Some problems encountered by USB to RS485 rs232 to rs485 converter


The USB to RS485 rs232 to rs485 converter manufacturer tells you that the 485 bus system is widely used in security protection, access control and attendance systems, and industrial automation systems. The manufacturer of USB to RS485 rs232 to rs485 converter tells you that in the 485 bus system, most of the final data of the system has to be finally transmitted to the computer, and the computer generally exchanges data with the 485 bus system through the RS232 serial port. So the 232 to 485 converter becomes the standard configuration of the 485 bus system.

The manufacturer of USB to RS485 rs232 to rs485 converter tells you that as the 485 system becomes larger and larger, more and more 485 devices are connected to the 485 bus, which leads to the deterioration of the stability of the 485 bus. The manufacturer of USB to RS485 rs232 to rs485 converter tells you that there are already converters on the market that can load 128, 256 or even 400 485 devices. Because the 485 bus uses a bus connection form, if there is a problem with a 485 device, it will cause the whole Phenomenon that there is a problem with the 485 bus. So in terms of the stability of the 485 bus, when the device reaches a certain number, it is recommended to use a 485 hub to ensure the stability of the 485 bus.
The manufacturer of USB to RS485 rs232 to rs485 converter tells you from the probabilistic analysis, assuming that the error-free time of 485 devices on the 485 bus is 99.9%, when there are 128 485 devices on a bus, the error-free time is 99.9% 128th power, the error-free time rate drops to 87.98%, and if you use a 4-port 485 hub to divide 128 485 devices into four 32 485 devices, the error-free time is 99.9% to the 32th power , Its error-free time is 96.85%, which greatly improves the stability of the 485 bus.
