5.3 Connecting Ethernet cables
Ethernet cable is used to connect the ISCOM6820-GP device with other devices, providing 10
Mbit/s, 100 Mbit/s, or 1000 Mbit/s transmission rate. According to the wiring corresponding
to the two ends of the RJ45 connector, the network cable can be divided into straight-through
cable and cross-over cable:
Straight-through cable: the wiring of twisted pair on both ends of RJ45 connectors
complies with EIA/TIA 568 B standard. Straight-through cables are used for connecting
devices with routers or PCs.
Crossover cable: one end of RJ45 connectors is EIA/TIA 568 A standard wiring, the
other end is EIA/TIA 568 B standard wiring. Cross-over cable is mainly used for directly
connecting devices with switches or hubs.
Connect the Ethernet cable according to the following steps:
Step 1 Select a proper cable according to the cable routing and make an Ethernet cable.
Step 2 Connect one end of the RJ45 connector of the Ethernet cable to the Ethernet port of the local
device, as shown in Figure 5-4.
