Why CoreStation 20?

    Suprema's CoreStation 20 (CS-20) is a next-generation RFID-only access controller designed to deliver secure, scalable, and efficient access control solutions. Engineered specifically for RFID-based environments where biometric authentication is not required, the CS-20 supports a wide range of RF card types depending on the connected reader. Optimized PoE+ support and simplified configuration ensure easy installation and integration into existing infrastructure. The CS-20 is ideal for organizations seeking a high-performance, RFID-centric access control system.

What is New About CoreStation 20?

1. RFID Access Control Panel

• Supported RS-485 Slave device list: X-Station 2 (non-fingerprint model only), XPass 2, XPass D2

2. Connect maximum 4 RS-485 Slave RFID readers at RS-485 Port 0 and RS-485 Port 1

• You can connect a maximum of 2 RS-485 Slave devices (RFID readers) per RS-485 port. (Total maximum of 4 RS-485 Slave devices per 1 CS-20/CS-20P device.)
• However, you CANNOT use the "RS-485 port" without the port number on the top for the RS-485 Slave RFID reader connection.
• NOTE that you CANNOT connect RS-485 Slave devices and Wiegand readers at the same time.

3. Enlarge your installation with Suprema's biometric readers via the Intelligent Slave feature.

• Suprema's biometric (fingerprint, face, or visual face) readers cannot be an RS-485 Slave device of CS-20.
• However, you can connect using the Suprema biometric readers' Intelligent Slave feature (matching at the readers).

4. Easier network configuration via CoreStation Setup Manager

• CS-20 also supports CoreStation Setup Manager.
• Relevant Article: [BioStar 2] CS-40 Setup Manager Release, Suprema CS-40 SETUP Manager
  • The CoreStation Setup Manager is a web-based service that allows you to check the connection status of the CoreStation from anywhere after the wiring is completed. This feature can be used when your initial setup.

5. Expandable card compatibility with SAM Slot (CS-20P only; firmware customization required)

• Enhance your security authentication with secure smart card authentication through the SAM Slot.
  • Firmware customization is required for further support. Please contact the Suprema Sales team (Contact Suprema Sales).

6. Intelligent Input Mapping

• The AUX Input on the top of DI-24 is pre-configured for Tamper, AC power fail, and fire inputs from the Fire Alarm Panel.

What is Different from CoreStation (CS-40)?

   CS-40 supports biometric (fingerprint and face) matching. However, CS-20 focuses on RFID matching, which can reduce the cost and complexity. Also, CS-20 can offer the relay power from itself, so you can connect a maximum of 2 relays without installing a separate power resource.
