ETHERNET CONNECTIONS

All 7814 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 – 568-100Ω 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 7814 modules and the other end into
a port of the supporting hub. If you are connecting the 7814 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 pin out information in
Table 2-1. A colour code-wiring table is provided in Figure 2-4 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.

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 7814 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.
