Configure node address

Before anything else make sure pin 2 is grounded on your node.

Set the following:

  • Set port to /dev/ttyUSB0 (or whatever shows in the previous step)
  • Set port speed to 38400
  • Tab to Connect button and press Enter.
  • Tab to Address field, enter unique number for this node.
  • Tab to 'Set address' button and press Enter
  • Tab to 'Store to EEPROM' and press Enter

The address is now stored, you can disconnect and unground pin 2.

As a side note: if you have several nodes connected (eg if they are on a rs485 bus), make sure you only set one address at a time (only one node can have its pin 2 grounded at a time) to avoid any confusion.
