Siemens Ruggedcom RMC30 2 Port Serial to Ethernet Servers


The RMC30 is a utility-grade, 2-port Serial-to-Ethernet server that has been specifically designed to operate in electrically harsh and climatically demanding environments. The RMC30 offers both an RS232 port and an RS485/422 port simultaneously via a solid screw down terminal block. The 10Base-T Ethernet port supports both auto-negotiation and auto crossover detection and simplifies cabling. Simple and intuitive network based configuration using either the built in Web or Telnet server makes setup a breeze.
