EISK5-GT
Plug and Play Gigabit Switching Hub for Automation Systems
Installation Guide
The EISK5-GT gigabit switching hub is designed for the automation environment. Like
all Ethernet switches from Contemporary Controls, it features non-blocking (full wire-
speed) operation. It divides an Ethernet network into five collision domains —
―bridging‖ data links to create larger network diameters than possible with repeating
hubs. Each port automatically negotiates its data rate to 10, 100 or 1000 Mbps —
controlling data flow with the PAUSE function in full-duplex links or with the
backpressure method in half-duplex links.
The switch provides preamble regeneration with symmetry and amplitude
compensation —retiming signals to eliminate jitter. Digital pre-emphasis compensates
for inherent signal strength roll-off. Link integrity is monitored, verifying that a working
adapter or hub is on the distant end of a segment.
Port assignments are learned by reading Ethernet frames and logging the source
addresses to a table. Throughput is improved by restricting traffic to those ports party
to a data exchange —while other data is simultaneously exchanged on other ports.
Store-and-forward operation is implemented and broadcast, multicast, or unicast
transmissions are received by all ports.
The EISK5-GT has five Auto-MDIX ports for attaching local devices. In addition to a
power LED, each port has LEDs showing link/activity/rate.
The EISK5-GT is powered from a low-voltage source and is provided with a writeable
label for easy identification of the remote device attached to each cable.

Power Options
Power Considerations
Voltage in the specified range must deliver current commensurate with power
consumption. The recommended size for solid power conductors is 16–22 AWG; for
stranded conductors, use 16–18 AWG. COM is directly connected to zero volts and the
chassis is isolated from zero volts. Input connections are reverse-polarity protected.
Network Connections
The switch employs Auto-MDIX technology so that either straight-through or crossover
cables can be used to connect to network interface adapters or to another hub.
LED Indicators
The ―PWR‖ LED glows solid green when the switch is properly powered. To aid in
troubleshooting, each port has two LEDs. The Port 1 LED labelled ―H‖ glows if a link
exists at 1000 Mbps (green) or at 100 Mbps (yellow). The LED labelled ―L‖ is normally
unlit but glows yellow if a 10 Mbps link exists. Either the ―H‖or ―L‖LEDs flash to show
activity. The LEDs of Ports 2–5 are unlabeled but work the same.
