NOTE: for Power Substations:
In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the M12 ports are intended for connectivity
to other communication equipment such as routers or telecommunication
multiplexers installed in close proximity (i.e., less than 2 meters or 6.5ft) to the
6KM. It is not recommended to use these ports in substation applications to
interface to field devices across distances which could produce high (greater than
2500V ) levels of ground potential rise (GPR) during line-to-ground fault
conditions. The 6KM passes the 1613 specifications for zero packet loss with fiber
ports & with M12 ports used as indicated here.

Connecting Twisted Pair for Gigabit (CAT5e or better, UTP or STP)
The M12 Gigabit ports of the Magnum 6KM can be connected to the media
types, 1000BASE-T or CAT 5E or better 100-ohm UTP or shielded twisted pair (STP)
balanced cable. The CAT 5E or better 100-ohm UTP or shielded twisted pair (STP)
balanced cable is recommended to use when making 1000BASE-TX connections. In
either case, the max distance for unshielded twisted pair cabling is 100 meters (328 ft).
The following procedure describes how to connect a 1000BASE-T twisted pair segment
to the M12 port. The procedure is the same for both unshielded and shielded twisted pair
cables.
1. 1000BASE-T connections require that all four pairs or wires be connected.
Using CAT5e or better twisted pair cable with M12, 8-pin connector at 6KM
side, insert the end of the cable with an M12 plug into the M12 connector of the
port.
(unshielded or shielded cables and wiring may be used)
2. Connect the other end of the cable to the corresponding device
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established.
