Hexin TD-277S-MM RS-485/RS-422 to Multi-Mode Fiber Converter

Model: TD-277S-MM

Name: RS-485/RS-422 to Multi-Mode Fiber Converter 

Description

TD-277S-MM RS-485/RS-422 to Multi-Mode Fiber Converter is a professional design in order to solve the RS-485/RS-422 serial signals and multi-mode fiber optic signals for communication. RS-485/RS-422 to Multi-Mode Fiber Converter provide users transparent transmission from RS-485/RS-422 serial port to fiber port, the user need not change the existing software, can send the RS-485/RS-422 serial signals to long distance stability. TD-277S-MM RS-485/RS-422 to Multi-Mode Fiber Converter for use with methods of work in pairs, it would be more convenient to the user's RS-485/RS-422 serial signal through fiber optic transmission and then revert to the RS-485/RS-422 serial signal. In optical fiber is optical signal, there is no electrical conductivity, it will not be the impact of electromagnetic waves and the thunder and lightning, which has a strong anti-jamming capability. Particularly suitable for the work environment is harsh, distant outdoor occasions to use.

Feature

• Optical signals transparently convert RS-485/RS-422 signals without the need for jumper settings, automatically switching.
• Unique zero-delay auto-conversion transceiver technology and the baud rate adaptive technology.
