EM100-EV Evaluation Board<br />

The EM100-EV Evaluation Board offers a convenient way of testing<br />

EM100 <strong>Ethernet</strong> Module. The board features the following components:<br />

· A socket for EM100 Module installation<br />

· Power jack and a linear voltage regula<strong>to</strong>r circuitry (12VDC-->5VDC, adap<strong>to</strong>r<br />

current rating must be no less than 500mA)<br />

· RJ45 connec<strong>to</strong>r<br />

· DB9M RS232 connec<strong>to</strong>r and RS232 transceiver (supported signals are RX, TX,<br />

RTS, CTS)<br />

· Setup but<strong>to</strong>n (connected <strong>to</strong> the MD line of the EM100)<br />

· <strong>Ethernet</strong> LEDs and Status LEDs (connected <strong>to</strong> LED lines of the EM100)<br />

Power 2.2.1.1 Jack<br />

Power Jack of the EM100-EV accepts "large" power connec<strong>to</strong>rs with 5.5mm<br />

diameter. Use ARP-1014, ARP-1015A, or ARP-1018A power adap<strong>to</strong>r supplied by<br />

<strong>Tibbo</strong> or similar adap<strong>to</strong>r. Nominal voltage is 12VDC and adap<strong>to</strong>r current rating should<br />

be at least 500mA. On the power jack, the ground is "on the outside", as shown on<br />

the figure below.<br />
