MeshConnect
LED Daughter Card Demo
April 2010
Purpose of Demo: To demonstrate use of MeshConnect modules, together with Cree LED and Linear LED Driver.
Hardware Required:
•One Computer (used only for programming evaluation boards)
•USB cable
•Two Evaluation Boards (including the MeshConnect Module.)
•One MeshConnect LED Daughter Card
•Four AA batteries
Assembly & Set-Up Sequence:
1. Connect each eval board to a PC using a USB cable. The Master Board will be controlling
the Slave Board, which will hold the MeshConnect LED Daughter Card.

2. For first time use of evaluation boards, you will need to load the USB drivers
onto your computer.
3. Program SNAP onto each eval board, making sure that each one has a
unique MAC address.
Note: For instructions on how to program SNAP, see the SNAP Quick Start Guide, found on
your kit CD or on www.CEL.com under 8012.15.4; Software Downloads
(Link: http://www.cel.com/downloads.do?command=showByType&group=5)

4. Up-load scripts onto each eval:
a. The name of the script to up-load for the Master
Board is “LTC-SWITCH.py”.
b. The name of the script to up-load for the Slave
Board is “LTC-LIGHT.py”.
c. See the SNAP Quick Start Guide for step-by-step
instructions on how to up-load scripts.
d. The scripts can be downloaded from CEL’s website
at:
http://www.cel.com/downloads.do?command=showB
yType&group=5
e. The scripts will need to reside in a folder called
“CEL”, which you may need to create.

2. Resetting each Eval Board: Hold down
Switches 3 & 4, together with EITHER Switch 1
(for white LED 1) OR Switch 2 (for amber LED
2); then press and release the RESETB
button. The board will reboot and five seconds
later, LED 1 (white) or LED 2 (amber) will
remain lit.
