Introduction
The RUGGEDCOM RMC20 series of media converters are industrially hardened and specifically designed to operate
reliably in electrically harsh and climatically demanding environments.
The RUGGEDCOM RMC20 is a utility-grade, protocol-independent, serial-to-fiber and serial standards converter for
all your serial communication requirements. The RUGGEDCOM RMC20 allows RS485, RS422, or RS232 devices or
networks to communicate over secure, noise immune, optically isolated, fiber optic cabling at extended distances
as well convert RS232 to either RS485 or RS422 serial standards.
The RUGGEDCOM RMC20 was designed specifically to provide years of maintenance free operation for all your
mission-critical, real-time control applications. To provide the utmost in reliability, the RUGGEDCOM RMC20
is tested to the most stringent international EMI and environmental standards for use in HV/MV electric utility
substations and industrial manufacturing, process and control and intelligent transportation systems applications.
All RUGGEDCOM products are packaged with a high reliability, built-in power supply (24V, 48V or HI voltage
options) and enclosed in a rugged galvanized steel enclosure suitable for panel or DIN-rail mounting.
