NCL31010 Evaluation Kit
User's Manual
IEEE 802.3bt Complete PoE Connected
LED Driver Power Solution Kit
NCL31010GEVK
General
The NCL31010GEVK kit allows easy implementation
and evaluation of a Power−over−Ethernet powered LED
Luminaire Controller that is able to operate with an assigned
power level up to 51 W.
The NCL31010REFGEVB evaluation board is based on
the Complete PoE Connected LED Driver Power Solution
NCL31010 (U2) with integrated PoE PD interface
controller, dual synchronous step−down DC/DC converters
for the main 3.3 V VDD system supply as well as an
auxiliary supply VDD2 and a current mode buck DC/DC
controller designed to operate as a LED driver.

Basic Interconnections
The NCL31010REFGEVB board is designed as a PoE
splitter: having a PoE−enabled Ethernet port (labeled "PoE
IN") as input while passing through the data to another
Ethernet port (labeled "ETH OUT").
The NCL31010REFGEVB reference design board is
Ethernet Alliance PoE Certified and YellowDott ready.

EVAL BOARD USER'S MANUAL
Quick Start Guide
Step 1: Mount the Arduino
unpowered microcontroller board with Arduino UNO
compatible headers.
Step 2: Configure the jumpers on the Arduino Adapter
Shield. Figure 2 shows the jumper settings for a
microcontroller board with Arduino UNO R3 compatible
headers using PWM for Analog Dimming.
Figure 2. Jumper Settings
Step 3: Mount the NCL31010REFGEVB on the Arduino
Adapter Shield (NCL31010AASGEVB).
Step 4: Connect the black Ethernet patch cable to the
Ethernet connector J1 (labeled "ETH OUT") and to the
Ethernet connector on the microcontroller board.
Step 5: Connect the LED load to connector J4 (labeled
"LED") while observing the correct polarity (cf. black and
red wires in the picture on the left). Ideally, the LED load has
a 0.65 A to 1.4 A current rating with a 16 V to 38 V forward
voltage range.
Step 6: Insert the Ethernet cable (cf. blue cable in the picture
on the left) coming from the PSE in the Ethernet connector
J2 (labeled "PoE IN").
If the PSE powers up the system, the green 3V3 VDD LED
should be ON and the orange MPS LED should be blinking.
The status of the remaining LEDs depends on the jumper
settings.
