EISK5-100T/H
Skorpion Diagnostic Switch for Protocol Debugging
Installation Guide
The EISK5-100T/H is designed as an aid in diagnosing Ethernet communication
issues and debugging software. This device has all of the features of a normal
switch except that — like a repeating hub — it passes messages received by any port
to all other ports. This allows the activity of all ports to be monitored by a ―sniffer‖
attached to any port — an ability that would otherwise require the ―port mirror‖ function
of a more costly managed switch.
The five ports of the EISK5-100T/H offer features that traditional repeating hubs
do not. Each port supports Auto-MDIX — so either straight-through or crossover
cabling can be used. The collision domain is terminated at each port — so that a
network of EISK5-100T/H units has no cabling length limit — except that each
segment cannot exceed the 100 m specification for Ethernet. Store-and-forward
operation mitigates against lost messages. Each port automatically negotiates
its data rate to 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.
Link integrity is monitored — verifying that a working device is on the far end of a
segment. In addition to the unit's power LED, each port has two LEDs — one
showing link/activity/rate, and one showing duplex status.
The unit operates from low-voltage AC or DC power and is provided with a
writable label for easy identification of the remote device attached to each cable.

  • Page 3 Power Options Power Considerations Voltage within the specified range must deliver current that is commensurate with power consumption. The 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-polarity protected.
  • Page 4 Technical Support. Warranty Contemporary Controls (CC) warrants this product to the original purchaser for five years from the shipping date. If it fails to operate in compliance with its specification during this period, CC will, at its option, repair or replace the product at no charge.
