New Controller For One Access Point Smartec ST-SC101 For Connecting A Reader With An IButton/Wiegand Interface

The ST-SC101 programmable controller from Smartec has appeared on the market. It is designed to create autonomous access control points, so-called single-door ACS, with a database for 1000 users.

It is designed to work with external reading devices, for connection of which it is equipped with Wiegand and iButton interfaces, and supports a convenient mode of automatic memorization of identifiers. In addition, this iButton/Wiegand controller provides for the selection of the operating mode of the lock control relay (pulse or trigger).

The ability to work with Wiegand and iButton readers ensures the universality of the controller when organizing a single-door autonomous ACS. Thanks to the presence of a Wiegand input, various external smart card readers can be connected to the ST-SC101, and it supports Wiegand 26–42 formats, which are the most common in such systems. In addition, the controller is compatible with iButton (or Dallas Touch Memory) readers of the DS1990A standard, which read information from an electronic key, the so-called "tablet". In this case, the reader is installed outside, and the controller is inside the protected premises, which ensures a high level of security.

ST-SC101 programming is performed using a master card, which is assigned when the device is first used. This iButton /Wiegand controller allows you to configure two master cards at once in one session for the convenience of subsequent work. To add new identifier codes to the controller database and delete current ones, you should use one of the active master cards. When connecting an iButton reader, a master key is used in a similar way. At the same time, ST-SC101 supports the mode of automatic addition of new users, during which the codes of all read identifiers will be added to the controller memory (the lock will be unlocked each time).

Support for pulse or trigger mode of operation of the lock relay allows integrating the ST-SC101 controller into various access control systems. If after user identification it is required to keep the lock open for a short period of time (maximum up to 127 sec) and then automatically lock, the pulse mode of operation of the lock control relay is selected. For facilities where the door must be in the unlocked state for a long time, for example, during working hours, the iButton/Wiegand controller allows setting the relay to the "trigger" mode, i.e. both unlock and lock the lock by identification.
