Product Name:Ethernet Modules | Ethernet to Serial Modules
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
