CM520-8VX / 8AX
8A positioning and 8V non-positioning variants; Ethernet layout and vehicle power require clarification.
Specifications & documents →
CAIMOREVehicle connectivity.
Cellular routers for onboard IP equipment and serial devices. Select the hardware configuration, then validate it in your vehicle system.
Product lineup
Three documented series. Exact radio and interface configurations remain model-specific.
Connect onboard equipment to your operating system.
Choose the cellular configuration
Compare documented 4G / 5G variants and cellular module options against destination-country networks. SIM count and failover behavior must be fixed per model.
CM520-6XX / 8A / 8V →Bring IP and serial equipment together
CM520-61 and CM520-64 list one Gigabit WAN, four Gigabit LAN ports and RS232. Match cameras, terminals and controllers to the exact interface layout.
CM520-61 / CM520-64 →Select positioning where needed
The 8A selection guide lists GPS / BeiDou; 8V does not list positioning. Validate antennas, mounting and vehicle power protection during OEM evaluation.

Applications & integration
Illustrative architecture. Sensors may require a PLC or acquisition module. Interface and cellular options depend on the selected model. VPN protocol, authentication and access policy require firmware-specific configuration; SCADA compatibility and control logic belong to the customer system.
Review CM520-8A / 8V specifications →Onboard surveillance
Map camera bandwidth and Ethernet port needs. PoE supply and recorder integration must be specified separately.
Fleet telematics
Match serial signals, GNSS option and customer-server protocol. Validate antennas and recovery behavior in the intended vehicle.
Vehicle OEM integration
Review mounting, harness, ignition behavior, transient protection and certificates. Sample approval should cover the actual hardware and firmware.
