1. INTRODUCTION
MG2475-EVK(Evaluation Kit) is the development kit based on MG2475 which is an SOC
chip including RF transceiver and 8051 micro controller, by RadioPulse.
This document explains how to start with MG2475-EVK.
Additionally, this document includes how to install CP210X driver, how to download the
firmware using RadioPulse Device Programmer and how to measure PER(Packet Error
Rate) of MG2475.
Therefore, a user can easily measure the performance and RF characteristics of MG2475.

2. DEFINITIONS
EVB : Evaluation Board.
LM2475-EM : Evaluation Module of MG2475.
CP210X : USB-To-UART Converter
PER : Packet Error Rate
RSSI : Received Signal Strength Indicator. It specifies the strength of the received
packet.
ED : Energy Detection. It specifies the energy level of the current RF channel.

3. CP210X DRIVER INSTALLATION
CP210x on EVB is USB-to-UART controller. The driver for CP210x should be installed first,
because it makes a PC to recognize the EVB.
The following is the installation steps.
(A) Execute CP210X_VCP_Win_XP_S2K3_Vista_7.exe to install CP210x VCP drivers.
(B) At the final step of installation, check “Launch the CP210x VCP Driver Installer”and
press “Finish”.
If it is not checked, it can be reinstalled later by executing
“C:\SiLabs\MCU\CP210x\Windows...Vista_7\CP210xVCPInstaller.exe”.
(C) Press “Install”. The “CP210x USB to UART Bridge Driver”is installed on the PC.
(D) If the driver is not installed, it can be installed manually when CP210x is connected to the
PC. The driver is located in “C:\Program Files\Silabs\MCU\CP210x”folder.

4. OVERVIEW OF EVB
Figure 1. TOP view of MG2475-EVB
The main elements of EVB are as follows;
MG2470-EVB : Evaluation Board for MG2475
LM2475-EM : Evaluation Module for MG2475
Main Power SW: Power switch
Reset SW: Reset switch
ISP SW: ISP switch
USB0-UART0 : USB port for UART0.
USB1-UART1 : USB port for UART1. The firmware should be downloaded via this
port.

5. CHECK COM PORT
Connect MG2475-EVB to PC using “USB1-UART1”port of EVB. Set the power switch to
“USB_ON”. Then, The PC recognizes EVB as COM port. The number of COM port is
checked as follows.
(A) Right-click on “My Computer”icon and select “Properties”.
(B) Select “Hardware”tab.

NOTICE
If two or more EVBs are connected to one PC and the CP210x’s IDs are same, all expected
ports are not displayed because the number of ports are same. Then, the CP210x’s ID
should be unique by using AN144SW application released by Silicon Labs, the maker of
CP210x. The application is available from www.silabs.com
