BLE Bolt Adapter
Ble bolt adapter is a bridge product that converts industrial fieldbus can / RS485 / RS232 to Bluetooth wireless network.
As a cable replacement scheme, it can directly forward bus data to Bluetooth wireless network, and vice versa.
Any ble wireless device can be connected to the bus through a bolt adapter to interact with the devices in the bus.
In some occasions where it is inconvenient to approach the machine for direct operation, such as limited space, the cabinet door cannot be opened, or there are safety hazards, the equipment operator can access and control the machine from a long distance through the bolt adapter, which effectively avoids such problems.
The bolt adapter has a strong housing and unique shape.
By creating a 50mm through hole, it can be installed on any plane.
Combined with the basic protection installation kit, it can adapt to various harsh environments in factory automation.
The bolt adapter provides three data conversion modes when using CAN bus communication: transparent conversion, transparent band mark conversion and Modbus protocol conversion (supporting Modbus RTU protocol).
When using RS485 / RS232 bus communication, it directly transmits transparently.
Users can configure various parameters of the bolt adapter through Bluetooth.
