Basic Control Commands
Basic Command Definitions
‘P’ Power Control
Turn on / off, or toggle the power state of the ClarityHD8x8:
^P 0$ Turn off power if power is not locked on.
^P 1$ Turn on power.
^P 2$ Turn off power regardless of “locked” state.
^P 3$ Turn on power and lock it on -- only a “P 2” command can turn off power.
^P +$ Toggle power
^P ?$ Query for current setting
Response String:
^=P n$
Where:
n = Current power status, 0=Off, 1=On, 3=Locked On. (A value of ‘2’ is never returned.)
The power lock and unlock can be used to keep a controller from turning off the ClarityHD8x8.
Drivers should be written to only use the “P 0” and “P 1” commands to turn on and off the
ClarityHD8x8. This allows users to override the driver’s logic by manually issuing the “P 2” and “P 3”
commands.
By issuing a “P 3” command (lock power on), the ClarityHD8x8 will be turned on, and locked. Only a
subsequent “P 2” command will turn off the ClarityHD8x8, The “P 0” and “P 1” commands will be
ignored.
