Note
●
There are four RS-485 interfaces, which are for connecng ID
card reader, IC card reader, QR code scanner, ngerprint and
card reader, card recycler, ngerprint reader, and face
recognion terminal. Take the wiring of RS-485 card reader as
an example.
●
When connecng 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
conicted.
4.5.6 RS-232 Wiring

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 recognion terminal.
