EM120/EM200-EV
The EM120/200-EV Evaluation Board offers a convenient way of testing the EM120
(which is no longer supported as a programmable device) and
modules. The board features the following components:
·
A socket for EM120 or EM200 installation
·
and a switching power regulator (12VDC-->5VDC, adaptor current
rating must be no less than 500mA)
·
and 10/100BaseT Ethernet Magnetics (EM120 and EM200 do not
have built-in magnetics)
·
and RS232 transceiver (supported signals are RX, TX,
RTS, CTS, DTR, DSR)
·
Setup button (connected to the
·
Two Ethernet LEDs and two status LEDs (connected to
of EM120/200).
Further information on status LEDs can be found in
.
·
Five additional LEDs connected to lines
·
provides access to EM120/EM200's serial and general-
purpose I/O pins (therefore, all I/O lines on this connector are of TTL type)
Power Jack
Power Jack of the EM120/EM200-EV accepts "large" power connectors with 5.5mm
diameter. Use
, or
Tibbo or similar adaptor with 12V nominal output voltage. Adaptor current rating
should be at least 500mA. On the power jack, the ground is "on the outside", as
shown on the figure below.
