Inside the enclosure there are several 2-holed 
insertion points. These allows for either vertical or 
horizontal placement of legacy NX modules. Each 
insertion point has a larger hole and a smaller hole. 
1.  The black plastic PCB guides feature a groove to 
hold an expansion module. The end with the half-
moon protrusion fits into the larger hole. The 
smaller hole is for the screw. 
2.  Place the first black plastic PCB guide in the top 
insertion point, groove facing downward. The half-
moon protrusion will be in the large hole. It does 
not require force to insert. Insert one of the 
provided screws into the smaller hole (from inside 
the enclosure) to secure it in place. A screwdriver 
should reach through the groove that runs the 
length of the guide to tighten the screw. The 
second PCB guide should be positioned opposite 
the first (groove facing up) and placed in the lower 
insertion point, using the same procedures 
described above. Once mounted, screw it in 
securely. 
3.  The NX module should slide freely in the grooves 
of both guides. 
Installing Antennas 
A number of antennas may be provided depending on the model purchased. 
These include: 
•  Multi-antennas for legacy 433 63-bit, LoNa 80plus (NXG-4 only) and Z-Wave 
•  4G antennas for Wi-Fi/cellular module 
•  Wi-Fi antennas for Wi-Fi/cellular module
