HIKVISION DS-K3Y501SX Series - Access Control Board Serial Port ID Description

• For any requirements, the door lock can control the door barrier status of the third party. D1
controls the barrier opening for entrance, while D2 controls the door opening for exit. For
details, see Barrier Control Relay Output Mode .
• C3 and C4 in the event input can also be people counng interface. C3 controls people counng
for entrance, while C4 controls people counng for exit. When the access control board detects
signals in C3 and C4, the people number will be accumulated. For detailed informaon about
people counng and people number, see Conguring People Counng Parameters in User
Manual of iVMS-4200 AC Client

4.5.4 Access Control Board Serial Port ID Descripon
You can use the jumper cap on the access control board to switch the interface communicaon
mode. For details about switching between RS-232 and RS-485 communicaon type, see Switching
RS-485/RS-232 Mode.
Figure 4-9 Access Control Board
According to the picture above, the RS-485 serial port corresponds to UART2 and UART3. RS-232
serial port is corresponded to UART7 and UART8. Wiring Interface is corresponded to UART1,
UART4, UART6, UART6, and Lane.
The access control board
descripons are as follows:
UART2/UART3 Jumper Cap
Reserved serial port. Use the jumper cap to switch the serial port
communicaon mode. You
can switch between the RS-485 communicaon mode and the RS-232 communicaon mode. By
default, it is in RS-485 communicaon mode.
UART6 Jumper Cap
Use the jumper cap to switch the serial port communicaon mode with the sub lane controller.
You can switch between the RS-232
communicaon mode and the RS-485 communicaon
mode. By default, it is in RS-232 communicaon mode.
