2.3 Powering-up the DLPLCRDC4422EVM and preparing for the DLPLCRDC4422EVM to be programmed

Before powering up the EVM, ensure the included DLPLCRDC4422EVM jumpers are in the correct positions. The jumper locations are listed in Section 3.1.1 .

Table 2-1 Reference Designators

Jumper Description (Bold Indicates Default Position)
J11 - Front End 12V Unistalled - Main Board is Powered From its Own AC Adaptor
Installed - Front End Board Provides Power to Main Board
J14 - Blue LED enable or Lamp Ballast Pins 1,2 connected Blue LED Enable
Pins 2,3 connected Lamp Mode
J28 - TDO1 or TDO2 Pins 1,2 connected TDI in to slave is from TDO1 from Master
Pins 2,3 connected TDI in to slave is from TDO2 from Master
J29 - Manual Reset Uninstalled - Normal Operation
Installed - Hold in Reset
J31 - Hold in Boot Loader Uninstalled - Normal Operation

J33 - Vx1 Swap Bit Order Uninstalled - Swapping Bit Order
Installed - Not Swapping Bit Order
J34 - LED Enable Invert Pins 1,2 connected LED_EN inverted
Pins 2,3 connected LED_EN not inverted
J38 - Light to Frequency Sensor or ADC Integrating Sensor Pins 1,2 connected ADC Integrating Sensor
Pins 2,3 connected Comparator Sensor
J40 - High Current Fan 5 or Fan 6 Pins 1,2 connected for High Current Fan 5
Pins 2,3 connected for Fan 6

Jumper J31 is the “Hold BL” jumper. This jumper is used to put the DLPLCRDC4422EVM into boot loader mode, which allows the DLPC4422 controllers to be programmed. Connect this jumper to prepare the DLPLCRDC4422EVM to be programmed.

To power up the DLPLCRDC4422EVM, a 12V, 5A power supply is needed. Ensure the power supply is functional and the switch SW1 on the EVM is set to off before connecting the power supply to the EVM. Connecting the power supply when the switch is in the off position may prevent damage to the DLPLCRDC4422EVM from poor power connections. The image below shows SW1 in the on position.

Once the power supply has been connected to the DLPLCRDC4422EVM, the switch SW1 can be flipped to the “on” position. You can then plug in the USB cable into the board to prepare for programming the board.
