Smartec ST-NC120B Network Controller

The Smartec ST-NC120B network controller is designed for one two-way access point, two readers. Supports multiple identification methods: by card, card and code, card or code. It runs under the pre-installed Timex software.

Specifications:

• The number of cardholders is 30,000.
• The number of events is 100,000.
• The number of time zones is 256.
• The number of access levels is 256.

The controller is compatible with all readers with the Wiegand 26 and Wiegand 34 interfaces and with most codebase panels. It is based on a 32-bit 400 MHz processor, Embedded Linux OS.

Functionality:

• Control of locks with normally open and normally closed contacts.
• Unlock mode for the first card.
• Support for prohibiting re—entry is called Antipassback.
• Gateway mode, only with the door sensor connected.
• Multi-card access mode (multi-person rule).
• Pass code support under duress.
• Redundancy of communication, connection via Ethernet and RS-485.
• System freeze prevention is a hardware watchdog timer.

It provides the possibility of long-term autonomous operation without connecting to the server. The controller is equipped with 32 MB RAM and 256 MB Flash memory.

The controller includes enhanced security measures in the form of hardware protection against:

• Overcurrent, voltage overload.
• Reverse polarity of the power supply.
• Voltage overload across all inputs/outputs.
• Voltage overload across all communication ports.

The ST-NC120B is equipped with status indicators for connection and data exchange over TCP/IP, data transmission and reception over the RS-485 bus, data reception over the Wiegand interface, and the status of the lock relay. It is equipped with DIP switches for setting the device address in the RS-485 bus, power inputs for the controller and lock, inputs for connecting the lock relay, exit button and door position sensor, additional output for connecting alarm actuators, doorbell, etc.

The controller is supplied in a box case. The operating temperature range is 0 ° C... +55 °C. Power supply — DC 12 V. The power consumption excluding readers is no more than 300 mA. The size of the controller is 160×106 mm, the case is 345×275×70 mm.
