FEATURES
Power and signal isolated RS-485/RS422 transceiver
Convenient connections for power and signal through screw
Configurable as half-duplex or full-duplex
5 V or 3.3 V operation
Easily configurable through jumper connections
Test points for measuring all signals
Layout optimized for emissions according to the AN-0971
GENERAL DESCRIPTION
The
easy evaluation of the ADM2582E and ADM2587E power and
signal isolated RS-485 transceivers. Screw terminal blocks give
convenient connections for the power and signal connections.
See the last page for an important warning and disclaimers.
Passes the EN55022(2001) Class B emissions standard
terminal blocks

evaluation board can be used for
Evaluating the ADM2582E/ADM2587E
EVALUATION BOARD
Rev. 0 | Page 1 of 8
Figure 1.
The board can be easily configured by jumper connections.
The board is configurable as half-duplex or full-duplex and
has a 120 Ω termination resistor fitted on the receiver input.
The evaluation board can be used with both the ADM2582E
16 Mbps part and the ADM2587E 500 kbps part. The driver
and receiver can be enabled and disabled by jumper connections.
Test points are included on the power and signal lines on both
sides of the isolation barrier.
RADIATED EMISSIONS
The ADM2582E/ADM2587E evaluation board is designed to
reduce emissions generated by the high frequency switching
elements used by the isoPower technology to transfer power
through its transformer. Guidelines mentioned in the
Application Note
of the evaluation board were measured by an independent test
facility and passed the EN55022(2001) Class B emissions standard.
