ETHERNET CONNECTIONS
Static or side panel content can be uploaded to the card’s internal compact flash using this port. All
7812UDXD series modules are designed to use either 10Base-T (10 Mbps) or 100Base-TX (100 Mbps)
also known as
Fast Ethernet
, twisted pair Ethernet cabling systems. When connecting for 10Base-T
systems, category 3, 4, or 5 UTP cable as well as EIA/TIA – 568-100
Ω
STP cable may be used. When
connecting for 100Base-TX systems, category 5 UTP cable is required. Make the network connection by
plugging one end of a “straight through” cable into the RJ-45 receptacle of the 7812 modules and the
other end into a port of the supporting hub. If you are connecting the 7812UDXD series module directly to
an Ethernet port on a computer you will have to use a “crossover” cable.
Straight-through RJ-45 cables can be purchased or can be constructed using the pinout information in
Table 3-1. A colour code wiring table is provided in Figure 3-5 for the current RJ-45 standards (AT&T
258A or EIA/TIA 258B colour coding shown). Also, refer to the notes following the table for additional
wiring guide information.

Figure 3-3: Colour Code Wiring for the Current RJ 45 Standards
Note the following cabling information for this wiring guide:
•
Only two pairs of wires are used in the 8-pin RJ 45 connector to carry Ethernet signals.
•
Even though pins 4, 5, 7 and 8 are not used, it is mandatory that they be present in the cable.
•
10BaseT and 100BaseT use the same pins; a crossover cable made for one will work with the
other.
•
Pairs may be solid colours and not have a stripe.
•
Category 5 cables must use Category 5 rated connectors.
The maximum cable run between the 7812UDXD series modules and the supporting hub is 300 ft (90 m).
Note that the two LEDs on the Ethernet connector are not used and will not light up when connected to an
Ethernet network. Ethernet functionality is not impacted by the lack of these LEDs lighting up.
