Turnstile access Controller is a control module designed for OEM and aftermarket integration into turnstiles for access control applications. It is part of a custom-designed Ethernet network with a connection to the ticket server.

The Turnstile Controller Module is an access control device designed for integration into all types of turnstiles. The device controls the opening of the turnstile gate. It supports two USB barcode scanners, one RS-232 barcode scanner, and an RFID card reader. The device is custom-designed to connect to the ticket server via a local Ethernet network. It supports 10/100BASE-T Ethernet and DHCP client protocol for network addressing. An external keyboard can be connected for manual input of unreadable tickets. An RGB LED array provides visual feedback and event indication. An external buzzer is supported, with different melodies programmable for each event. An integrated real-time clock and calendar store timestamps for event logging, with LOG files saved on an SD card. An additional configuration server enables remote control of all settings, firmware updates, and direct command execution. The available 64 Mbit memory allows storage of a local ticket list, enabling access without ticket server confirmation. This feature enhances overall system reliability, ensuring the device remains fully functional in autonomous mode during network disruptions. A 2.8" TFT LCD display is supported for image output, including event titles, scanned information, and access granted/denied messages. The device firmware is based on the FreeRTOS real-time operating system, with tightly integrated USB Host and Ethernet drivers, an embedded TCP/IP stack, and dedicated firmware modules. The LCD display drivers are custom-designed and integrated with the graphics library, enabling animations and user interaction via a resistive touch panel.

The configuration server enables remote control of devices, remote configuration of all configurable parameters, and firmware updates over the air. The firmware update process allows updating all integrated non-volatile memory, including the real-time clock and calendar backup SRAM memory. The firmware update procedure is fully encrypted and supports controlled updates for specific devices with specific firmware versions. The update files are downloaded to the SD card interface and then used during the update process. The configuration server also manages the update of images on the LCD display, which are shown during access events. Additionally, the server integrates a database for storing the hierarchical structure of users and groups across multiple levels. All turnstiles at the specific object, group, or company level can be controlled simultaneously.
