GENERAL DESCRIPTION
The eIMR Evaluation Kit is an evaluation platform for
the Am79C984A enhanced Integrated Multiport Re-
peater (eIMR). The evaluation board functions as a
standalone 10BASE-T unmanaged repeater. Four
10BASE-T ports and one AUI port are provided. The
compact size of the board indicates that an eIMR-
based design can be constructed inexpensively. Com-
plete schematics and layout information are included in
the kit.
The eIMR board provides a full set of LEDs, without the
need for external drivers. A set of LEDs are used for the
activity indication, used to display network traf鏗乧 activ-
ity. Each port also accesses 2 LEDs, each of which can
be con鏗乬ured to display Carrier Sense, Collision, Link,
Jabber or Partition Status. Two global LEDs display glo-
bal events. Six different LED schemes are supported.
The eIMR board is powered by a 12 V DC power supply
(included). An onboard regulator derives 5 V for the
eIMR board.
Included in the kit is a document describing the results
from a FCC Class B test. The eIMR board was tested
without using an enclosure, and passed successfully.
With an appropriately shielded enclosure, a design
using eIMR should meet FCC Class B with relative ease.
