1.10. Communication Port Wiring

The EKI-9316P / EKI-9312P are industrial Ethernet switches provide connections to
standard Ethernet devices. There are three types of communication ports the switches:
RJ45 Ethernet ports, fiber optic Ethernet ports, and a USB console port for
management options.

1.10.1 RJ45 Ethernet Cable Wiring

For RJ45 connectors, data-quality, twisted pair cabling (rated CAT5 or better) is recom-
mended. The connector bodies on the RJ45 Ethernet ports are metallic and connected
to the GND terminal. For best performance, use shielded cabling. Shielded cabling may
be used to provide further protection.

1.10.2 Mini-GBIC Fiber Transceivers

Up to four fiber optic ports are available (dependent on model) for use in the switch. Refer
to the technical specifications for details.
The Gigabit Ethernet ports on the switch are 100/1000BaseSFP Fiber ports, which
require using the 100M or 1G mini-GBIC fiber transceivers to work properly. Advantech
provides completed transceiver models for different distance requirement.
The concept behind the LC port and cable is quite straightforward. Suppose that you are
connecting devices I and II; contrary to electrical signals, optical signals do not require a
circuit in order to transmit data. Consequently, one of the optical lines is used to transmit
data from device I to device II, and the other optical line is used transmit data from device II
to device I, for full-duplex transmission.
