Quick Start
This chapter details the steps to power-up and use the DLP NIRscan EVM spectrometer.
2.1
Power-Up the DLP NIRscan EVM
The DLP NIRscan is ready to use, out of the box. Follow these steps to power up, connect the EVM to a
computer, and access the home screen.
1. Connect a 12-V DC power supply to the input power supply connector.
2. An LED next to the power connector on the spectro board lights up green. The fan starts and the
DLPC350 and Sitara processor start booting. After 5 to 10 s, the DLPC350 is confirmed to be running
its firmware if green LED D3 (in the middle of the spectro board) starts flashing a heartbeat
(approximately one flash per second). A blue LED next to the Sitara Micro-USB connector also
illuminates to indicate that the Sitara power supplies are up.
3. The EVM Sitara processor runs a webserver, which provides display information to the user through an
HTML browser such as Mozilla Firefox
®
, Google™ browser, Safari
®
, or Internet Explorer
®
. Connect the
USB port of the computer with the browser to the EVM through the micro-USB connection at location
14.
4. Many computers ship with RNDIS drivers installed, which are required to use Ethernet-over-USB. After
plugging-in the micro-USB cable in step 3, if there is no RNDIS driver installed on the computer, the
software typically prompts the user before searching for the driver. After the RNDIS driver is installed,
start a browser session. The following steps install the RNDIS drivers on Windows 7 or Windows 10 in
case they are not installed.

5. Enter http://192.168.0.10 in the URL window at the top of the browser screen: . The first time the cable
is connected on a PC, the DLP NIRscan enumerates. If the browser does not connect within 30
seconds, or the browser times out, the user may need to refresh the browser once or twice to provide
more time for the system to enumerate, load the RNDIS driver, and register its IP address with the
host PC.
6. When connected to the DLP NIRscan, the NIRscan Home Screen displays in the browser window (see
).
