Access controller with 30000 card capacity

The SC203 is a door access and time-attendance terminal that stores up to 30000 ID cards and 50000 transaction records. It supports both ID and optional IC cards and communicates over TCP/IP, RS232/485 and USB-Host. Built-in lock, alarm, exit-button and door-sensor interfaces handle full door control.

Suits small offices needing standalone access

The unit works well for sites that want local LCD operation plus central management via network or serial links. Wiegand input allows a master-slave reader setup while Wiegand output lets the device act as a reader for an external panel. Buyers who need biometric verification or higher user counts should consider other models.

Surface-mount installation

Mount the controller, wire 12 V DC power and the lock, sensor, button and alarm contacts to the marked terminals. Configure network settings and user data on the LCD or upload them from PC software through TCP/IP or USB. Common issues include incorrect Wiegand polarity when linking readers and exceeding the 30000 card limit during enrolment.

Questions about this item

Does the SC203 need a separate 12 V DC power supply to operate?

Yes, the unit requires a 12 V DC source; the power supply itself is not included in the box.

Can I keep my existing Wiegand reader and use the SC203 as the master controller?

The Wiegand‑in port lets you connect an external reader so the SC203 acts as the master in a master‑slave setup.

How do I confirm the controller is communicating with the PC after wiring TCP/IP?

The LCD will show a network status icon and the PC software will list the device once the TCP/IP link is active.
