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.
Section 2.4
Using Straight Through or Crossover Copper
Wiring
To accommodate signals from end devices and network switching equipment, the RUGGEDCOM RMC is equipped
with an X-Over switch. This switch allows for the proper connection regardless of the cable type configuration.
