leads are isolated from the Ethernet
signal leads to reduce EMI
and crosstalk.
-Signal routing is designed for NIC
applications. See datasheet
RJ3xx & RJ4xx-Schematic 4H1 for
Hub signal routing.
-Other signal routing is available. Please
contact the factory at the numbers listed
below.
-Standard LEDs are green. See note below
for options.
