Troubleshooting Guide - What to do when it isn’t working?
www.startech.com/I13-SERIAL-ETHERNET
In this article, we’ll review the steps to follow when troubleshooting our I13-SERIAL-ETHERNET devices (and similar models), along with common causes of issues. The content is divided into sections to help isolate the root cause and identify appropriate solutions.
Web Interface accessibility
Is the web interface accessible? If not:
- Make sure you are using “http://x.x.x.x” in the address bar. Not specifying the protocol may cause modern browsers to default to “https://x.x.x.x” (and hide it entirely).
- Try pinging the device (e.g.:
ping 192.168.5.245or it’s assigned custom IP). - Ensure the Ethernet link/activity LEDs are on or blinking. If not, could be a power issue.
If you are still unable to reach the device, perform a factory reset (hold the front-panel reset button for approximately 5 seconds until the LEDs turn off and on again), then follow the setup guide.

Loop-back test
The next step to follow if the device is otherwise well accessible through its web interface would be to perform a Loop-back test (click HERE to find out how). If the loop-back test fails, validate the following:
- Ensure you are using a conductive material to short pin 2 and 3. Try different parts if needed.
- If you have a device with more than 1 port, ensure you are on the right port (and test the other ports).
- Double-check that the device is in the right setting for your access method (TELNET, TCP, UDP). If possible, try by local COM port software method as well (or by TELNET if already testing by software).
- Try on a different computer or terminal app.
UART Configuration
If the device does respond well over Loop-back test but not in your application, then the issue is likely based on configurations:
- Please verify that your application or system is set to the right COM port or TELNET address (should match the one used when testing by loop-back).
- Consult your serial equipment manual to ensure the UART settings are correctly configured on the device (Baud rate, Data bits, Parity, Stop bits, Flow control, etc.).
- Make sure you are using the right cable type for your application (straight-through vs. cross or null-modem cable).
- Please always refer to your serial equipment’s documentation to validate settings and required wiring. Ensure you are using the right protocol (RS232, 422 or 485).
These steps should cover the majority of issues when using a serial network device. If you still need assistance, please contact our Support Team, preferably while in front of the equipment in question.
