Troubleshooting a JNIOR Serially

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 a great way to troubleshoot when it’s no longer responding correctly. This post will briefly go over how the JNIOR can be connected 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 the 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 settings 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 it’s 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, if you are trying to change the IP address to 10.0.0.201, you would use this in the command line: ‘ipconfig -a 10.0.0.201’.
