Power, Switching, and Muting

Basic Control Commands

These commands are all that are needed for basic control of the Zektor Switch and includes power on/
off, remapping sources to zones.

'P' Power Control

Turn on / off, or toggle the power state of the Zektor Switch:
^P 0$
^P 1$
^P 2$
^P 3$
^P +$
^P ?$
Response String:
^=P n$
Where:
= Current power status, 0=Off, 1=On, 3=Locked On. (A value of '2' is never returned.)
n
The power lock and unlock can be used to override the a controller's on/off logic, keeping a controller
from turning off the Zektor Switch.
Drivers should be written to only use the "P 0" and "P 1" commands to turn on and off the Zektor
Switch. This allows users to override the driver's logic by manually issuing the "P 2" and "P 3" com-
mands.
By issuing a "P 3" command (lock power on), the Zektor Switch will be turned on, and locked. Only a
subsequent "P 2" command will turn off the Zektor Switch, The "P 0" and "P 1" commands, issued by
the controller, will be ignored.

'SZ' Set Zone(s) -- Analog Audio Switch

This command is used to map sources to any number of analog zones, on audio switch.
The zones for the analog audio switch are:
1-128 = Depending upon model number.
The source numbers for the switch, depend upon the switch's model number, and the Extended I/O set-
ting.
For a full listing of source numbers see: "The Default (Native) Source Numbering" on page 31, and
"The Extended I/O mode" on page 37.
The different forms of the 'SZ' command are:
^SZ @zone,@zone,in$
^SZ @zone,+$
^SZ @zone,-$
