Mode: Select SC203+IC

  • Elegant design suits office, home or factory settings
  • 30 000 ID cards and 50 000 transactions stored locally
  • TCP/IP, RS232/485 and USB-Host link to PC software
  • Full lock, alarm, exit button and door sensor control
  • Wiegand in/out enables master-slave or panel reader modes

Access control for small sites

The SC203+IC is a networked RFID controller that manages door locks, alarms, exit buttons and door sensors for houses, small offices or factories. It supports both ID cards as standard and IC cards as an option, storing up to 30000 users and 50000 transaction records on the device itself. Operation can be handled locally via the LCD or remotely through PC software.

12V DC power requirement

The unit runs on a 12V DC supply, so the site must provide that voltage at the mounting location before installation can begin. If the existing wiring delivers a different voltage, an additional step-down transformer or power supply will be needed to avoid damaging the controller.

Wiegand wiring and network setup

Installers connect the lock, sensor, exit button and alarm to the access control interface, then link the Wiegand in and out ports for master-slave configurations or third-party panel integration. Communication uses TCP/IP, RS232 or RS485, and the USB host port handles bulk data transfers; incorrect Wiegand polarity or mismatched baud rates on the serial links are the most common causes of a non-responsive system.

Questions about this item

How many staff members can the 30000 ID card capacity actually support in daily use?

The controller stores up to 30000 unique ID cards, so each enrolled employee uses one slot; total staff on the system cannot exceed that figure.

What does the TCP/IP, RS232/485 and USB-Host mix limit when linking to a PC or network?

TCP/IP handles LAN communication, RS232/485 provides serial links for longer cable runs, and USB-Host is restricted to local data import or export of templates and logs.

What mounting clearance does the unit need for the lock, sensor, exit button and alarm terminals?

The device requires wall space for its own housing plus cable entry room for the 12 V DC supply and the five access-control wires (lock, sensor, exit button, alarm, door bell).
