The Cardax FT Intelligent Door Terminal (125 Series)
The Cardax FT Intelligent Door Terminal (125 Series) is a "remote" proximity
reader with text display and an inbuilt Intercom, designed to connect only to
Cardax FT Controller 5000s.
It can be installed as either an entry and/or exit reader and the Intercom enables
communication with the console operator.
The IDT has a back-lit keypad and an inbuilt Liquid Crystal Display (LCD).
The LCD can display both text and graphics to aid the cardholder.
The IDT sends information to the Cardax FT Controller and acts upon
information sent from the Cardax FT Controller. The IDT itself does not make
any decisions.
The "Cardax FT Prox Reader and IDT Cover" can be fitted over the IDT to
prevent the IDT being damaged by vandal attack and to increase protection
against harsh weather. Refer to the "Prox Reader and IDT Covers" Installation
Note (part number 3C4589).

• 1 x cable assembly
• 4 x self tapper pan-head fixing screws
• 4 x screw caps
Note: Once the reader is installed, you require a special tool to open the
Cardax FT IDT (125 Series). Part number C41608 is a kit containing three
delatching tools, of which one is the tool required to remove the cover off the
Cardax FT IDT (125 Series).
Power Supply Requirements
The Cardax FT IDT (125 Series) requires a well regulated power source with
good output filtering. Any "noise" on the power supply may reduce card read
range.
Power required for the Cardax FT IDT (125 Series) is 13.6 V DC (± 15%) with
current at 300mA per reader. This means that the voltage at the reader
terminals, with the reader operating, should be at least 11.6 V DC. It is
recommended you target a minimum of 12 V DC.
Cabling
Prior to installing a Cardax FT IDT (125 Series), the building cabling (RS485
and power) must have been carried out. For further cabling details, refer to
Chapter 2 of the "Cardax FT Installation manual".
To avoid voltage drop in cable runs, it is recommended to run separate DC
power and communications cabling. However, a single cable run is possible as
long as the voltage and current do not drop below the required levels.
EMI Cable Shields
To comply with CE, C-Tick and FCC requirements, and improve noise
suppression, an EMI Cable Shield (ferrite core) should be applied to the cable,
with three turns of the cable running through it. Position the EMI Cable Shield
as close to the entry point of the IDT as possible.

RS485 Communications
High quality twisted pair communications cable with low capacitance -
typically Category 5 (CAT5) cable is used for communications cabling.
DC Power
The maximum recommended length of the DC power cable is dependant on the
diameter of the conductor and the current drawn by the IDT.
Mounting
Note: The Cardax FT IDT (125 Series) has been designed to metric
specifications therefore any imperial measurements provided are approximate
only.
The Cardax FT IDT (125 Series) is designed to be mounted on any solid flat
surface.
However, the card read range is reduced slightly when mounted on or near
metal surfaces.
Height
The recommended mounting height (from the floor to the centre of the IDT)
for the Cardax FT IDT (125 Series) is 1100mm.
Check your local regulations for any variation to this recommended height.

Installation Instructions
1. Considering the recommended mounting height, mark the position where
the IDT is to be mounted.
Note:
It is very important the base of the IDT is flush with, and tight against, the
mounting surface. If you are mounting the IDT on a rough surface, make
the surface as smooth as possible under the IDT and up to 25mm (1 inch)
around the IDT. Failure to do so may mean it could be difficult to remove
the reader at a later date.
2. Drill a 20 mm (3/4 inch) diameter hole for the base extrusion through or into
the mounting surface.
3. Optionally drill the four pilot holes for the fixing screws.
Note:
Six possible mounting points are provided on the base. Ensure the four you
select will mount the IDT securely.
4. Run the building cabling through the base.
5. Fit the base to the 20 mm (3/4 inch) hole and secure it to the mounting
surface using four self-tapper pan head fixing screws (supplied).
6. To comply with the environmental specification, fit the screw caps over
each fixing screw. The screw caps prevent water from entering the Cardax
FT IDT (125 Series) via the fixing holes.
7. Connect the cable assembly to the building cable.
Red = + 12 V DC (nominal)
White = Comms RS485 cable
Blue = Comms RS485 cable
Black = 0 V (GND)
Caution
The Cardax FT System does not require the RS485 cabling to be
polarised but the DC power must be connected to the correct terminals.
8. Ensure the connector is pressed into grommet.
9. Plug the Interconnect PCB onto the connector and ensure it is clipped into
the base.
10. Push the Interconnect PCB / Connector / grommet home into the base.
Firmly clip the Interconnect PCB under the retaining clips in the base.
11. If this Cardax FT IDT (125 Series) is the last unit on this RS485 cable,
connect the supplied jumper across the "RS485 Termination" link on the
main board in the bottom right corner. (Refer to "Component layout" next.)
12. Set the unit address of the IDT as detailed later in this Installation Note.

13. Refit the facia onto the base.
Clip the front over the top edge of the base and press the bottom of the
facia down.
Note:
The pins on the Interconnect PCB in the base of the Cardax FT IDT (125
Series), fit into the slots on the main PCB. The connector should be fitted to
the base, not the facia assembly.

Viewing angle adjustment
The LCD is temperature compensated which enables it to maintain optimum
contrast.
The viewing angle is factory set and you should not need to alter the setting of
the Viewing angle potentiometer.
Removal and replacement
Note: Ensure you follow full antistatic precautions.
Removing the Facia
To remove the facia from the Cardax FT IDT (125 Series) base you need the
plastic de-latching tool (part of part number C41608) shown below. The end of
the tool is used for removing the facia.
De-latching tool
1. Slide the de-latching tool firmly under the bottom of the IDT.
2. Hold the top of the IDT with your fingers and squeeze the de-latching tool
up, towards the top of the IDT 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.
1. Cut a notch in the folded edge of the card similar in shape to the notch in
the de-latching tool as shown below.
2. Slide the card under the bottom of the facia and then use the de-latching
tool with the card as packing.
