4.5.5 RS-485 Wiring
Note
• There are four RS-485 interfaces, which are for connecting ID card reader, IC card reader, QR
code scanner, fingerprint and card reader, card recycler, fingerprint reader, and face recognition
terminal. Take the wiring of RS-485 card reader as an example.
• When connecting the RS-485 interface with a card reader, the default entrance address is 1 and
the exit address is 4.
• If there are more than 1 RS-485 devices connected, the RS-485 ID cannot be conflicted.
4.5.6 RS-232 Wiring
Note
There are three RS-232 interfaces (UART4, UART7, and UART8). UART7 and UART8 can connect QR
code scanner, and card recycler, while UART4 can connect QR code scanner, card recycler, and face
recognition terminal.
