What is the difference between your 5800 series access control board and the 8900 series access control board? What is the difference in function?
Hello! Thanks for paying attention to our company's products! The control board of the 5800 series is standard, and the control board of the 8900 series integrates and upgrades the functions of the 5800 series R/T. The 5800 series are divided into R series and T series, the R series only supports RS485 communication, and the T series only supports TCP/IP communication. The 89 series supports RS485 and TCP/IP communication at the same time, and greatly expands the number of users and the data recorded in notes. The 5800 series has only one set of alarm relays, and the 8900 series has two groups. The 8900 series supports simultaneous online management of multiple computers, while the 5800 series supports only one computer management.
