## Overview

The USR-TCP232-306 is a compact, cost-effective serial-to-Ethernet converter supporting RS232, RS485, and RS422 protocols. Featuring a 10/100Mbps RJ45 port, it enables bi-directional transparent data transmission with configurable baud rates up to 230.4 Kbps. Designed for professional environments, it supports multiple network modes (TCP/UDP/HTTPD), up to 16 client connections, and offers smart connection management with heartbeat and auto-restart functions. Configuration is streamlined via a built-in web interface and virtual COM port software, making it ideal for remote device control, data acquisition, and legacy machine networking.

## Description

USR-TCP232-306 is a multi serial port ethernet converter,which can realize bi-directional transparent transmission between RS232/RS485/RS422 and Ethernet. User can directly process data interaction through network and device to realize remote data acquisition, remote control and management. Features Auto-MDI/MDIX, RJ45 port with 10/100Mbps Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client Baud rate of serial port can be configured from 600 bps to 230.4 Kbps, supports check bit of none, odd, even, mark and spaceHeartbeat package mechanism to ensure connection is reliable, put an end to dead linkUser-defined registration package mechanism, check connection status and use as custom packet headerUnder TCP Server Mode, the connection number with client can be randomly set from 1 to 16, default number is 4. IP has been connected can be shown according to connectiong with calculating send / recceive dat. When connection number reaches a maximun, the new connection is kicked off the old one can be configured by user Parameters can be configured by built-in webpage, AT command, serial port procotol and network procotol. Setting procotol is avaliable to integrate into user¡¯s software. Supports TCP client short connection function, user-defined the disconnected time.Device restart if no data transmission or timeout. User-defined the restart time. If data buffer needs to clear configuration before TCP connection establishment Supports DHCP, automatically obtain an IP address and query IP address via serial setting protocol.The global unique MAC address, user-defined MAC addressDNS functionDNS server addres can be definedFirmware can be upgraded by networkProvide Virtual com software Restore factory setting through software or hardware Running across the gateway, switches or routers. Can work in LAN, also can work in the Internet

Review: Works as advertised, just a little slow (Updated). - TCP Server mode worked exactly as expected. I am able to send raw data via tcp sockets to the device, and it simply forwards it along out the serial port. A response/acknowledgement is forwarded right back through the opposite direction. Setup was quick and easy. The missing star is for latency. I am seeing up to a few whole seconds before my data is passed through to the serial endpoint. The response is sent back almost instantly, so I’m not entirely sure wherein lies the bottleneck. Not disappointed given the price of the unit. Update: After some more experimenting, I found that the latency I was experiencing was the unit trying to accept NEW connections from remote clients (I was creating a new socket connection for every request). If you allow your connections to persist, the response is appropriately speedy.
Review: Great little device to upgrade older machines for networks - I have purchased quite a few of these, and similar ones that come without the metal housing. I use them for getting data off of machines that have serial outputs, and then broadcast it over the network to a computer that receives the information and stores it in our database. You can configure the unit to be in several different modes (TCP, UDP, etc..). The software that comes with these works ok but you can tell it was written by non-native english speakers and then translated. It is fairly straight forward on how to get this guy to work but you may need to read the instructions more than one time to understand everything they are telling you to do. They also provide some software that installs a virtual COM port on your computer so you can connect to this device (and whatever this device is connected to via its RS485/RS232 connection) over the network as if you computer was plugged straight into the machine. This option has helped me to program PLCs remotely from the comfort of my office and multi-monitor setup. I prefer this option to taking my smaller screened laptop out to the machine in question. Just remember to set up this device for whatever mode you are needing to run it in. I've purchased about a dozen of these guys and will probably purchase another dozen. I just wish they had these on Prime so shipping wasn't so long (or expensive).
