2.2. CONNECTING TO AN ETHERNET NETWORK
The HD201x is designed for use with 10Base-T (10 Mbps), 100Base-TX (100 Mbps) Ethernet cabling
systems. A single 10/100 Ethernet port is available on the HD0201x rear panel “Straight-Through”
Ethernet cables may be used when connecting to the HD201x.
Straight-through RJ-45 cable can be purchased or can be constructed using the pinout information in
Table 2-7. A colour coded wiring table is provided in Table 2-7 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.

Table 2-7: Standard RJ45 Wiring Colour Codes
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 also work with
the other.
•
Pairs may be solid colours and not have a stripe.
•
Category 5 cable must use Category 5 rated connectors.
Devices on the Ethernet network continually monitor the receive data path for activity as a means of
checking that the link is working correctly. When the network is idle, the devices also send a link test
signal to one another to verify link integrity.
10/100:
This Amber LED is ON when a 100Base-TX link is last detected. The LED is
OFF when a 10Base-T link is last detected (the LINK LED is ON). Upon power-
up the LED is OFF as the last detected rate is not known and therefore defaults
to the 10Base-T state until rate detection is completed.
LN/ACT:
This dual purpose Green LED indicates that the HD201x has established a valid
linkage to its hub, and whether the HD2014 is sending or receiving data. This
LED will be ON when the HD201x has established a good link to its supporting
hub. This gives you a good indication that the segment is wired correctly. The
LED will BLINK when the HD201x is sending or receiving data. The LED will be
OFF if there is no valid connection.
The HD201x has a specific IP address that may be set through the engineering front panel.
