Mbox Modbus
RS485 ↔ 4GConnects air compressors, flow meters, power meters and other devices over RS485 via Modbus RTU, collecting running parameters and sending them to the cloud over 4G. Works with general-purpose controllers from many brands.
One box,and a single machine is on the cloud
Mbox is a lightweight IoT terminal for individual air compressors. It mounts on a DIN rail and connects to the existing controller with two signal wires; running status, alarms and key parameters go to the cloud platform over 4G — no changes to the original control system, no impact on the customer's production. Install it and the machine is online.

Mbox CANbus
CAN ↔ 4GReads compressor controllers with a CAN bus directly over CAN (CANH / CANL), capturing native running data and sending it to the cloud over 4G. Parameters in the cloud match the controller panel, with a more complete data set than generic register maps.
OEMs: pre-installed on new units 
Service providers: retrofit on the installed base Where the small box goes to work
Mbox is built to get single machines online fast. It is most often used in these three scenarios — no changes to the original control system; install it and the machine is online.
Service providers: installed base to the cloud
Retrofit Mbox on air compressors already running at customer sites. Two signal wires into the existing controller bring the installed base online quickly, ready for remote monitoring and service management.
Short-term efficiency measurement
When a machine needs a periodic assessment of power, air output and energy efficiency, install Mbox temporarily to collect running data. Remove and reuse it once the measurement is done — no cabling, no rework.
OEMs: online from the factory
Pre-install Mbox on new units on the production line. Machines leave the factory connected, with cloud records already in place at delivery — a solid foundation for remote operations and after-sales service.
Backed by RIYI cloud systems
Device identification and records
A record is created the moment a machine connects: model, serial number and running parameters are archived automatically — one record per machine, traceable across its full lifecycle.
Status collection and alarms
Running status, start/stop events and faults reach the cloud in real time, and abnormal events are pushed to your phone the moment they occur.
Trend curves and history
Review historical curves of key parameters at any time; device data is retained and traceable throughout the service period.
Service coordination
Data feeds into the Service Management System and the OEM IoT platform, connecting remote operations with after-sales service.

Even a single machine deserves to be online
Mbox is usually deployed together with the Service Management System or the OEM IoT platform. Tell us the brand and model of the machines on site, and our engineers will confirm the connection method and recommend a deployment.
