TinyTrak4 Serial Splitter and Null Modem Adapter
This adapter will split the 2 serial ports available on TinyTrak4 J2 to two separate DB-9 connectors.
The computer side in the primary port, contains a null modem adapter and will plug directly to a computer serial port.
The GPS side is the secondary port, will plug directly to a GPS serial DB-9 plug, and carries the GPS power on pin 4.
This cable can also be used to update the TinyTrak4 firmware, and connect with the Configuration software. With it, the above null modem adapter/cable is not needed.
Note: Only the TinyTrak4 Alpha firmware supports the second serial port at this time. Other firmware does not.
TinyTrak4 Serial Splitter - $15.
TT USB Cable
This USB cable will connect a TinyTrak3Plus or TinyTrak4 to a computer USB port for configuring.
In addition, if the TinyTrak is set for 5V on J7 (TT3+) or JP6 (TT4) to power a GPS2, this cable will also power the TinyTrak from the computer.
It is a USB A to DB-9 female, and is basically a USB to serial adapter plus a F-F null modem cable,
with the bonus of providing 5V to power the TinyTrak via pin 4.
Note: since the TT USB provides power to the TinyTrak, the TinyTrak should NOT be connected to 12V when using the TT USB!
Drivers can be found HERE.
TT USB Cable - $20.
