Product details
Model Number: NT-277S-20
Brand Name: N-net
Key Specifications/Special Features:
OverviewNT277 is a type of RS232/RS485/RS422 serial port fiber optic modemIt adopts industrial standard design and its wall type outface design supports DINrail standard lead rail installation, featuring easy installationPresently many users make use of RS232/RS485/RS422 serial port fiber optic modem to solve the electro magnetic interference in engineers and to extend the RS232/RS485/RS422 serial port transmission distance to several or even tens of kilometersNT277 can provide users with RS232/RS485/RS422 serial port 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 thundersKey features
