IMC-100C is a compact sized, industrial grade, non-managed, Fast Ethernet media converter that supports conversion between electrical 10/100Base-TX and optical 100Base-FX Ethernet. Simple DIP switch settings allow configuring UTP port for auto-negotiation or for forced 10/100 speed and half/ full duplex as well as for enabling LFPT (Link Fault Pass Through), and selecting Switch Mode (store & forward) or Converter Mode (Jumbo frame Pass-through). Housed in rugged DIN rail or wall mountable enclosures, these converters are designed for harsh environments, such as industrial networking and intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications. Industrial designed converters feature rugged design with metal housings or wall mounting for DIN Rail mounting, highly reliable electrical design to support very high MTBF (mean time between failure), enhanced safety and surge protection, better EMS (Electro Magnetic Susceptibility), as well as expanded operating temperature ranges. The IMC-100C Series media converters are available in two operating temperature ranges, a standard -10° to 60°C model range or an extended -40° to 75°C range. DC input Power 12/24/48VDC (9.6~58VDC) or 24VAC (18~36VAC) IP30 rugged metal housing, compact and fanless Wide operating temperature -40~75°C (IMC-100C-E ) UL508,CE,FCC,Rail traffic EN50121-4 Industry grade EMS certification, EMI, EN61000-6-2, EN61000-6-4 certified Store-and-Forward mode and Pass-through mode (set by DIP SW) Conversion between 10/100Base-T(X) and 100Base-FX cable interface Provide a 4 Pole DIP-Switch to set functions
