EICP Series
Industrial Ethernet 10/100 Mbps Compact Switching Hubs
Installation Guide
EICP Switches provide popular PnP functionality: auto-negotiation, 10/100 Mbps data
rate, half- or full-duplex operation, and flow control.
Each switch learns port assignments by reading Ethernet frames and logs source
addresses on a table which can hold over 4000 addresses. With this information, it
improves throughput by restricting traffic to only 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 EICP also 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.
All ports support PAUSE flow control for full-duplex links and backpressure for half-
duplex. All RJ-45 ports feature Auto-MDIX for ease of cabling.
The switches are powered from wide-range, low-voltage AC or DC sources and
redundant power connections are provided for backup considerations. They come
with the hardware for either DIN-rail or panel mounting. The front panels feature a
power LED and bi-colour LEDs for the link status, activity, and data rate of each port.
Designed for Industrial Ethernet applications, each switch
complies with EMC immunity and emissions compatibility
standards for industrial environments.
