outdoor environments, and under severe conditions such as water spray,
salt, and extreme fluctuations in cold and heat.
The Fluidmesh 4200 FIBER has successfully passed stringent
environmental certification tests, including the European Committee for
Standardization
(electronic equipment used on rolling stock for
railway applications) and
(fire protection on railway vehicles)
tests.
Examples of specific certification tests included:
• Verification of resistance to salt water intrusion and corrosion. This
consisted of subjecting the unit to running, high-pressure salt water
for 24 hours, followed by a 24-hour drying time. The unit was then
carefully examined to verify that no corrosion or water ingress were
found.
• Verification of resistance to fluctuating temperatures. This consisted
of placing the unit in a climatic chamber and subjecting it to
operating ranges between -40°C and 80°C, for four hours.

IMPORTANT
Always use outdoor-rated, RF-shielded Ethernet cables when
connecting the Power and LAN ports of a transceiver unit to
external hardware.

This section describes the terminal assignments for M12 A-coded
connectors equipped with five pins (power only) and with eight pins
(power and data).
