1000BASE-T Network
The 4G4202‐72 and 4G4282‐49 support 10/100/1000 Mbps by means of fixed RJ45 front
panel connectors. These connections support copper wire connections that can operate up
to 1000 Mbps. The device at the other end of the twisted pair segment must meet IEEE
802.3‐2002 network requirements for the devices to operate at Gigabit speed.
Note: The fixed ports of each module support Category 5 UTP cabling with an impedance
between 85 and 111 ohms for 100 and 1000 Mbps operation and can automatically sense
the port speed of the other device and adjusts its speed accordingly.
