How to increase the data transfer distance over Ethernet cable between two RS-232 devices?

RS-232 interface provides the data exchange between two devices on a distance of up to 15 meters. To overcome this limit, MOXA offers two solutions: RS-232/422/485 to Ethernet converters or RS-232 to RS-422/485 converters.

1. Using NPort serial interface server

“Transparent” extension of serial communication line of RS-232/422/485 under Ethernet technology. Data transmission is possible not only in accordance with “point-to-point” topology, but also over a local network or Internet network.

RS-232 device ----NPort----LAN----NPort----RS-232 device

In NPort devices, Pair Connection mode allows transparent transmission of serial data over Ethernet networks.

See the serial interfaces assortment in the catalog.

1. Using RS-232 to RS-422/485 converter

One converter converts RS-232 to RS-485, then the second one converts RS-485 back to RS-232.
