Before you begin
Shipment contents
Open the box and check that the following items have been supplied:
• 1 x Cardax FT IDT Mifare Base.
• 1 x Cardax FT IDT Mifare facia assembly (includes printed circuit boards,
processor, display and keypad).
• 1 x interconnect printed circuit board.
• 1 x copy of this installation note.
• 1 x cable assembly.
• 4 x pan-head self-tapping screws.
• 4 x screw caps.
• 1 x M4x12, tamper-resistant, Torx-head machine screw.
Software
The IDT requires version vMP3.00 or later of software code, which you can
download from your Cardax FT Command Centre Installation CD-ROM. If
the CD-ROM does not have vMP3.00 or later of IDT code on it, the code can
be downloaded from the Cardax website.
Once you have the correct IDT code, it then needs to be downloaded to the
IDT. To do this, refer to "Adding a new version of Device Software" for the
procedure, in the Cardax FT Command Centre User Guide (part number
C209000).
Power Supply Requirements
The IDT draws 300 mA from a 13.6 V ±15% DC supply. This means that with
the reader operating, the voltage measured across pins 1 and 4 on the
interconnect printed circuit board should be at least 11.6 V. It is recommended
that you dimension the cable to provide a minimum of 12 V at the IDT while it
is operating.
Use a well-regulated DC supply that incorporates good output filtering. Switch
mode power supplies may reduce the card read range due to the electrical noise
generated by the power supply switching circuits.
Building cabling
Run the building cabling before installing the IDT. Refer to Chapter 2 of
Cardax FT Installation Manual for cabling details.
Over short distances, you may run one cable carrying both the communications
and DC supply. Over long distances, run separate cables for the DC supply
and communications. In each case, verify that the correct supply voltage is
present at the IDT.
