April 2004

Before you Begin

Unpack the Prox Mifare Series (Teardrop) reader and check the shipment
contains the following items:

• 1 x Prox Mifare Series (Teardrop) reader base

• 1 x Prox Mifare Series (Teardrop) reader facia

• 1 x printed circuit board (PCB) assembly

• 2 x self tapper pan head fixing screws

• 1 x cable assembly

Installation Note

CAUTION
This equipment contains components that can be damaged by
electrostatic discharge. Ensure both you and the equipment are
earthed before beginning any servicing.

Power Supply Requirements

Power for the Prox Mifare Series (Teardrop) reader is usually taken from the
incoming supply of the device to which it is connected. That is, from the:

• Cardax FT Reader I/O Interface

• Cardax FT Controller 3000

• Cardax FT Universal Reader Interface (Cardax FT URI)

• Cardax Commander Universal Reader Interface (Cardax Commander URI).

The supply at the reader should be 13.6 V DC ± 15%. The current draw is
180 mA per reader. This is in addition to the requirements of any other device
(for example, the URI) powered from the same supply.

Cabling

Prox Mifare Series (Teardrop) readers require a good quality linear power
source. If you do not use the recommended power supply, it may affect the
performance of the reader.

Note: Switch mode power supplies are not recommended as they may reduce

the read range of the Prox Mifare Series (Teardrop) reader.

The Prox Mifare Series (Teardrop) reader uses the Cardax IV communications
system. This means it can be connected to the following Cardax equipment:

• Cardax FT Reader I/O Interface

• Cardax FT Controller 3000

• Cardax FT URI

• Cardax Commander URI

Use 4 core, 0.2 mm2 (AWG 24) cabling with a maximum, nominal capacitance
of 120 pf/m. The maximum external diameter of the cable must not exceed 5
mm (1/5 inch).

With this type of cable, the maximum distance between the Prox Mifare Series
(Teardrop) reader and the device to which it connects is 200 m (650 ft).

Note: You need a special cable terminating tool to connect the building cabling

to the Prox Mifare Series (Teardrop) reader. The tool has a head (Part
No. C861145) and handle (Part No. C861115). You also need a special
tool (Part No. C41611 ) to open the Prox Mifare Series (Teardrop)
reader if necessary.

Mounting Distance Between Proximity Readers

The distance between any 2 proximity readers must be greater than 200mm in
all directions.

Note: The Prox Mifare Series (Teardrop) reader has been designed to metric

specifications. Therefore any imperial measurements provided are
approximate only.

The Prox Mifare Series (Teardrop) reader is designed to be mounted on any
solid flat surface, however metal surfaces can result in a reduced read range.

Note: The grommet through which the cables feed into the base of the Prox

Mifare Series (Teardrop) reader helps to keep the unit waterproof.

Using the mounting dimensions on the back of this Installation Note as a guide,

drill a 20 mm (
mounting surface to a minimum depth of 40 mm (1

/4 inch) diameter hole for the base extrusion through or into the

1

/2 in).

Drill two pilot holes for the fixing screws.

Run the building cabling through the base and grommet.

Fit the base to the 20 mm (3/4 inch) hole and secure it to the mounting surface
using the two fixing screws provided. Note that using other types of screws
could interfere with the electronics.

Note: It is very important that the base of the reader is flush with and tight

against the mounting surface. If you are mounting the Prox Mifare
Series (Teardrop) reader on a rough surface you should make the surface
as smooth as possible under the reader and up to 25mm (1 in) around the
reader. This is to enable easy removal at a later date is required.

Push the socket back into the grommet.

Push the grommet and socket back into the Prox Mifare Series (Teardrop)
reader base.

Check the tape covering the antenna wire solder joints is in position. Install the
PCB assembly into the base, ensuring the connector on the back of the PCB
assembly fits into the socket in the base. The PCB assembly should click into
place.

Fit the facia onto the base by clipping the small lip, inside the facia, over the
top edge of the base and holding the top, press the bottom of the facia down
until it clicks onto the bottom of the base.

Removing the Facia

To remove the facia from the Prox Mifare Series (Teardrop) reader base you
need the plastic de-latching tool (Part No. 41611) shown below. The end of the
tool is used for removing the facia.

De-latching tool

4 Part number 3E1100 R3
September 2004

1. Slide the de-latching tool firmly under the bottom of the Prox Mifare Series

(Teardrop) reader.

2. Hold the top of the Prox Mifare Series (Teardrop) reader with your fingers

and squeeze the de-latching tool up, towards the top of the reader with your
thumb.

3. Lift the facia away from the base.

If the base is not flush to the wall, or the screws have become loose you
may need to pack the space between the de-latching tool and the wall. A
thin piece of cardboard is usually all that is necessary, (i.e. a business card
folded in two).

4. Cut a notch in the folded edge of the card similar in shape to the notch in

the de-latching tool as shown below.

5. Slide the card under the bottom of the facia and then use the de-latching

tool with the card as packing.

Connections

The Prox Mifare Series (Teardrop) reader connects to one of the following:

• Cardax FT Reader I/O Interface

• Cardax FT Controller 3000

• Cardax FT URI

• Cardax Commander URI

Use the cable terminating tool to connect the cables to the socket as described
in the following sections.

Pin number 4 of the Prox Mifare Series (Teardrop) reader connector feeds into
the cable terminating tool first.

Connecting to the Cardax FT Reader I/O Interface

The Cardax FT Reader I/O Interface has connections for up to sixteen Prox
Mifare Series (Teardrop) reader or other Cardax IV readers.

The Prox Mifare Series (Teardrop) reader connects to either plug PA or plug
PB in Groups 1 to 8.

Make the connections from the Prox Mifare Series (Teardrop) reader to the
