The module adopts TI Cortex-M4 SoC which can provide improved performance and higher stability.
The server can identify different clients by using registration packets.
Server can detect abnormal disconnection from the client using this feature (K3 as an TCP client).
Users can dynamically modify the baud rate of the K3 by sending PUSR customized protocol over the network.
Transfer between Modbus RTU and Modbus TCP protocol. Support Modbus multihost polling.
Built-in hardware watchdog，7*24h stable operation without downtime.
-40℃ ~ +85℃
Fully Enclosed Metal Protective Shield Built-in Ethernet Isolation Transformer
With this feature, users can change logo, style, company information and so on to advertise their own brand and enhance their brand influence
