2.2 Setup the kit

The kit is delivered already assembled, but in case it is received dis as sembled or is disassembled during operation, the next chapters describe how to assemble it.

2.2.1 TWR-Elev Primary and Secondary boards

It is important for the next steps to differentiate the Primary and Secondary TWR-Elev boards. Depending on the version, the name of the board can be written:

“Secondary board” or “Primary board” on the inner side (i.e the side with the 4 female PCI connectors).

If the name is not printed on the board, the Primary can be found by its marking “A side expansion port” and “B side expansion port”, while the Secondary board embeds “C side expansion port” and “D side expansion port”

2.2.2 Assemble the Hardware

The TWR-LCD has to be connected on the outside of TWR-Elev Primary board.

Fig 8. TWR-LCD connected on TWR-Elev primary

TWR-POS-K81 and TWR-POS-PN5180 have to be connected in the TWR-Elev PCI slots.

The primary and secondary connectors of each board have to be connected respectively on the primary and secondary TWR-Elev boards. The side can be recognized by its marking on each board as shown in Fig 9.

2.3 USB Connections

The Kit presents 3 USB connectors:

• One Mini USB on the TWR-Elev board

• One Mini USB on the TWR-LCD board

• One Micro USB on the TWR-POS-K81 board

See Fig 14 and Fig 15 for each connector’s location.

In order to operate the Tower Kit, both the Micro USB, underneath TWR-POS-K81 board, and the Mini USB on the TWR-ELEV board have to be used.

Micro USB has to be connected to the host computer (running the high-lev el app lic atio n) and the TWR-ELEV mini USB has to be connected to a power source (either from a computer USB or from a power socket USB). Both are needed to ensure the Kit will have enough power to operate in all modes.

2.4 TWR-ELEV Power Switch

A switch is mounted on the TWR-ELEV board. This switch is used to turn ON or OFF the power supply from the TWR-ELEV USB connector.

For the SLN-POS-RDR to operate, the switch has to be in the ON position (top) shown in Fig 16, otherwise there will be no power from this TWR-ELEV connector.

3. Demonstration

3.1 Setup the environment

After the Hardware is assembled and connected, the computer has to be set up in order to operate the payment demonstration: the TWR_POS_K81 module embeds a USB to Serial converter, accessed through the mini USB port connected to the computer.

When this USB is connected, the host computer should display an unknown device in the device manager.

The dedicated driver for this device has to be installed so that the computer gets a new COM port that will be used to connect to the POS Reader Solution Kit. This can be done following the below steps:

Locate the .inf file for this driver: It is delivered with the software package. It is called

fsl_ucwxp.inf and is located in the folder

“boards\twrposk81\demo_apps\payment_demo\cardtek_ihs_app”

Open the device manager Locate the unknown device. This should be a device with a Yellow Bang, named

“MCU VIRTUAL COM DEMO”. See

Fig 17. Right click on this device, and choose “Update Driver Software” Select “Browse my computer for driver software” “Let me pick from a list…” “Show all devices” then “Next” “Have Disk” Click “Browse”, navigate to the folder containing the above mentioned .inf file, and

select this .inf file. Windows should propose a Virtual COM port (see Fig 18). Select it then click “Next” Note that Windows may show a warning saying that the driver is not digitally signed.

To install it anyway, the computer must be configured to disable driver signature

enforcement. If the computer is not correctly configured, it can be done following Microsoft help. E.g.

https://msdn.microsoft.com/en-us/windows/hardware/drivers/install/installing-an-

unsigned-driver-during-development-and-test

Note that the above link may not give the exact process depending on the computer

OS version. Windows may then show some messages asking to confirm that you want to install

this driver. Accept by selecting “Install this driver Software anyway” Windows will install the driver When the driver is installed, it may happen that Windows shows a message

informing that the driver cannot start. In such a case, unplug then plug back the USB

connection. This should restart the driver, so that it is seen as running (no error) in

the device manager (see

Fig 19).
