G400 Cellular Installation Guide

The VergeSense G400 Gateway is a device that communicates with the local network of VergeSense sensors to aggregate local occupancy data. The data is transmitted to a cloud server by tapping into an internal IT network or via a cellular backhaul, or routed to an internal network. 

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.

Assembly Guide


Step Description Image
1 Remove hardware from cellular kit and remove components from packaging. 
2 Install USB adapter (5) onto cellular dongle (7)

Insert both antenna adapter cables (6) into cellular dongle (7) as shown. 

Note: Special consideration is to be taken keeping sure cables are parallel and not tangled. 

Notice dongle orientation. The USB adapter is located on the left side. 

1 Remove G400 device (2) from packaging and place it next to the cellular dongle (7) with the USB-C port facing up.

Insert USB-C adapter (5) into the USB-C port on the G400 device (2).

Note: The G400 device ethernet port should be accessible. The antenna adapter cables (6) should lay over the G400 device.


With the cellular dongle (7) inserted, place the G400 device (2) into the slot in the cellular housing (1). It will click into place. 

Place the cellular dongle (7) and USB-C adapter (5) into the slot. 

Caution: The antenna adapter cables (6) should should lay over the G400 device (2).


Attach the cellular housing bottom housing (2) to the top housing (1).

Insert the two tabs on the bottom housing (1) into the two inserts on the top housing (1).

Press the two housing parts together clicking them into place. 

Note: the ethernet port on the G400 device (4) should be accessible via the access hatch on the cellular housing. 


Attach the 2 antennae by hand tightening. 

Caution: Do not use tools as they may damage the unit. 

6 Unbox the power unit from packaging
7 Insert one end of the ethernet cable into the “PoE” port on the PoE adapter. 

8 Insert the other end into the ethernet port on the G400 device (4)
Insert the PoE adapter into the AC power outlet to power on the device.

Step Instructions Photo
1 Locate the mounting location keeping the best placement guidelines in consideration   

Use the mounting the cellular bottom housing (2) as a template to mark the screw locations. 

Make pilot holes if required

3 Pass the ethernet cable through the access hole on the cellular bottom housing (2)  
4 Holding the cellular bottom housing (2) in place, drill the 4 mounting screws through the screw holes  
5 Insert one end of the ethernet cable into the “PoE” port on the PoE adapter. 

6 Insert the other end into the ethernet port on the G400 device (4)  
Insert the PoE adapter into the AC power outlet to power on the device. 



  • Inserting the USB-C adapter incorrectly into G400 leading to improper installation of device into housing
  • LED light on G400 and cellular dongle are not easily visible. May lead to longer support events in the cases a ladder may need to be dispatched. This will be the case for gateways installed in ceiling
    • LED viewing is accessible as standard design for comparable devices i.e. Rigado gateway, wireless access point, other VergeSense sensors 
  • Device ID is not included on the cellular housing. This requires disassembly which interrupts service and requires technician dispatch in cases where user cannot support 
  • Ethernet cable and access location causes tension on the ethernet port. May lead to hw issues
  • Wall mount requires ethernet cable to be passed through first. This prevents user from accessing the device without disassembling and unplugging device
    • For reference: Rigado device mountain plate can be installed first followed by device attaching to the mounting plate. No disconnecting is required
    • Need updated photo*

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.


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 as shown in the image below. (Need IMAGE)
  • 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.
  • Place in a location with strong cellular connectivity

Confirming Connectivity

Power the gateway by inserting the ethernet cable. The sensor will automatically power on.

The VergeSense wired gateway contains an LED next to the soft reset button on the side of the sensor. The LED is intended to provide an indication of the sensor's status during initialization. During normal operation, the LED will be turned off and the sensor's status should be visible in the VergeSense dashboards. During initialization, the LED should exhibit the following behavior:

Commissioning the Gateway

  • Before the Gateway is permanently installed, look at the side and record the unit Serial Number in the Installer Tool.
  • Once connected, confirm timestamp is recent
  • Select Publish
  • Restart the device if it is having issues connecting

The green gateway icon indicates a successful installation. The wireless network is now set up and VergeSense sensors can start communicating to the gateway.
