15 6641-22310
Ethernet TX
Electrical specification
IEEE std 802.3. 2005 Edition
Data rate 10 Mbit/s, 100 Mbit/s, 1000 Mbit/s, manual or auto
Duplex Full or half, manual or auto
Circuit type TNV-1
Transmission range Up to 150 m with CAT5e cable or better*
Isolation to All other
Connection RJ-45 auto MDI/MDI-X
Shielded cable Not required, except when installed in Railway applications as
signalling and telecommunications apparatus and located close
to rails*
Conductive housing Yes
Number of ports 3
* NOTE! Railway installation close to the rails.
To minimise the risk of interference, a shielded cable is recommended when the cable is located
inside 3 m boundary to the rails and connected to this port.
The cable shield should be properly connected (360°) to an earthing point within 1 m from this
port. This earthing point should have a low impedance connection to the conductive enclosure of
the apparatus cabinet, or similar, where the unit is built-in. This conductive enclosure should be
connected to the earthing system of an installation and may be directly connected to the protective
earth. Refer also to "Safety" section.
