Mode: Select SC203+ID

  • Elegant casing suits professional environments
  • 30000 ID card capacity handles large workforces
  • 50000 transaction records store extensive attendance history

Access terminal for small sites

The SC203 handles time attendance and door access for houses, small offices and factories. It stores up to 30000 ID cards and 50000 transaction records. Operation is possible on the built-in LCD or via PC software.

Limits of TCP/IP and serial links

Communication uses TCP/IP, RS232 and RS485 plus a USB host for data transfer. The USB host is for upload and download only, not for live network traffic. Wiegand in and out allow master-slave setups or connection to a control panel.

Straightforward wall mounting

The unit mounts directly on a wall and connects to a 12V DC supply, lock, door sensor, exit button and alarm through the access control interface. No special tools are required. The operating range is 0 °C to 45 °C at 20 to 80 percent humidity.

Questions about this item

Should I choose the ID-card model or the optional IC-card version?

The standard unit reads ID cards and stores up to 30000 users; an IC card reader can be added as an option if you need Mifare or other contactless formats.

What does the 50000 transaction capacity mean for daily use?

It holds 50000 clock-in or door events before the oldest records are overwritten, so a small office can run weeks without downloading logs.

How do the TCP/IP, RS232/485 and USB-Host interfaces limit real-world connectivity?

TCP/IP links the terminal to your network for live monitoring, RS232/485 connects legacy controllers or a PC, and USB-Host lets you move user templates and logs with a flash drive when the network is down.
