The output registers report the sensor states, stamps, and measurement values and decisions. You can
read multiple output registers using a single Read Holding Registers or a single Read Input Registers
command. Likewise, you can control the state of the sensor using a single Write Multiple Register
command.
Control registers are write-only, and output registers are read-only.

Register Map Overview
Control Registers
Control registers are used to operate the sensor. Register 0 stores the command to be executed.
Subsequent registers contain parameters for the commands if applicable. The Gocator executes a
command when the value in register 0 is changed. To set the parameters before a command is executed,
you should set up the parameters and the command using a single Multiple Write register command.
