EISK8-100T
Plug and Play Switching Hub for Automation Systems
Installation Guide
The EISK8-100T Skorpion-8 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 eight collision domains —
―bridging‖ data links to create larger network diameters than possible with repeating
hubs. Each port automatically negotiates its data rate to either 10 Mbps or 100 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 EISK8-100T has eight Auto-MDIX ports for attaching local devices. In addition to
a power LED, each port has one LED showing link/activity/rate and one showing
duplex status.
The unit operates from a wide range of low-voltage AC or DC power.
The EISK8-100T is provided with a writeable label for easy identification of the remote
device attached to each cable.

Power Options
Power Considerations
Voltage in the range of 10–36 VDC or 24 VAC must deliver current commensurate with
power consumption. Recommended size for solid power conductors is 16–22 AWG; for
stranded conductors, use 16–18 AWG. Ground is directly connected to zero volts and
the chassis is isolated from zero volts. Input connections are reverse-polarityprotected.
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 2 LED labelled ―L‖ glows solid if a
link exists, flashes to show activity and shows data rate by colour: green for 100 Mbps
and yellow for 10 Mbps. The LED labelled ―D‖ glows solid green if full-duplex is on or
is unlit when that port is operating in half-duplex mode —but in half-duplex operation it
will flash if a collision occurs. The other port LEDs are unlabeled but work the same.
