Brightlight LED Controller iad Users Manual Revision D Introduction The BrightLight LED Controller provides precise and repeatable settings of the light intensity The intensity can be set manually using the controller mounted rotary switch or remotely from a computer The light intensity is controlled using PWM Pulse Width Modulation technique The light source is turned on and off rapidly and the proportion of on and off time is varied to achieve an apparent variation in the overall intensity While the light source is on the controller is supplying an accurately controlled amount of current through it Because the instantaneous current level is the same at all different intensity settings the color temperature of the light is constant regardless of the intensity setting Additionally PWM technique results in minimal power losses in the controller resulting in a cool running system Set Up Instructions for Enclosed Controller 1 40042 amp 1 40045 1 Attach either the USB or RS 232 communication cable supplied to the appropriate receptacle on the back of your Brightlight board and to a USB or RS 232 port on your PC If you are using RS 232 please take note of which COM port is being used 2 Connect the power supply provided with your enclosure 12vDC 2 1mm power jack Note When turned on the controller intensity and brightness level will always reset to 0 following a brief flash regardless of prior settings It is advised
