11. Setup and Configuration
You can use a PC to connect to the Tracker3 either the Windows configuration
program (otwincfg.exe) or a terminal emulation program of your choice, such as
HyperTerminal, PuTTY (available from http://www.putty.org), or Minicom.
To use the command console, connect at the proper baud rate (4800 baud is the
default) and press enter several times until you see a command prompt. When
using the USB port, the baud rate setting is ignored. To use the Windows
configuration program, simply start the program, select the COM port, and
power up the device.
The only setting absolutely required for normal APRS tracker operation is the
callsign. The defaults for all other settings should be reasonable, but you should
check on locally recommended settings, particularly for the digipeater path.
The USB port can be used for configuring the tracker with the otwincfg.exe
utility, accessing the command prompt, and connecting to a PC in KISS interface
mode.
11.1. USB Operation
When the USB connection is in use, the tracker draws its power from the host
system - no other connections are required for configuration of the unit.
Note that the Tracker3 does NOT act as a host device - the USB port is only used
for connecting to a PC, and cannot be used to connect a USB GPS receiver.
Windows systems require the provided .INF for the tracker to be recognized
properly. Once installed, you can find the COM port number assigned in Device
Manager. Alternatively, you can plug in the USB port after running otwincfg.exe
and the new port should be detected automatically.
Modern Linux distributions should automatically assign a device name like
/dev/ttyACM0 to the tracker. If the unit is not automatically recognized, you can
select the driver with the following command:
Mac OS X should assign a device name starting with /dev/cu.usbmodem.
