Quick Start Guide
After unpacking the MAX32560 EVKit please follow these steps to prepare for testing. NOTE: More
detailed instructions for each step are found in the following sections.
•Verify the device has not been damaged in shipping, Figure 1 shows the device as shipped
•Download and install Tera Term Serial Terminal Emulator on Test PC
•Plug wall wart supply into outlet and connect barrel connector to J6
•Re-verify connections etc. then move SW4 to ON position, verify Leds light
•Connect included USB cable from Test PC to USB socket CN1
•Start Tera Term, and connect to the COM port the EVKit enumerated as (EX: COM5, or COM23)
•Press the space bar until main DTE menu is displayed as shown in Figure 2.
•For ease of testing, C. Continuous Polling from the Analogue Menu or Begin Digital Loop Back
Mode from the Digital Menu may be used exclusively. Both implement the standard EMV Loop
Back Test Mode.

Detailed Setup and Configuration
This section is a reference for setting up and configuring the EVKit and DTE for EMV testing.
Tera Term Serial Terminal Emulator
Tera Term is a Serial UART Terminal Emulator for windows PCs. This guide is written using version 4.82,
it is available for free download here:
https://en.osdn.jp/projects/ttssh2/downloads/60733/teraterm-4.82.exe/
Project home page can be viewed here: https://ttssh2.osdn.jp/index.html.en
After downloading and installing Tera Term, launch it from the Start Menu. Select Serial Port… from the
Setup menu item as shown in Figure 3.

This will display the Serial port setup window shown in Figure 4. After the EVKit is Powered and the USB
cable is connected, a COM port will show up here in the Port menu. It is recommend to check this menu
first before connecting the DUT as other serial COM ports may be available on the test PC. When the
DUT USB is connected a new COM port will be shown in the Port menu. NOTE: The Serial port setup
window must be restarted to see newly available serial COM ports.
Figure 4: Tera Term Serial Port Settings
If necessary consult the Device Manager from the Windows Control Panel, and observe the entries
under Ports (COM & LPT) to determine the correct COM port number.
After identifying the correct port, and IF the DUT is powered and connected to the PC, select the COM
port. In Figure 4 COM23 is selected.
Configure the baud rate to 115200 as shown in Figure 4, and verify the remaining settings match Figure
4
Finally press OK to exit the Serial port setup menu. Click in the Tera Term main window and press the
space key repeatedly to cycle to the DTE Top level menu as shown in Figure 5.
If menu is not displayed consult the Trouble Shooting Section at the end of this manual.

Power Supply Setup and Configuration
NOTE: If for some reason the wall wart supply is not to be used refer to Appendix A for setup and use of
the optional bench power supply.
1. Ensure switch SW4 is in the OFF position
2. Connect wall wart supply barrel connector to J6 as shown in Figure 6
3. Plug wall wart into outlet
4. Move SW4 to the ON position. The power supply LED’s should lite as shown in Figure 6.
The device is now correctly powered up, proceed to USB Cable Installation.

USB Cable Installation
After the powering the EVKit, connect the included Micro USB cable from the test PC to the EVKit
connector CN1 as shown in Figure 7.
NOTE: The MAX32560 EVKit uses the FTDI USB to UART device. Windows comes with the driver for this
device by default and after installation it should automatically enumerate as a newly available COM
port.
If any issues are encountered with DTE menu access refer to the troubleshooting section.

DTE Overview
The DTE implemented for the MAX32560 is a serial UART driven menu. It supports all required test
sections as detailed in PCD_L1_Device_Test_Environment_v25a_161115.
The main, top level menu shown in Figure 2 and Figure 8, has three entries for the required test sections
of EMV Level 1. Note, the EVKit does not support any Level 2 functions.
•TTA L1: Analogue
•TTA L1: Digital
•TTA L1: Pre-Validation
The interface is straightforward, press the key shown for each menu item to select it.

Analogue Test Menu
The Analogue Test Menu shown in Figure 9 provides convenience functions for use by the EMV
Analogue Test Engineer to send specific commands. It also provides loopback functionality if desired,
both one with a settable number of loops, and one that will loop continuously until a key is pressed to
exit the loop.
NOTE: Per PCD_L1_Device_Test_Environment_v25a_161115 all menu options other than 1, require the
Carrier be enable first. The Carrier status is shown at the top of the Analogue Menu.
Figure 9: DTE Analogue Menu
All Analogue commands other than C. Continuous Polling, will be executed in a loop the number of times
specified by the Loop Setting. This defaults to 1 at boot, and may be changed in the L. Change Loop
Settings menu. Only numbers from 1-9999 will be accepted. The current setting for number of loops is
shown at the top of the Analogue Menu.

Troubleshooting
DTE Top Level Menu is Not Displayed/USB Issues
•As the USB cable is connected after the EVKit boots, the menu may be printed before Tera Term
connects to the DUT. Press the space bar a few times to redisplay the DTE Top Level Menu.
•Sometimes it is necessary to unblock the USB cable, and reattach. Then press space bar to
redisplay the DTE Top Level Menu.
•If the USB port fails to Enumerate, unplug cable, exit Tera Term and try again
•If COM Port does not appear in Device Manager under Port (COM & LPT), Attempt the “Scan for
hardware changes” from the “Action” menu in Device Manager.
•The serial UART to USB interface chip gets a new USB handle whenever the host PC is power
cycled or then EVKit board is power cycled. Any preexisting session via Tera Term may no longer
be valid. Exit Tera Term then reconnect. Avoid having the Test PC sleep or reboot during test
session.

Appendix A: Bench Power Supply
A Bench Power Supply may be used instead of the included wall wart supply.
It should be plugged in and connected to the DUT board as shown in Figure 6.
Configure the bench power supply as follows:
Set the output voltage to 5.0V.
Set the output current limit to 1.0A.
If supported, set the voltage display to manual with a range of at least 5V.
If supported, set the current display to manual with a range of at least 1A.
NOTE: When applying power to the DUT, be sure to leave power off for a minimum of 3 seconds
before powering again. Quick cycling of the power supply could damage the DUT.

Appendix B: Wall Wart Power Supply
NOTE: If for some reason the wall wart supply is not to be used refer to Appendix A for setup and use of
the optional bench power supply.
1. Ensure switch SW4 is in the OFF position
2. Connect wall wart supply barrel connector to J6 as shown in Figure 6
3. Plug wall wart into outlet
4. Move SW4 to the ON position. The power supply LED’s should lite as shown in Figure 6.
The device is now correctly powered up, proceed to USB Cable Installation.
