Power
Connect the PCB to a PC using only a MicroUSB to USB cable.
The VTAP100-PAC-W model can alternatively be powered by connecting it to an access controller, using the Wiegand connector supplied . If the VTAP100 is being powered through its Wiegand connection, you can still make an additional USB data connection to a PC, provided that the PC is already powered. (This avoids the risk that the USB data connection is driven to too high a voltage.)
The VTAP100 is rated at 5V DC (typ. 110mA, max 150mA) for power over USB.
VTAP PRO models:
The VTAP100-PRO-BW comes with a USB cable for power. It can also be used to access the mass storage drive (if enabled), USB keyboard emulation and USB COMPort. (Refer to USB wiring for how to disconnect this cable, should you prefer to power the unit from an expansion board, after configuration.)
The VTAP100-PRO-POE comes with an RJ45 cable, with a female RJ45 connector, for both power and network connection.
A micro USB cable could be connected to provide an alternative source of power during local configuration. (Refer to USB wiring for how to connect this.)
If the optional VTAP100-PRO-EXP1 expansion board is used, the VTAP100 PRO reader can be powered from the I/O board, using the 0.5m EXP cable provided. It does not matter whether the reader is already receiving power in another way. The I/O expansion board itself is powered through its 2 pin Molex connector, rated 9‑15V DC (typ 600mW). (The VTAP reader cannot be used to power the expansion board.)
The connecting cable between the VTAP PRO I/O expansion board and VTAP PRO reader allows you to mount the VTAP100 PRO reader and the I/O expansion board at a distance from each other, for instance with the VTAP PRO reader mounted on counter top and the I/O expansion board under the counter.
Environment
The VTAP100 must be stored and operated under the following conditions:
-
Ambient temperature -25 to +70°C (-13 to 158°F)
-
Humidity 0 to 95% RH non-condensing
-
Pressure 86-106kPa
PCB Mounting
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 holes on the body of the board.
If you need to remove the tabs, we recommend carefully following the perforations provided to avoid damage to the board, using a vice and pliers, or a PCB cutter.
Use 2-4 small nuts and bolts to mount the board securely.
VTAP100 PCB mounting holes - v4a or v5 Hardware
The VTAP antenna should not be mounted more than 10mm deep within your enclosure (measuring from the antenna surface to the enclosure surface), so that a user’s smartphone will be able to come close enough to the antenna for reliable reading.
The antenna position should be clearly marked and easily accessed, so that users can position their smartphone appropriately. Be aware that antennas are positioned differently in different makes of smartphone. Apple iPhones often have antennas near the top and Android phones are more likely to have an antenna in the middle.
CAUTION: Mounting a VTAP board near metal can reduce performance of the VTAP reader, because metal can distort the NFC field. Never allow a metal surface between the VTAP reader and the user's phone or card. If you have to mount the VTAP reader near metal, you should ensure the separation is:
-
at least 6mm and insert a ferrite sheet between the VTAP reader and any metal surface behind the reader, or
-
at least 25mm separation between the VTAP PCB and any metal
Testing should be performed in the proposed mounting location, as other devices and structures in close proximity could affect pass reading performance.
Optional RS-232 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 crimp housing.
The standard connector fitted to the PCB is a Hirose DF11‑8DP‑2DSA male header plug with shroud. The matching crimp housing is the Hirose DF11‑8DS‑2C.

The connector J1 includes both USB and RS-232 signals, as follows:

Typical RS-232 cable
A typical RS-232 cable has the following DB9 female connector pinout:

9 |
+5V supply (if any) |
A PC or terminal RS-232 connector is usually DTE (data terminating equipment), typically a male DB9 with transmit (TXD) on pin 3 and receive (RXD) on pin 2. The appropriate connecting cable is then a DCE (data communications equipment) female DB9. TXD and RXD pins are swapped between the DCE and DTE devices, so that the transmit pin on one connects to the receive pin on the other.
The VTAP100 requires a 5V power supply, but not all RS-232 devices have 5V on pin 9. Your options are:
-
If your RS-232 connector provides 5V power on pin 9, disconnect the USB cable before making the serial connection, then power will be provided by J1 (pins 1 and 3) and the serial cable/host.
-
If your RS-232 connector does not provide 5V power on pin 9, retain a USB connection in addition to the serial connection.
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.
