LX1250TI User Manual 13
The following table defines the factory set values for the adjustable
parameters.
*Backlight retains previous brightness settings.
Auto Power On
The display automatically turns on when power is restored after a power
failure and maintains all operational settings. Note: “on/off” refers to the
LCD panel and the backlight inverter.
Standby Mode
If no video is present, after 10 seconds, the display powers off
(will power back on once video is detected.)
No Burn-in during Signal Loss
The AMLCD will not maintain any static self-generated images
(such as a “no video” text box when video is not present), thus avoiding
image burn in.
2.1.2 Details of Command Implementation
All serial commands must be compatible with the Pixel works PW Host
protocol defined in the Pixel works application note AN#77. Refer to AN
#77 for protocol details.
The physical layer used for data exchange is RS232. No handshaking is
used. Pin 3 of the DB-9 connector on the display is data transmitted from
the host (Tx); pin 2 is data transmitted from the display and received by
the host (Rx).
