2.3. ETHERNET CONNECTIONS

The 7700ACO2-HD can communicate with VistaLINK
®
via its own Ethernet
connection, or via the 7700FC.
The –SLKE version only communicates via the 7700FC, as the Ethernet port is
reserved for streaming video.
The 7700ACO2-HD can be configured using the VistaLINK
®
-C Configuration tool connected by Ethernet.
The 7700ACO2-HD is designed to be used with 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. The cable must be “straight
through” with a RJ-45 connector at each end. Make the network connection by plugging one end of the
cable into the RJ-45 receptacle of the 7700ACO2-HD and the other end into a port of the supporting hub.
The straight-through RJ-45 cable can be purchased or can be constructed using the pinout information in
Table 2-1. A colour code wiring table is provided in Table 2-1 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 2-1: 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.
The maximum cable run between the 7700ACO2-HD and the supporting hub is 300 ft (90 m). The
maximum combined cable run between any two end points (i.e. 7700ACO2-HD and PC/laptop via network
hub) is 675 feet (205 m). When you have connected the 7700ACO2-HD and set up the IP address you
should ‘ping’ the device from your PC to make sure that it is connected correctly.
