Chapter 55-3F-5-25.2 Various Controls5.2.1 Controlling the Laser Activation Timing5.2.1.1 Laser Emission ON/OFF Control 0010-7720iR2016 / iR2020 / iR2016i / iR2020iThe purpose of this control is to turn ON/OFF the laser diode (LD) in response to video signals.The DC controller PCB sends laser control signals (CNTRL0, CNTRL1, and CNTRL2), which are used to switch between laser driver operation modes, to the laserdriver IC along with video signals (VDO1, /VDO1, VDO2, and /VDO2). The laser driver IC controls laser emission (ON/OFF) according to the combination ofCNTRL0, CNTRL1, and CNTRL2 signals.The following table shows combinations of laser control signals (CNTRL0, CNTRL1, and CNTRL2).T-5-45.2.1.2 Laser Emission ON/OFF Control 0011-2155iR2016J /The purpose of this control is to turn ON/OFF the laser diode (LD) in response to video signals.The DC controller PCB sends laser control signals (CNTRL0, CNTRL1, and CNTRL2), which are used to switch between laser driver operation modes, to the laserdriver IC along with video signals (VDO1, /VDO1).
