EISK16-100T
Plug and Play Switching Hub for Industrial Automation Systems
Installation Guide
The EISK16-100T
Skorpion-16
switching hub is designed for the Industrial Automation
environment. Like all Ethernet switches from Contemporary Controls, it features non-
blocking (full wire-speed) operation. It divides an Ethernet network into 16 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 EISK16-100T has 16 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 EISK16-100T is provided with a writable label for easy
identification of the remote device attached to each cable.
