Product Details

Model Number: NT-277-M-#2796 Brand Name: N-NET Key Specifications/Special Features: Overview:NT-277 is a type of RS-232/RS-485/RS-422 serial port fiber optic modemIt adopts industrial standard design and its wall type outface design supports DIN-rail standard lead rail installation, featuring easy installationPresently many users make use of RS-232/RS-485/RS-422 serial port fiber optic modem to solve the electromagnetic interference in engineers and to extend the RS-232/RS-485/RS-422 serial port transmission distance to several or even tens of kilometersNT-277 can provide users with RS-232/RS-485/RS-422 serial port end-to-end transparent transmissionSince signals are transmitted over fibers and these optical signals are free of electrical conductivity, they have strong anti-interference capacity and are immune to high-voltage power or thundersFeatures:
