2.7. CONNECTING TO AN ETHERNET NETWORK
The 570DSK-12G-F is designed to be used with either a 1Gbe or 10Gbe network, also known as
Fast
Ethernet
, twisted pair Ethernet cabling systems. The cable must be “straight through” with a RJ-45
connector at each end. Create a network connection by plugging one end of the cable into the RJ-45
receptacle of the 570DSK and the other end into a port of the supporting network device.
The straight-through RJ-45 cable can be purchased or can be constructed using the pinout information
in Table 2-1. A color code wiring table is provided in Table 2-1 for the current RJ 45 standards (AT&T
258A or EIA/TIA 258B color coding shown). Also refer to the notes following the table for additional wiring
guide information.

Table 2-1 : Standard RJ45 Wiring Color 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 colors and not have a stripe.
• Category 5 cable must use Category 5 rated connectors.
The maximum cable run between the downstream Keyer and the supporting hub is 300 ft (90 m). The
maximum combined cable run between any two end points (i.e. downstream Keyer and PC/laptop via
network hub) is 675 feet (205 m).
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. The downstream Keyer rear panel is fitted with two LEDs to
monitor the Ethernet connection.
10/100: This LED is ON when a 100Base-TX link is last detected. The LED is OFF when a 10Base-
T link is last detected. 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 570DSK has established a valid linkage
to its hub, and it determines whether the 570DSK is sending or receiving data. This LED will be ON when
the 570DSK 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 570DSK is sending or receiving data. The LED
will be OFF if there is no valid connection.
