First you’ll have to properly configure your controller. Once that’s done, you can remotely connect to it.

  • Remotely connect to your Lenze controller

Configure your Lenze controller

This chapter shows how to easily configure your Lenze controller for remote access.

  • Open a simple text editor program (i.e. Notepad).
  • Type the controller’s IP address, subnet mask, and default gateway into the newly opened file. An example is given below. The IP address needs to share the subnet of your x500 but cannot match their exact IP address. The subnet could for example be “192.168.5”, meaning the last figure “.1” can vary anywhere from 1 to 254 as long as it’s different from the x500. The subnet mask needs to be the same as the x500, which is usually 255.255.255.0. The (default) gateway should be set to the IP address of the x500.

  • Save the file as “ip.txt” onto the SD card of your Lenze controller (root directory) using a card reader.
  • Insert the SD card into the Lenze controller. Then (re)boot the controller. During the boot sequence the controller uses the “ip.txt” file to configure itself.

Configured
Your Lenze controller is now ready for remote access.
