EM120/EM200-EV Evaluation Board


The EM120/200-EV Evaluation Board offers a convenient way of testing EM120 and EM200 Ethernet Modules. The board features the following components:

A socket for EM120 or EM200 installation
Power jack and a switching power regulator (12VDC-->5VDC, adaptor current rating must be no less than 500mA)
RJ45 connector and 10/100BaseT Ethernet Magnetics (EM120 and EM200 do not have built-in magnetics)
DB9M RS232 connector and RS232 transceiver (supported signals are RX, TX, RTS, CTS, DTR, DSR)
Setup button (connected to the MD line of EM120/EM200)
Two Ethernet LEDs and two status LEDs (connected to LED lines of EM120/200)
Five additional LEDs connected to lines  P0, P1, P6-8of the EM120/EM200
15-pin expansion connector 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)
