The serial fiber modem is a communication product for RS-232/422/485 serial port data to transmit data through optical fiber media. 485 interface. So, what are the device structure and main features of the serial optical modem?
Serial optical fiber modem structure
The serial optical modem is a communication product for RS-232/422/485 serial port data to transmit data through optical fiber media. The serial port light cat has a metal iron shell, which is sturdy and durable. It can realize panel installation, industrial rail installation, wall-mounted installation and other installation methods. The optical fiber interface adopts dual SC, FC, ST, etc. (FIBER-TX, FIBER-RX) interfaces, and the physical interface of the serial port is in the form of 12-hole binding posts. At the same time provide RS-232/422/485 interface. It can realize long-distance transmission of RS-232/422/485 serial data through optical fiber, which can effectively extend the transmission distance of serial communication signals.
Main features of serial optical fiber modem
The serial optical fiber modem overcomes the shortcomings of short distance and poor anti-interference ability of traditional serial communication, and also solves the problems of electromagnetic interference, ground ring interference, lightning strike and surge, which greatly improves the reliability and safety of data communication. sex and confidentiality. The serial optical fiber modem provides RS-232, RS-422 and RS-485 interfaces at the same time. RS-485 adopts advanced automatic flow control technology, which can automatically identify the signal flow direction. The serial port adapts to RS-232, RS-422 and RS- 485 interface, no external working mode selection switch, it is simpler and more convenient to use, and provides two forms of power interface, terminal type and socket type, which can be connected in actual use, and provide power supply and signal direction (← and →) Three indicator lights are convenient for users to check the communication status.
