7.2 Notes
x When referencing registers using Modbus functions, registers belonging to multiple categories cannot
be read simultaneously using a single message. To reference registers belonging to multiple categories,
read them using multiple messages by classifying the corresponding addresses by category.
x The explanations in this specification apply commonly to RC controller Series models supporting
“Protocol M.” For the specifications and other items specific to each model, refer to the RC controller’s
operation manual that comes with the applicable controller.
