S iia 18 NMIN 0803 H3 User Manual 4 1 GETTING STARTED Thank you for buying the NMIN 0803 H3 We hope you will find the NMIN 0803 H3 to be the incredibly useful controller board we intended it to be and easy to use as possible Figure 1 NMIN 0803 H3 Let s skip the features and get right to the operation Once we ve got communications then we can make some lights blink and know for sure that we re in business Let s make this H3 board talk to us We ll need PC running a terminal program Then we ll need a serial cable to connect from the PC to the NMIN 0803 H3 which hopefully you ve already gotten from us Then we need power such as from a 9V or 12VDC 300mA or higher wall transformer which hopefully you ve already gotten from us If we have those connections correct we will be able to talk to the NMIN 0803 H3 interactively The wall transformer can supply the power to the NMIN 0803 H3 board but do not connect it to the board yet The board can be seen in the figure below showing the connections of PJ1 power jack Connect the serial cable between the DB9 connector and the PC NMIN 0803 H3 User Manual 5 Power jack AC or DC DB9 for J serial pil Motor Reset LEDs ERR Motors BET Figure 2 Power and Serial Connections Once you have your serial cable and connectors and wall transformer and connectors ready follow these steps Start with the PC Install 1f not already instal
