Ethernet Port
The IC-3121 provides a Gigabit Ethernet port. The Ethernet port provides a connection
between the IC-3121, a network, and other Ethernet devices. The IC-3121 automatically
detects the speed of the connection and configures itself accordingly.
A CAT 5e or CAT 6 1000Base-T Ethernet cable is required to achieve 1,000 Mbps (Gigabit)
Ethernet performance. CAT 5 Ethernet cables are not guaranteed to meet the necessary
requirements. While CAT 5 cables may appear to work at 1,000 Mbps, CAT 5 cables can cause
bit errors, resulting in degraded or unreliable network performance.
(Windows only) The network Ethernet port provides Wake-on-LAN functionality from the
power off state when associated with the Intel
®
driver. Wake-on-LAN must be enabled in the
Power Management tab of the Intel I210 Gigabit Network Connection Properties dialog for the
primary Ethernet port in Device Manager. The NI GigE Vision driver (NI-GEV) does not
support Wake-on-LAN.
