RD300-OF
Serial RS232/RS422/RS485 to multimode fiber optic media converter
Using fiber optic enables to use a higher communication bandwidth while offering a total immunity against EMI/RFI interferences and an increased security as well.
The optical fibre still offers other advantages: use without risk in an explosive environment, no EMC emission, no ground loops, immunity against lightning and high voltage environments, they are finally lighter, less cumbersome, inert and corrosion resistant ...
Why using fiber optic ?

Plug & Play
The RD300-OF device features a self configuration mechanism based on a CPLD component freed you from the tiresome operation which consist in the serial parameters setup, product is "Plug & Play".
Security
RD300-OF features in standard a built-in system to control the fiber integrity, it reports automatically any failure with an error LED and also setup a relay contact (MOSFET) to activate any external safety device.

Point to Point topology
This configuration enables to control a single equipment installed in a very polluted or distant area. The optical line is totally insensitive to EMI/RFI perturbations.
Simple ring topology
This topology enables to build a simple ring whereas the master equipment is installed in the middle.
