EIM EIM
Industrial Ethernet 10 Mbps Miniature Repeating Hub
The EIM4-10T miniature Industrial Ethernet repeating hub is a simple, cost-
effective method for increasing 10BASE-T node count or network distance.
It has four normal Ethernet ports for attaching local devices and one uplink
port for connecting two hubs without the need for a crossover cable.
Conforming to the IEEE 802.3 standard, the hub provides preamble
regeneration with symmetry and amplitude compensation. It retimes signals
so that jitter, introduced by transceivers and cabling, does not accumulate
over multiple segments. Upon detecting a runt packet or collision, the hub
generates a jam signal. Additionally, jabbering ports are automatically
partitioned so that the entire network is not disrupted.
The EIM4-10T adds digital pre-emphasis to transmissions, compensating
for the inherent signal strength roll-off of twisted-pair cable. Each twisted-
pair segment length can be up to 100 meters. Shielded RJ-45 connectors
accommodate either UTP or STP cabling. Link integrity is monitored,
confirming a working adapter or hub is on the other end of the segment.
Hubs can be cascaded with either straight-through or crossover cables.
Several LEDs aid in troubleshooting. There is one common Collision LED
and one LED to indicate power. Each port has one green LED which
indicates link established when solid and port activity when flashing.
The unit mounts on TS-32 or TS35 DIN-rail, can operate from a wide range
of low-voltage AC or DC power and offers redundant power connections.
Designed for Industrial Ethernet applications, the hub complies with EMC
immunity and emissions compatibility standards for industrial environments.
