Greetings all!
Here is a quick guide on how to use or test your Serial over IP device quickly and easily using a simple TELNET application. In this example, we will be using PuTTY but any TELNET utility should do. This is great for communicating with your device or even performing a simple loop-back test.
This is applicable to our NETRSxx series as well as our new xx-SERIAL-ETHERNET series (any device with TELNET support).
To do so, simply:
→ Step 1: You’ll want to first make sure that our Network Serial device is well powered and connected to your network. Ensure you know it’s IP and that it is reachable through ping. If this is for a first-time install, please refer to your product’s instruction manual (Drivers & Downloads) first.
→ Step 2: Please launch your Terminal app and input our Network Serial’s IP in TELNET mode and proceed to connect.
- If it does not connect, please make sure that you are using the right port. For example, our NETRS2321P defaults to 23 while our I13-SERIAL-ETHERNET defaults to 5000.
- If it connects, but you see garbled data, our Network Serial’s baud rate is likely not matching your target serial device’s required speed. Simply use our Web Interface to change the default baud rate.
→ Step 3: You should now be able to view or enter commands through the Terminal. If you are doing a loop-back test, ensure that pin2 and 3 are now shorted in order to see an echo of all your text back.
This is an easy way to test or use a Network Serial device without needing to install or setup Virtual COM ports. If you need a quick Terminal access to configure a network switch or change the settings on a serial display, this is an excellent way to do so from any computer on the same network.
