Ethernet cables are divided into two categories: straight-through and crossover.
Straight-through cable: The sequences of the twisted pairs crimped in the RJ-45 connectors at both
ends are the same. It connects a terminal device (PC or router) to a HUB or LAN switch.
Crossover cable: The sequences of the twisted pairs crimped in the RJ-45 connectors at both ends
are different. It connects a terminal device (PC or router) to another terminal device. You make
crossover cables by yourself.
In making network cables, shielded cables are preferred for the sake of electromagnetic compatibility.

Connecting the Interface Cable

Follow these steps to connect the interface cable:
Step1 Plug one end of the cable to an Ethernet port of the FE module on the V100-E and another end to the
desired device. (For a PC or router, use a crossover cable; for a hub or LAN switch, use a
straight-through cable.)
Step2 Power up the V100-E and check state of the LINK LED on the FE module. ON means a link is present.
OFF means no link is present and you should check the connection.
Read the mark of a port carefully before you connect it; a wrong connection can cause damages to the
interface module and even the device.

1GBE/2GBE Module

Introduction

1GBE and 2GBE are 10/100/1000Base-T electrical interface (RJ-45) modules, where GBE stands for
Gigabit Ethernet. 1GBE provides one interface and 2GBE provides two interfaces. They are designed
for the communication between the V100-E and the LAN.
The GBE modules support:
The transmission distance of 100 meters (328 ft) over the category-5 twisted-pair cable.
The operating rates of 1000 Mbps, 100 Mbps and 10 Mbps, with autosensing.
