Originally introduced as an AX100 component, the data transfer unit is available as an option, to
transfer database changes from the PC to the controller without the need for a direct PC
connection.
After the initial programming, the AX100 controller can be disconnected from the PC and the
controller will perform all access control functions autonomously. The controller can open and
close doors without computer intervention.
The PC is where all the system configuration and data management is stored. The optional data
transfer unit (DTU) enables the data that has been entered at the PC to be downloaded to the
controller without the need of a physical PC connection.
One data transfer unit can be used for up to 255 controllers, or a total of 16,000 cardholders
distributed over multiple controllers in a single download. E.g. 10 controllers each with 1,600
cardholders can be downloaded in one go, without the need to go backwards and forwards
between the PC and controller. Similarly 255 controllers each with 60 cardholders can be
downloaded to each controller without returning to the PC. Only valid cardholders are
downloaded to the controller.
The Data Transfer Unit is fully plug and play at the controller and PC. The AX200 PC software
allows multiple DTU’s to be used.
Connecting the DTU
Make sure the COM port settings are enabled in
System Settings • General Settings. Connect the
power supply to the communication cable at the 15
way connector. Plug in the 9 way connector to the serial port of the PC. Start the AX200
software. Connect the DTU to the RJ45 connector, follow the on-screen instructions of the install
wizard.
After configuring the DTU, the following window will appear on the screen. This window contains
the list of the doors that require download.
