PT-L communication driver's read schedule input 'READ' one line.

2. Write settings

You can control PT-L series controller by using write settings.

Digital Write

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             don't care.

3)  ADDRESS           don't care.

4) Extra1                    write command.

 PWR - power ON/OFF,

AMT - mute ON/OFF,

VID - Set Video Signal,

RG1 - Set RGB1 Signal,

RG2 - Set RGB2 Signal.

5) Extra2                    don't care.

Write example 1)

PORT:0,  station:0, ADDRESS:0000, Extra1: PWR,  Extra2 :

The setting parameter shown above is power On/Off setting example of PT-L Projector.

Analog Write

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             don't care.

3)  ADDRESS           don't care.

4) Extra1                    write command.

 AV - setting of volume, ( outptu value = 0 ~ 63 ).

5) Extra2                    don't care.

Write example 1)

PORT:0,  station:0, ADDRESS:0000, Extra1: AV,  Extra2 : , Output value = 50

The setting parameter shown above is volume setting example of PT-L Projector. setting volume value = 50

Note) Write command except PWR can set only Power On status.
