B.2 Using the DTM-3237B Development Kit
B.2.1 Hardware Installation
The DTM-3237B board has to be connected with the USB cable to a development PC. Connect the
DTM-3237B to the power-supply using the power connector. The DTM-3237B will boot which will take
a few seconds. During this time the LEDs on the DTM-3237B are flashing in a start-up pattern. Wait
until the DTM-3237B status LED turns (blinking) green.
B.2.2 Debugger
Dtm3237BUtil is a GUI tool to view status, control settings and upload firmware to the DTM-3237B.
This utility can be found on the DekTec USB flash drive. It can also be downloaded from the DekTec
website. Dtm3237BUtil is an executable that can be run from any directory on your PC.
When started, the debugger enumerates serial ports and lets the user select the serial port to which
the DTM-3237B is connected. When a valid serial port is selected, all registers are read from the DTM-
3237B and shown in the GUI. Blue fields can be edited. These fields are written to the DTM-3237B
when the pen symbol to the right of the edit fields is clicked. Yellow fields are read only; they are read
when the refresh arrow is clicked.
