Safety instructions
WARNING: INTENDED USE
The VTAP100 equipment is intended for use by suitably qualified integrators, who will integrate the
VTAP100-OEM (PCB) into their own hardware. Although an optional wallbox case can be supplied.
Components mounted on the VTAP100 PCB are not user-serviceable.
WARNING: ESD PRECAUTIONS
We recommend careful handling and storage of Electrostatic Sensitive Devices (ESDs) during
installation. The VTAP100-OEM (PCB) should always be protected by static shielding bags for
shipping or storage.
WARNING: POWER SUPPLY
Use only a MicroUSB to USB cable, or the optional captive USB cable, if any, to connect the
VTAP100-OEM PCB to a PC. (Never connect both at the same time).
Using other cables will invalidate EMC emissions and immunity certifications.
The VTAP100 is rated at 5V DC @ 50 to 150mA for power over USB.
WARNING: USER DESIGNED ENCLOSURES
It is the responsibility of the integrator to ensure that their enclosure design for the VTAP100 retains
compliance with EMC emissions and immunity standards.
Integrators are responsible for evaluating their own end product (including the VTAP100-OEM PCB)
and obtaining separate approvals for the markets in which it will be sold or used.

1  Using this guide
This guide is for first-time users of the VTAP100-OEM.
It contains the information you need about your VTAP100 hardware.
Consult the complete VTAP100 Configuration Guide for more about configuration and maintenance
features, including how to update the firmware on your VTAP100 unit, when a new release is
available.
If you need help beyond what is contained in this guide please contact [e-mail].

2  How the VTAP100 works
With the VTAP100-OEM connected to a PC, simply tap your smartphone against the VTAP100 device.
Your mobile NFC pass will be read and data forwarded to the connected PC.
Of course, the data can only be read if your phone contains a mobile NFC pass, which has been
issued in connection with the Merchant ID(s)/Collector ID(s) and key(s) that are known to the
VTAP100. The unit comes with default values, so that you can test Default operation on factory
settings before you begin customising any settings.
When the VTAP100-OEM is connected to a computer it appears as a generic mass storage device (like
a memory stick). To configure your VTAP100, you simply edit or create text files. These will be read
automatically, and control the operation of the VTAP100. Consult the VTAP100 Configuration Guide
for more detail.
By default the VTAP100 is fully upgradable in the field. However, the VTAP100 can be locked in
software or hardware, before deploying the unit, so that operation is no longer easily changed.
2.1 Default operation on factory settings
Before anyone changes the configuration from its default, you can confirm that the unit is working.
These steps demonstrate that the hardware can detect and interact with an OriginPass mobile
NFC pass, which is ready to work with the default configuration of your VTAP100.
1. Obtain an OriginPass from Dot Origin by visiting https://originpass.com/VTAP/ and add it to
your Google Pay or Apple Wallet.
2. Connect the VTAP100 to your PC, using a USB cable.
3. Open a text editor, such as Windows Notepad.
4. When you tap the OriginPass on the VTAP100:
lPass contents will be displayed in the open text editor.
lThe diagnostic LEDs on the VTAP100 PCB will all flash together.
lYour smartphone may signal with a buzz or beep.
Note: Some Android phones will only interact if their screen is on, although it does not need to
be unlocked. You may need to enable NFC in the settings for the smartphone.
Note: If local security settings prevent or limit the use of removable storage devices, or the
connection of additional keyboards, an administrator may need to alter those permissions.

3  Mechanical installation
The VTAP100 unit for OEM integration comprises a PCB with an integral antenna.
Figure 3-1 VTAP100 components
WARNING: Observe all Safety instructions when installing the VTAP100 PCB.
There is more detailed information in the next section about how to fit the VTAP100 unit inside the
Optional wallbox case, if used.
3.1 Power
Connect the PCB to a PC using only a MicroUSB to USB cable, or the optional captive USB cable, if
any. (Never connect both at the same time).
The VTAP100 is rated at 5V DC @ 50 to 150mA for power over USB.
3.2 Environment
The VTAP100 must be stored and operated under the following conditions:
lAmbient temperature 0 to +50degC
lHumidity 0 to 95% RH non-condensing
lPressure 86-106kPa

3.3 Mounting points
The PCB has 2.7mm diameter mounting holes for fixing the unit. Either use the 50mm spaced holes
on the snap-off tabs, or remove those tabs and make use of the three holes on the body of the
board. Use 2-4 small nuts and bolts.
Figure 3-2 VTAP100 PCB mounting holes
The user’s smartphone should be able to tap within 10mm of the antenna on the PCB. The antenna
position should be clearly marked and easily accessed, so that users can position their smartphone
appropriately.
3.4 RS232 connection
The PCB has a special connector J1 (an 8 pin, 2mm pitch header connector) which can be used to
attach a captive cable with a matching crimped cable-end plug.
The standard connector fitted to the PCB is a Hirose DF11-8DP-2DS male header plug with shroud.
The matching socket is the DF11-8DS-2C.

Figure 3-3 VTAP100 captive power cable or RS232 connection
The connector J1 includes both USB and RS232 signals, as follows:
Pin Function
1 GND
2 USB D+
3 +5V supply
4 USB D-
5 RS232 RXD (input)
6 Reserved (sense input)
7 RS232 TXD (output)
8 Reserved (sense GND)

Figure 3-4 Typical RS232 cable
A typical RS232 cable has the following D9 connector pinout:
Pin Function
2 TXD
3 RXD
5 GND
9 +5V supply
The VTAP100 requires a 5V power supply. This can either be provided via:
lJ1 (pins 1 and 3) and the serial cable/host (not all RS232 devices have 5V on pin 9), or
lother USB connectors on the VTAP100 PCB.
Some serial cables have a separate DC 5.5/2.1mm barrel connector to supply power. In these
cables, typically, the centre pin is +5V and the outer barrel is GND.
3.5 Optional wallbox
The optional wallbox for a VTAP100 is 86mm x 86mm and 25.5mm deep.
Figure 3-5 VTAP100-USB
You can design and affix your own branded label to the unit. The size of the label recess is 72.33 x
72.33 mm with 4mm radius rounded corners as shown below. If you need help branding units do
contact [e-mail].

4  Hardware lock to prevent firmware or configuration
change
You can lock the VTAP100 so that its firmware and configuration cannot be changed. You can either
do this in software or hardware.
A software lock leaves some files visible. A hardware lock means that the VTAP100 will no longer be
detected as a composite USB device.
You can use a hardware lock provided the jumper labelled LOCK (close to the MicroUSB connector)
remains accessible on a VTAP100-OEM.
Connect a jumper across LOCK on the PCB to lock the device, preventing firmware or configuration
changes.
Figure 4-1 Jumper positions on VTAP100 PCB V3a
When you start the VTAP100, the presence of this jumper means the connected PC will not detect a
USB mass storage device. The VTAP100 will only be detected by the PC as a keyboard (or keyboard
and virtual COM port).
At any time you can remove the jumper across LOCK. When you restart the VTAP100 it will be
detected as a USB mass storage device and you will be able to make firmware or configuration
changes again.

5  Disposal
For safety and sustainability, it is the responsibility of the integrator to ensure that when equipment
containing a VTAP100 reaches the end of its life, it is recycled in accordance with WEEE Regulations
within the EU.
VTAP100 (PCB and cables) should not be disposed of in general waste. If you wish
to discard electrical and electronic equipment (EEE), please contact your supplier
for further information.
