Output mode 1: Analog output 0-4

just connect the red wire to 12V and black wire to ground

And any infrared source might also interfere the detection

Industrial wireless control

Data is entered seriallythrough DSA or DSB and either input can be used as an active HIGH enable for data entry throughthe other input
