2 Connect Development Kit to PC
In order to begin development work, the development kit needs to be connected to a host PC.
You can use either a serial cable (Section 2.1) or a USB mini-B cable (Section 2.2); both cables
are included in the development kit.
2.1 Connect Using Serial Cable
1. Connect the null-modem serial cable to the serial port connector on the baseboard and to an
empty COM port on your host PC. See Figure 2.1.
2. Connect the regulated 5V power supply to the appropriate power adapter for the location in
which you are using the development kit.
3. Plug the power adapter into an electrical outlet and the 5V line output connector into the
power-in connector on the baseboard. See Figure 2.1.
Figure 2.1: Connect Serial Cable
4. Before powering on your kit, you will have to install a terminal emulation program to
communicate with the development kit. Please proceed to Section 2.3 for details.
2.2 Connect Using USB Mini-B Cable
1. Connect the USB mini-B cable to the debug UART USB port on the baseboard and to an
empty USB port on your host PC. See Figure 2.2.
NOTE: The baseboard is equipped with an FTDI virtual COM port (VCP) chip that causes the
USB device to appear to your computer as an additional COM port. Settings for the terminal
emulation program will remain the same; however, a driver must be installed on your
computer for proper operation. A link to the driver and instructions for using the
USB-to-UART VCP chip can be found in Logic PD’s USB-to-UART VCP Chip Driver
ReadMe.2
2. Connect the regulated 5V power supply to the appropriate power adapter for the location in
which you are using the development kit.

3. Plug the power adapter into an electrical outlet and the 5V line output connector into the
power-in connector on the baseboard. See Figure 2.2.
Figure 2.2: Connect USB Mini-B Cable
4. Before powering on your kit, you will have to install a terminal emulation program to
communicate with the development kit. Please proceed to the next section for details.
2.3 Install Terminal Emulation Program
The Zoom DM3730 Torpedo Development Kit is designed to communicate with terminal
emulation programs using the included null-modem serial cable. The terminal emulation program
must support binary transfers in order to download software to the kit. Although Logic PD does
not support any particular terminal emulation program, we suggest using Tera Term for Windows
(Tera Term is not available for Linux users). Tera Term can be downloaded for free from
Logic PD’s website. To install Tera Term:
1. Download the ZIP file3from Logic PD’s website and extract the contents.
2. After extracting the contents, locate the teraterm-x.xx.exe file and double-click it.
3. Follow the on-screen instructions to install Tera Term.
2.3.1 Setup Tera Term
All Tera Term settings are controlled by an .ini file that you can modify as needed to make your
time in Tera Term as efficient as possible (for example you can preset the port settings).
1. Start the Tera Term program.
2. From the menu, select Setup > Serial port.
3. Select the appropriate COM port for your workstation and then change the port settings to:
a. Baud rate: 115200
b. Data: 8 bit
c. Parity: None
d. Stop: 1 bit
e. Flow control: None

4. Click OK.
2.4 Boot into LogicLoader
LogicLoader is a bootloader program created by Logic PD that provides the capability for loading
operating systems (OS) and applications. In addition, it provides a full suite of commands for
interfacing to the System on Module (SOM). These commands load OSs, configure hardware
platforms, bring up hardware, customize applications, perform tests, and manage in-field devices.
1. Make sure the development kit is set up as described in Section 2.1 or Section 2.2.
2. Remove the pre-built OS image SD card from the baseboard, if one is inserted. This step is
important because LogicLoader boots from onboard flash.
3. Start the terminal emulation program on your host PC.
4. Verify that the serial port settings are correct (see Figure 2.3 in the previous section).
5. Move the power switch to the ON position to boot the development kit.

6. In your host PC’s terminal emulation program, you should see a LogicLoader screen similar
to that below (version numbers and other details may differ from what is shown).

7. You are now ready to work with the DM3730 Torpedo SOM or the
DM3730 Torpedo + Wireless SOM using LogicLoader. For more information on LogicLoader
and its capabilities, please see the LogicLoader documentation provided by Logic PD. These
documents are available on Logic PD’s website and their download locations are referenced
in Appendix A of this document.
