What the APB (Anti-passing back)?
The system is designed for the areas where more security and operation are need, restrict a card at an entry or exit reader based on the status of the cardholder and prevents cardholders from passing back their card to the person behind them.

It can be mounted up to 50 meters from the controller with a simple 3-wire connection. The controller can be configured to operate a single door or two independent doors. The controller also has a RS-485 connection that can be implemented to work with up to 16 controllers connected in a RS-485 network. And it allows the system operates and controls up to 32 doors. In this configuration the PC will require a 311 RS-232/485 convertor to interface to the RS-485 network.

The Secure Card readers are fully small and medium sized and suitable for mounting outdoors .Tampering with these readers will not compromise the systems security. The security is further enhanced by using the Secure Card technology which prevents third party or duplicated cards to gain access.

Overview
The DG-1000M offers one version request command and two memory exchange commands. These memory commands, used with knowledge of the EEPROM layout, allow almost complete control over configuration, holder and transaction memory. The exception to memory access is the automatically-maintained memory contained within address 0x7000 and0x8000. This area contains checksums, configuration backups and integrity markers to ensure the validity of data on the unit.

USB Interface
A device driver has been provided, which when installed will allow low-level communication between the host and the DG-1000M device. This driver has been tested for Windows 2000 and Windows XP. A high level COM interface is also provided which must be registered with Windows. This is a high-level interface, and provides for easy access using application software like Borland Delphi, Microsoft Visual Basic and any others which support the Microsoft Windows COM technology.
