Quick Start Guide

Verify the Jumper

Configuration

Verify the jumper configuration on

each board according to the Jumper

Configurations table found later in this

guide.

Assemble the

Tower System

Assemble the Tower System by matching

primary and secondary sides on the

serial and MCU boards to corresponding

elevators.

Step-by-Step Installation Instructions

In this quick start guide, you will learn how to set up the MED-EKG and Tower System

and run the included demonstrated software. For more detailed infomation, review the

user manual at freescale.com/healthcare.

Connect the

MED-EKG AFE

Connect the MED-EKG AFE to the

medical connector with embedded

electrodes facing upwards.

Download and

Install Software

Download and install IAR Embedded

Workbench 6 for ARM. A 30-day

trial version can be downloaded from

iar.com.

TOWER SYSTEM

Install the

Drivers

Install P&E Micro drivers. The installer

is located in IAR installation folder\arm\

drivers\pemicro.

Connect a

USB Cable

Connect a USB cable from the computer

to the USB port on the TWR-K53N512

board. Wait for drivers to install.

Download the

Application Note

Go to freescale.com and conduct a

parametric search for AN4323. Download

AN4323SW.zip.

Open the

File

Open the file MED-EKG K53.eww using

IAR from \Software\MED-EKG K53\app\

cdc\iar_ew\kinetis.

Step-by-Step Installation Instructions

Continued

Install the

Software

Install the Medical GUI software. It can

be downloaded from freescale.com.

Note: Make sure you have already installed Java®

JDK on your computer. Look for JDK folder in:

C:\ProgramFiles\Java11

Change the

Connection

Disconnect the USB cable from the

TWR-K53N512 and connect it to the

TWR-SER board.

Look for the

COM Number

In the device manager, look for the COM

number assigned to “Virtual Com Port.”

Open the

Medical GUI

Open the Medical GUI and select the

Virtual Com Port from previous step.

Install Drivers for

JM CDC Demo

If the driver is not installed automatically,

open Device Manager and install drivers

for JM CDC Demo. Drivers can be

found here:

• 32-bit version:

C:\Freescale\Medical GUI\Drivers\x32

• 64-bit version:

C:\Freescale\Medical GUI\Drivers\x64

Note: Open the Device Manager by opening

thestartmenu,rightclickingonComputerandselecting Manage. Device manager is on the

left options tree.
