Connector
The interface connector is a Molex 0.30mm (.012") Easy-On™ Type Right Angle, SMT, ZIF, Bottom Contact Style Receptacle
part number 54393-2192. See
Interface Connector on page 1-2 for details.
Connector Pinout
Pin Signal Description
1 Ground Power and signal ground.
2 LED Current Control PWM Input - Controls the LED current. A pulse width modulated signal based on a frequency of 7.5K Hz
reduces the current of the LED power supply. The relationship of current to duty cycle is inversely pro-
portional (the longer the duty cycle, the lower the current). Leave this pin unconnected if not using this
feature.
3 Ground Power and signal ground.
4 Horizontal Sync (H Data Valid) Output - Definition varies according to the setting of the image registers. For the configuration defined in
this document, this signal is used as a data valid window. Polarity of this signal is selectable in register
address 0x01, Bit 1. Hand Held Products setting is 1 = active high window.
5 Vertical Sync (V Data Valid) Output - Definition varies according to the setting of the image registers. For the configuration defined in
this document, this signal is used as a data valid window. Polarity of this signal is selectable in register
address 0x01, Bit 2. Hand Held Products setting is 0 = active low window.
6 Aimer On Input - Active high on this line enables the LED power supply and turns on the 2 aiming LEDs. This line
may be pulse width modulated many times per horizontal line (based on pixel clock) in order to reduce
power.
7 Illumination On Input - Active high on this line enables the LED power supply and turns on the 4 illumination LEDs. This
line may be pulse width modulated many times per horizontal line (based on pixel clock) in order to
reduce power.
8 Power Enable Input - Active high enables the imager. A low on this line places the imager in a power down state.
