4. Control Operator Commands
The NHRC-10 supports 80 different control operator settings arranged into 10 different
groups of 8 “software switches.” Each software switch represents an item in the controller
that can be set to either on or off. Every switch is addressed by naming the group, then the
item number. There are 10 groups of 8 items each.
The format for all control operator commands is:
<ctl-op-prefix><group><item><state>
<ctl-op-prefix>
The control operator prefix assigned by the repeater operator.
(See Section 3.5 for information on programming command
prefixes.)
<group>
The group code for the switch to set or inquire. The valid range
for <group> is 0 to 7. Groups 8 and 9 can only be accessed with
the programming *0 command. (See Section 3.3 for
information about *0: Unlocked Mode Control Operator
Access.)
<item>
The item number to set or inquire. The valid range for <item>
is 0 to 7.
<state>
is optional. If present, it is the state (1=on, 0=off) to which the
control operator switch is to be set.
When <state> is not present, or after a successful control operator command that sets the
switch state, the controller will respond by speaking “control <group> point <item> is
<state>”, where group and item are the group and item numbers selected, and <state> is
either of the words “enabled” or “disabled.”
For example, to set group 0 item 0 to enabled, the following command would be sent:
<ctl-
op-prefix>001.
The controller will respond by saying “control zero point zero is enabled.”
All 80 of the control operator switches are saved when the controller’s state is saved. Saved
state 0 is the power-up state, so if you want to make your changes to the control operator
switches be restored after a power failure, it is important that the controller’s state be saved.
See Section 3.4 for information on the save state command.
