Pins 7 through 12 of connector J1 must be connected to GND. ONBOARD PWM DIMMING · · · · OPERATION: Onboard PWM configuration as shown in Figure 1 allows the user to control display brightness by controlling the onboard PWM generator. The user is responsible to provide an analog control signal. A dimming ratio up to 100:1 is possible with this configuration. DIMMING: Dimming is accomplished by applying an analog voltage to the Control Pin (J1-15 J1-15). Display brightness is modulated by controlling the Control Pin voltage as shown in Graph 1. ENABLE/DISABLE: The driver may be enabled or disabled (turned on and off) by applying a DC voltage to the Enable Pin(J1-13 J1-13). Enable Pin on and off levels are specified in the Operating Characteristics section of the data sheet. The driver can also be enabled by floating the Enable Pin. Pins 1 through 6 of connector J1 must be connected to +Vin, between 10.8 and 18 Vdc. Pins 7 through 12 of connector J1 must be connected to GND. Pin 14 may be left floating or pulled up. EXTERNAL PWM DIMMING · · · · OPERATION: External PWM configuration as shown in Figure 2 allows the user to control display brightness with an externally generated PWM signal. The user is responsible to provide the PWM signal. A dimming ratio up to 10,000:1 is possible with this configuration. DIMMING: Dimming is accomplished by applying a PWM signal to the PWM Pin (J1-14 J1-14). PWM on and off levels are specified in the Operating Characteristics section of the data sheet. Display brightness is modulated by controlling the PWM duty cycle as shown in Graph 2. ENABLE/DISABLE: The driver may be enabled or disabled (turned on and off) by applying a DC voltage to the Enable Pin (J1-13 J1-13). Control Pin on and off levels are specified in the Operating Characteristics section of the data sheet. Pins 1 through 6 of connector J1 must be connected to +Vin, between 10.8 and 18 Vdc. Pins 7 through 12 of connector J1 must be connected to GND. page 3 of 5.
