Note it is a simple converter device - so it doesn't convert Modbus-TCP to Modbus-serial. This meant I had to code a Modbus-TCP-RTU master - which has some problems as responses in Modbus-RTU do not contain a transaction ID. If I repeat the same function code to the same slave with the same register count, the responses could get mixed up - my solution was to never do this (interleave requests with different register counts & checking response length resolves this issue). (This is a limitation of the Modbus protocol - not this device). I currently have two communicating to two different Modbus networks using different serial comms parameters - both have been running for prolonged periods without issue. ## Features - Rate:10/100 Mbps, MDI/MDIX, auto switch between cross and direct connection - Protection:2KV electromagnetism isolation, shell insulation blocking - Network Protocol:IP, TCP, UDP, DHCP, DNS, HTTP, ARP, ICMP - BufferSend: 6K bytes, receive: 4K bytes - Can work in LAN, also can work in the Internet external network ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BC77L8K | | Best Sellers Rank | #170,159 in Computers ( See Top 100 in Computers ) #365 in Network Transceivers | | Brand | BGNing | | Color | Black | | Colour | Black | | Compatible Devices | PC | | Compatible devices | PC | | Connector Type | RJ45 | | Connector type | RJ45 | | Customer Reviews | 4.0 out of 5 stars 68 Reviews | | Finish | Matte | | Finish type | Matte | | Item Weight | 0.23 Kilograms | | Manufacturer | USR | | Mfr Part Number | Q14870 | | Model Number | USR-TCP232-304 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | Industrial automation, security and protection monitoring, power control, environmental monitoring, intelligent agriculture, building automation system | | Specific uses for product | Industrial automation, security and protection monitoring, power control, environmental monitoring, intelligent agriculture, building automation system Specific uses for product Industrial automation, security and protection monitoring, power control, environmental monitoring, intelligent agriculture, building automation system See more | | UPC | 686603101926 | | Unit Count | 1 Count | | Warranty Type | Limited | ## Product Details - **Compatible devices:** PC - **Specific uses for product:** Industrial automation, security and protection monitoring, power control, environmental monitoring, intelligent agriculture, building automation system - **Connector type:** RJ45 - **Brand:** BGNing - **Finish type:** Matte ## Images ![USR U.S.R. -TCP232-304 1 Port RS485 TCP/IP Ethernet Converter Transmission Transparent Data - Image 1](https://m.media-amazon.com/images/I/619v5umsDxL.jpg) ![USR U.S.R. -TCP232-304 1 Port RS485 TCP/IP Ethernet Converter Transmission Transparent Data - Image 2](https://m.media-amazon.com/images/I/61skRzALFUL.jpg) ![USR U.S.R. -TCP232-304 1 Port RS485 TCP/IP Ethernet Converter Transmission Transparent Data - Image 3](https://m.media-amazon.com/images/I/61imFJpMX5L.jpg) ![USR U.S.R. -TCP232-304 1 Port RS485 TCP/IP Ethernet Converter Transmission Transparent Data - Image 4](https://m.media-amazon.com/images/I/612-crCd7aL.jpg) ![USR U.S.R. -TCP232-304 1 Port RS485 TCP/IP Ethernet Converter Transmission Transparent Data - Image 5](https://m.media-amazon.com/images/I/61J-04FJihL.jpg) ## Questions & Answers **Q: What is the serial port, rj45, db9, usb? male or female?** A: RS485*1+RJ45*1 serial RS485 to Ethernet converter ## Customer Reviews ### ⭐⭐⭐⭐ No es RS-485 a TCP/IP *by H***W on 29 June 2023* En la publicación dice que es RS485 a TCP/IP y la verdad es que es TCP/ASCII ### ⭐⭐⭐⭐⭐ Does the job *by A***R on 19 November 2022* I use these to master Modbus-RS485 devices.
