7 Ethernet Ports
7.1 Copper Ports
The DVS500 has an IEEE 802.3 Ethernet Interface for 1000Base-T, 100Base-TX, and 10Base-T applications
(802.3, 802.3u, and 802.3ab) conformance. The RJ45 Ethernet ports features auto negotiating, and auto-
crossover functions. The following figure shows the RJ45 port pins configuration.
7.2 Copper Gigabit Ethernet 1000Base-TX Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbits/s Ethernet communications over
distances of up to 100 meters using 4 pairs of category 5 (or higher) balanced unshielded twisted-pair
cabling. For wiring guidelines, system designers and integrators should refer to the Telecommunications
Industry Association (TIA) TIA/EIA-568-A wiring standard that characterizes minimum cabling performance
specifications required for proper Gigabit Ethernet operation. To ensure reliable, error-free data
communications, new and pre-existing communication paths should be verified for TIA/EIA-568-A
compliance.
In general the following recommendations should be followed for copper data in high electrical noise
environments:
• Data cable lengths should be as short as possible, ideally limited to 3m (10ft) in length. Copper
data cables should not be used for inter-building communications.
• Power and data cables should not be run in paraellel for long distances, and ideally should be
installed in separate conduits. Power and data cables intersect at 900 angles when necessary to
reduce inductive coupling.
• Shield/screened cabling can optionally be used. The cable shield should be grounded at one
single point to avoid the generation of ground loops.
