UPS remote monitoring connection mode 2 -- Serial port connection (RS-232/RS-485)
Uninterruptible power systems (UPS) are an essential part of modern information technology infrastructure, ensuring the continuous operation of critical equipment in the event of a power outage. In order to effectively manage and monitor the performance of the UPS, many devices are equipped with remote monitoring modules. In addition to the network connection method, serial port connection (such as RS-232 and RS-485) is also one of the common options for UPS remote monitoring. This section describes concepts related to serial port connection (RS-232/RS-485) of the UPS remote monitoring module.
Main content
Serial connection is the way of data transmission through serial communication protocol. RS-232 and RS-485 are two widely used serial communication standards, each with its own unique characteristics, suitable for different application environments.
RS-232
RS-232 is a common serial communication standard that transmits and receives data through a single signal line and a common ground line. Its features include:
Simplicity: The RS-232 communication protocol is relatively simple and easy to implement, which is suitable for short distance data transmission.
Moderate speed: Under normal circumstances, the transmission speed of RS-232 can reach 115200bps, which is suitable for most UPS monitoring needs.
Distance limitation: The effective transmission distance of RS-232 is usually within 15 meters, which is suitable for scenarios where devices are close.
RS-485
RS-485 is a more complex serial communication standard that allows multiple devices to communicate over the same differential signal line. Its features include:
Long-distance transmission: RS-485 can support transmission distances up to 1200 meters, which is suitable for applications requiring long-distance data transmission.
Multi-point communication: RS-485 allows up to 32 devices to communicate on the same network, making it suitable for large UPS systems.
Strong anti-interference ability: Due to the differential signal, RS-485 performs well in environments with more serious electrical interference, ensuring the stability of data transmission.
Advantages and application scenarios
