The EM120/200-EV Evaluation Board offers a convenient way of testing the EM120 (which is no longer supported as a programmable device) and EM200  embedded modules. The board features the following components:

  • A socket for EM120 or EM200 installation
  • Power jack and a switching power regulator (12VDC-->5VDC, adapter current rating must be no less than 500mA)
  • RJ45 connector and 10/100BaseT Ethernet Magnetics (EM120 and EM200 do not have built-in magnetics)
  • Setup button (connected to the MD line of EM120/EM200)
  • Two Ethernet LEDs and two status LEDs (connected to LED lines of EM120/200). Further information on status LEDs can be found in Status LEDs.
  • Five additional LEDs connected to lines P0, P1, P6-8 of 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)
