Wired M-Bus 

The M2M Control CX320 has an onboard wired M-Bus interface compliant with EN 13757-2/3 and 
offers a comprehensive API for communicating with up to 20 slave devices on the bus. 
 
The M-Bus interface is short-circuiting protected and supports full master-mode functionality. The 
M2M Control CX320 device needs to be supplied with an external supply for the M-Bus interface to 
be operational.

Wireless M-Bus (optional) 

The M2M Control CX320 supports an optional onboard wireless M-Bus interface compliant with EN 
13757-4/7 and offers a comprehensive API for collecting data from wireless M-Bus slaves. 
 
The Wireless M-Bus interface is designed for OMS EU/CE applications, but other variants are also 
available on request. 
 
The module has support for modes S1, S2, T1, T2, and R2 as  well as common reception of mode T 
and mode C1 in the form of mode T1+C1 and T2+C1.
