With a footprint smaller than an Ethernet cable, it supports multiple network protocols and multi-user access, making it ideal for professional industrial and IoT applications. Note: This model does not support MQTT. ## Description Product description 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 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. 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. Review: Does Not Support MQTT - Listing falsely states it supports MQTT. A newer model does, but the one shipped does not and can’t be upgraded via firmware to support it. Support will send you a link to another site to purchase the updated model. Review: Works well, good instructions and software - Worked well, good instructions and the necessary software was easy to get and installed and worked correctly first time. It's tiny, just a bit wider than the Eth cable so doesn't take up much space. ## 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 Transmission ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D4M4HTDV | | Best Sellers Rank | #5 in Computer Networking Device Servers | | Brand | PUSR | | Compatible Devices | Desktop | | Customer Reviews | 3.6 out of 5 stars 8 Reviews | | Data Link Protocol | Ethernet | | Data Transfer Rate | 100 Megabits Per Second | | Hardware Interface | Ethernet | | Item Weight | 4.32 ounces | | Manufacturer | PUSR | | Mfr Part Number | DR132(RS232 to Ethernet) | | Model Number | DR132(RS232 to Ethernet) | | Unit Count | 1.0 Count | | Warranty Description | 2 years | ## Product Details - **Brand:** PUSR - **Compatible Devices:** Desktop - **Data Link Protocol:** Ethernet - **Data Transfer Rate:** 100 Megabits Per Second - **Hardware Interface:** Ethernet - **Item Weight:** 4.32 ounces - **Manufacturer:** PUSR ## Images ![Din Rail Tiny Size RS232 to Ethernet Converter Serial Device Server Modbus Gateway Modbus RTU to Modbus TCP Support Mqtt Edge Computing USR-DR132 - Image 1](https://m.media-amazon.com/images/I/31AM4VtsKtL.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐ Does Not Support MQTT *by A***. on June 18, 2025* Listing falsely states it supports MQTT. A newer model does, but the one shipped does not and can’t be upgraded via firmware to support it. Support will send you a link to another site to purchase the updated model. ### ⭐⭐⭐⭐⭐ Works well, good instructions and software *by R***E on August 26, 2025* Worked well, good instructions and the necessary software was easy to get and installed and worked correctly first time. It's tiny, just a bit wider than the Eth cable so doesn't take up much space. ### ⭐ NOT MODBUS Compliant! Does not support 125 register polling *by K***. on October 3, 2025* This gateway works as a modbus bridge both in IP master or RTU master modes. However it only supports modbus queries of 123 registers or less. Modbus standard is 125 registers. If you are doing a single request of less than that it will work but if you are polling large, sequential, register blocks this device will fail. I've emailed support with the issue with no answer.
