3.1 Quick Start

This chapter offers a quick start guide of how to:
• Download the associated software
• Connect the DLP660TEEVM, DLP470TEEVM or DLP780TEEVM to the DLPC4420AEVM
• Power up the DLPC4420AEVM
• Program the DLPC4420AEVM to display a SPLASH image on the DMD
• Troubleshoot issues
3.1.1 Downloading the Software
Before programming the DLPC4420AEVM, make sure the DLPC44xx GUI and DMD firmware have both been
downloaded to the PC. The DLPC44xx GUI allows for operation of the EVM and the DMD firmware is required
according to DMD being utilized. If the DLP660TEEVM is being used with the DLPC4420AEVM, then the
DLP660TE firmware is needed. Otherwise, if the DLP470TEEVM is used, then the DLP470TE firmware is
needed.
The DMD firmware and DLPC44xx GUI can be found under the Software Development tab on the product pages
on TI.com. Please see the product pages for the DLP660TE, DLP470TE, DLP780TE, and DLPC4420.
3.1.2 Powering-up the DLPC4420AEVM and Preparing for the DLPC4420AEVM to be Programmed
Before powering up the EVM, make sure the included DLPC4420AEVM jumpers are in the correct positions. The
jumper locations are listed in
Jumper
J11 - Front end 12 V
J14 - Blue LED enable or lamp ballast
J28 - TDO1 or TDO2
J29 - Manual reset
J31 - Hold in boot loader
J32 - Vx1 Swap P/N
J33 - Vx1 swap bit order
J34 - LED enable invert
J38 - Light to frequency sensor or ADC integrating
sensor
J40 - High current Fan 5 or Fan 6
Jumper J31 is the Hold BL jumper. This jumper is used to put the DLPC4420AEVM into boot loader mode, which
allows the DLPC4420 controllers to be programmed. Connect this jumper to prepare the DLPC4420AEVM to be
programmed.
To power up the DLPC4420AEVM, a 12 V, 5 A power supply is needed. Make sure 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 can prevent damage to the DLPC4420AEVM
from poor power connections. The image below shows SW1 in the on position.
