## Questions & Answers

**Q: A review said this unit will not work with US power outlets, is this correct?**
A: This is not true. We just sent a UK adapter to a batch of products last year,  but we corrected the shipment in time and resend the correct US adapter to all customers.  But All the equipment currently in the inventory is Equipped with the correct US adapter, You can buy it with confidence

**Q: Can this be used to monitor a console port on a server?**
A: Yes, should work perfectly for that.  Connect this box to the RS232 port on the server then you can telnet into the  box and have virtual connection over IP to the serial port.

**Q: Could i use a tcp/ip client to connect to this device then send and receive data as if i am connected to the serial port directly?**
A: It could work as TCP server so your TCP client device can connect to this device directly. But you need to configure the relevant parameters according to the application via webpage or setup software of USR-TCP232-302. Thanks

**Q: What is the size of the dc barrel connector? i want to use this with a poe+ to 5v converter and need to make sure i get one with the correct connector**

## Customer Reviews

### ⭐⭐⭐⭐⭐ Well worth the price for its capability
*by W***R on August 24, 2020*

This thing is great, if you have a device that is RS 232 and you want to be able to use it over an ethernet IP network you should buy one of these and try it out. They’re not that expensive and odds are it will work with your device. I have been able to take devices that are quite old and do not support any form of ethernet communication but do support cereal communication by modem This thing is great, if you have a device that is RS 232 and you want to be able to use it over an ethernet IP network you should buy one of these and try it out. They’re not that expensive and odds are it will work with your device. I have been able to take devices that are quite old and do not support any form of ethernet communication but do support serial communication by modem and actually talk to them using this device and their older software. It’s stable and works well. And I was very pleased to pay this low price for that capability.

### ⭐⭐⭐ Yet to be defined
*by M***A on April 15, 2021*

I was disappointed to discover that there were no instructions included in the packaging. The device has a website listed that may have instructions.I am eager to find time to install and test the device on my network/ KPC2 Packet controller.I will upgrade my listing when I have had a chance to play with it.

### ⭐⭐⭐⭐ Works great, a bit difficult to setup
*by J***L on March 17, 2020*

I love these! I this for the price they are awesome. The only reason I cannot give it 5 stars is setup is a bit of pain. I read about that before I bought it and thought "I'm smart and technically inclined. I'll have no problem". Alas that was not the case. The English translation in the software have some problems and there are quirks (such as each device showing up 4 times) you have to learn how to circumvent. Having that said, once setup, these things are great! It is really nice to have RS232 access across the house without cables.
