Setting ABO Time
The ABO (Auto Backlight OFF) function is used to automatically turn off the backlight if neither
key entry nor touch-panel entry is permitted for a certain period of time. This function is used to
set the ABO time. Enable ABO by selecting a number between 1 and 15, which corresponds to
a period of between 20 seconds and 5 minutes.
SYNTAX
int SYS_SetAboTime(int nValue);
INPUT
nValue = ABO time
0 Not activate ABO
1 to 15 Activates ABO in specified number x 20 seconds.
OUTPUT
= 0 Normal
= -1 Parameter error
= -3 VxD not registered (for IT-2000W only)
Note:
This function will be implemented by a software timer. Therefore, the period until the backlight is
actually turned off has an error of +/- 10 % associated with it.
