Bidirectional Transparent Data TransmissionWith serial device server, traditional serial devices can be connected to local networks and the Internet Then users can transform traditional serial device into loT device.




- Multi-user Access
In TCP server mode, it suppports multiple TCP clients acess, so it can realize multi-user control of serial devices. - Multi-device Management
The USR-DR132/134 device connects to the central server for centralized management of serial devices.
- Virtual-COM Software
This feature can infinitely extend the serial cable,allowing communication to no longer be limited by distance. - Point-to-Point Communication
Using this method, it is possible to achieve data communication between two serial devices.


- Heartbeat Packet
Server can detect abnormal disconnection from the client using this feature(DR3X as an TCP client) - Registration Packet
The server can identify different clients by using registration packets.
- 3 Practical Designs, Easy Your Installation
- Ultra-small size like a lipstic, can be applied to various scenarios, especially the small box.
- Appearance patent number: 202130367085.8
