Should ONLY be used on 10FL series RUGGEDCOM RMC products.
The transparent mode can be utilized when BOTH the copper side and fiber side
devices are capable of auto-negotiating duplex mode and speed as per TIA/EIA-785.
When both partners are capable of negotiation, the RUGGEDCOM RMC can support
100Base-TX to 100Base-SX, full duplex and copper-to-fiber media conversion on
10FL standard electronics and fiber media. The TIA/EIA-785 standard allows for 10FL
communication lines that are less than 300m in length to be upgraded to 100 Mb/s
communication links.
The HDX and FDX modes exist to accommodate fiber link partners that are operating
in the forced mode. Due to the high number of forced full duplex fiber optical
devices available, the factory default is the FDX, full duplex, mode.
