USR-TCP232-306 Serial to Ethernet Converter LAN Ethernet TCP/IP to RS232 RS485 RS422 Converter2

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.

Good product, fulfilled my communication need.

I spent a half day with this. and got nothing working. All I wanted is to put a RS232 serial data into the one side and connect a RJ45 Ethernet into the other and have it be transparent. I have used a Digi International Port Server TS4 for years and it is simple to configure, doing just that. I was looking for something in a less expensive price range.

Bought three, really impressed with the versatility and options. After several months of use, they no longer reconnect reliably. A power cycle is required to get them to auto-connect again. All three behave the same and once they start doing this, they fail almost daily. That's unacceptable.
