USR-DR132/134 | “Lipstick” Size Serial Server Device

The USR-DR132/134 is an ultra-small size serial server device with one serial port. It can realize transparent transmission between RS485/RS232 and Ethernet ports. It supports timeout restart, DHCP, DNS and other advanced features such as heartbeat packet, registration packet etc. It can make it easy for data transmitting of the field serial device.

Key Features

● Lipstick” Size: Save Your Space

● Rich Protocols: TCP/UDP/HTTP/DHCP/DNS

● Modbus Gateway: Modbus TCP/RTU conversion, Modbus RTU to JSON

● Easy Config: AT command, built-in webpage, config utility

Serial to Ethernet,
Bidirectional Transparent Data Tata Transmission

With 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.

Ingenious Design, Beyond Ordinary

In a space no larger than a finger, multiple industrial-grade components are integrated to ensure the stable operation of the product.

One More Thing, Modbus Gateway

Connect to PLC, SCADA system or user’s private server to achieve local or remote motoring.

Multiple User Scenarios

• ● 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.

• 
  

Multiple User Scenarios

• ● 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.

• 
  

Additional Features

• ● 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.

• 
  

Ultra-small Size

• ● 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

Easy connection

Push-type, pluggable wire connector, easy wiring, no need for additional tools such as screwdrivers.

• ● Push wire connector

• ● Pluggable wire connector

High Reliablity Design

• ● Watchdog Protection Hardware & software dual watchdog to ensure stable operation.

• ● EMC Protection: Level 2.

• ● Auto Re-Connection Automatically monitor connection status, reconnect once disconnet.

• ● Wide Operating Temp -40℃ ~ 85℃, industrial grade design, stable operation in harsh environments.

Applications

The card reader or video input device is connected to the USR-DR13X via a serial port. The serial port server transmits the serial device information over the local area network to the central control system. After information comparison, the central control system determines whether to allow personnel in and out of the access control system.
