Troubleshooting a JNIOR Serially

Written on: June 22, 2022 12:22 pm

Using the JNIOR should be a smooth process, with only having to connect an ethernet cord to your network and finding it in the JNIOR support tool. Unfortunately nothing always goes perfectly, and maybe you aren’t able to access your JNIOR via beacon or an internet browser. Connecting to a Series 3 JNIOR serially is also a great way to troubleshoot when its no longer responding correctly. Luckily, the JNIOR can be connected to serially to access and hopefully fix this issue.

To access the JNIOR serially, a serial cable needs to be connected between the RS-232 port on JNIOR and your computer. If you don’t have a serial port on your computer, you may need a serial to USB cable instead. Once that is connected, you can then open a command line prompt (You can open an easy to use command line from the support tool under the Tools Tab.) and access the serial connection. When doing this, make sure that the setting for the Serial Connection match what your JNIORs are. If you can’t check, the default settings for the connection are:

  • Baud Rate: 115200
  • DataBits: 8
  • StopBits: 1
  • Parity: None

Once you have set the correct serial settings, you should be able to hit connect and access the JNIOR via the command line! If by chance you are trying to change the JNIOR’s IP because its using one that doesn’t work with your local networks IP, you can change the IP of a JNIOR by using the ‘ipconfig’ command. Simply enter ‘ipconfig -a’ followed by a space and the IP address you are trying to change the JNIOR to. For example, you are trying to change the IP address to, you would use this in the command line: ‘ipconfig -a’.
