Problem in Reading value of sensor connected to Labjack T4 using vb6

iHello,

I have a triangulation sensor to detect an object connected to Labjack T4. I want the sensor output to read in my VB application. I have downloaded the LJM VB  in zipped form and have installed and cconfigured it. 

However when I run the VB code there is RUN button clicking on which I am getting  Info only like

LJM Library Version =  1.1802 Opened a LabJack with Device type:  4, Connection type:  1, Serial number:  440010743, IP address: 0.0.0.0, Port:  0, Max bytes per MB:  64 LJM_eWriteName:     DAC0 =  2.5 V 

I want to read sensor output in textfield. But which pin needs to be traced on labjack. have no idea. what sensor outputs that too.

For e.g. I want 1 in textfield when sensor detects object and 0 otherwise.

PLs help me.

Thanks
