Patton EHA2172 User Manual

Patton’s EHA2172 breaks distance and speed barriers with up to 50 Mbps full-duplex and
distances of up to 5,500 feet (1,700m) over already existing infrastructure cabling.

EnviroNET™Model EHA2172

Ruggedized 50-Mbps Ethernet Extender

Extenders

The Model EHA2172 simplifies network
extension by utilizing twisted-pair infrastruc­ture previously used for legacy systems such
as serial circult TTL, RS-232 and RS­422/485, phone lines, or even alarm circuits
to be used for extending or connecting
Ethernet devices together. With a pair of
EHA2172s (or combined with a Patton 2172
or 2172R), a user can extend network con­nections up to 5,500 feet. Reusing already
existing infrastructure for Ethernet

Networking eliminates purchasing expensive

fiber and Cat5E or greater cabling. Most

important, it completely eliminates the has-

sle, expense, and downtime of cable installa-

tions. The EHA2172 operates in rugged envi-

ronments and is NEMA3 certified. The

EHA2172’s steel case can be conveniently

mounted on a wall or pole.

50 Mbps, Full-Duplex Operation
Over Twisted-Pair

Reduces the cost and hassles of new installa­tions. Utilizes installed voice-grade twisted pairs
to eliminate the expense of fiber or Cat5e cabling.

NEMA 3 Compliant, Ruggedized
Steel Enclosure

Protection against elements such as dirt, rain,
sleet, snow, dust, and that will be undamaged by
the external formation of ice on the enclosure.

Plug and Play

No configuration or cable hassles during instal­lation with auto-sensing 10/100, full or half
duplex, and auto MDI-X.

Extended Temperature 0 to 50ºC

Operates in environments that do not have
heating or cooling options.

Flexible installation

Wall or DIN rail mountable.

EnviroNET™EH Series

Environmentally Hardened

Built to NEMA 4 specs, the durable EH

Series protects against rain, sleet, snow,
dirt, dust, ice build-up, high humidity (moisture) and
physical tampering. Able to operate in temperatures
ranging from 32 to 122°F (0 to 50°C), it is ideal for use
in environments with controlled temperatures.

Typical Application

The Model EHA2172 auto-rate Ethernet Extenders are ideal for delivering net­work connections to remote offices and Ethernet enabled devices that are
beyond the 328-foot (100-meter) distance limit of Ethernet. The 50 Mbps
throughput eliminates bandwidth concerns previously experienced with other

copper wired transmission technologies. By utilizing existing voice grade cop­per pairs the expense and hassle of installing low capacitance or fiber cable is
no longer required.
