Example

: Write to Auto-Tune control register (start Auto-Tune) on

Command Code Explanations

Controller (Node) Address: N

When more than one controller is on the serial communication bus, a

unique controller (node) address must be assigned to each unit. The address

range extends from 0 to 99. This is defined in the controller configurations.

To communicate with a specific controller, the address code N followed by

the controller’s address value must start a command string. A controller with

an address of 0 does not require the node address command. Controllers with

an address greater than 0 will respond to transmit commands by sending their

address followed by the requested data.
