3.3 *0: Unlocked Mode Control Operator Access
3.3.1 Set control operator switches
The *0 command allows access to control operator switch groups 8 and 9 which are not
accessible using the control operator prefix. These groups help to implement controller
security by controlling write access to controller data and control operator access to the
other 8 groups.
The format of this command is
*0<g><i><s>
where:
<g>
specifies the group number. Valid range is 0 to 9.
<i>
specifies the switch number. Valid range is 0 to 7.
<s>
is optional. If present, it is the new state of the switch. Valid values are
0 and 1.
Upon receipt of a valid *0 command without the state, the controller will say the current
state of the selected control operator switch.
Example:
Sending the command *000 will inquire of the state of control operator
group 0 item 0, and the controller will read back the current state: “control zero point
zero is enabled.”
See Section 4 for more information about control operator switches.
