
The gateway communicates to the sensors in the wireless mesh using a 2.4GHz radio signal. The radio signal can be blocked by humans, panels of glass, metal framing, computer monitors and any combination of metal, glass or water. For optimum radio performance the gateway should be in line of sight with several sensors, and above human head height.
If a suspended ceiling is employed at the place of installation, for aesthetic reasons it may be viable to install the gateway above the suspended ceiling tiles. As long as the ceiling tiles are not constructed out of metal, glass or contain liquids.
- Wall & Ceiling Mount: The gateway kit comes with a mounting bracket that allows for the gateway to be mounted onto a wall or ceiling
- Special consideration should be given to any metal near the mounting area. Mount away from any metal surfaces such as metal ceiling tiles, shelves, cabinets, HVAC ducts, and other obstacles. For example, at sites with metal ceiling tiles, gateways should be mounted high on the wall instead of the metal ceiling.
- For optimal range, it is best to install a gateway facing towards the coverage area. Maintain a clear line of sight or minimize obstacles to desired coverage areas.

Commissioning the Gateway
Follow the below steps to commission the gateway in the VergeSense platform
- Before the Gateway is permanently installed, look at the side and record the unit Serial Number in the Installer Tool.
- Once connected, confirm the timestamp is recent
- Select Publish
The green gateway icon indicates a successful installation. The wireless network is now set up and VergeSense sensors can start communicating to the gateway.
Proceed to Installing a Wireless (L302) Sensor to continue the installation.
