Product Description

MWE485-HUB4 achieves the conversion of 1 port RS-232/485/422 to 4 ways RS-232/RS-485/422 in high rate with full optic-isolation at both full-duplex or half-duplex models. It supports to long distance communications above 2km and multi-drops (4×128 nodes). This HUB can be used for RS-232/485 conversion or extending the communication ability for RS-485 Bus.

Features and Benefits

-The signals at both ends are kept optically isolated;

-The master node and the slave node, and the slave node and the slave node are separately optically isolated;

-Comprehensive fault-tolerant mechanism, all the way from the node damage does not affect the communication of other nodes;

-Support (128×4) node polling network structure;

-Automatic identification of RS-485 signal flow direction, automatic forwarding with zero delay;

-Built-in intelligent module, automatic identification of RS-485 signal flow direction, automatic forwarding with zero delay;

-Industrial-grade design, optimized imported components, all surface mount technology.
