Configuring Automatic Power Controls
PT-12 enables you to configure the following automatic power controls for your
connected display:
•Configuring Display Auto Sleep on page 8.
•Configuring Display Auto Power on page 8.
Configuring Display Auto Sleep
As long as there is an active source signal, the connected display remains ON. When
the active source becomes incative, a 5V signal is sent to the display to delay it from
going into sleep (standby) mode. PT-12 enables you to enable/disable and set the
delay time before the 5V output cuts off.
To configure the auto sleep delay:
•Set DIP-switch 6 and 7 to the required position (see Configuring Using DIP-
Switches on page 7).
Configuring Display Auto Power
PT-12 features display auto power via CEC communication. This feature turns ON a
display that is in sleep mode when an active signal is detected and turns it OFF (shuts
down) when the active signal becomes inactive. PT-12 enables you to enable/disable
display auto power and to set the delay time before the display is turned OFF.
Enabling/Disabling Display Auto Power
To enable/disable the display auto power feature:
•Set DIP-switch 5 to the required position (see Configuring Using DIP-Switches
on page 7).
Setting Delay Time for Display Auto Power Shutdown
When the display auto sleep delay (see Configuring Display Auto Sleep on page 8) is
set to a shorter time than the display auto power delay, the 5V does not shut OFF
until display auto power turns OFF the display.
To set the delay time before display auto power shutdown:
•Use the AV-SWITCHING-MODE command (see Protocol 3000 Commands
on page 15).
Defining EDID Lock
PT-12 enables you to define whether to enable the EDID values to be passed through
the device and changed automatically to follow the output or to lock the EDID so that
it will not be affected by changes on the output.

When the unit
receives the LDEDID
command it replies with
READY and enters the
special EDID packet
wait mode. In this mode
the unit can receive only
packets and not regular
protocol commands.
If the unit does not
receive correct packets
for 30 seconds or is
interrupted for more than
30 seconds before
receiving all packets, it
sends timeout error
