OpenTracker Series (OT1/OT1x/OT1m)

Firmware

The easiest way to update the firmware is to Load Firmware from Web using the otwincfg.exe program, as it will download the latest firmware and write it directly to the tracker. For otwincfg connection problems, see the FAQ.

The following firmware files are provided for off-line use. This firmware is for the OT1 series of OpenTrackers, and works with all revisions of the OpenTracker, OpenTracker 1x, and OpenTracker 1m trackers. It does not work with the OpenTracker+ or Tracker2 trackers.

OpenTracker Revision History

All circuit boards have the revision number printed on the board, usually in the lower right corner. The OpenTracker optionally came a translucent case, with several color choices, and was the only series to use a colored case.
  • Revision 1: This revision only had a few trackers (20-25) produced, and they did not have voltage measurement capability.
  • Revision 2: This revision had three variations, all marked "Rev 2". They differed only in the board manufacturer and some minor trace routing changes. Green circuit board.
  • Revision 3: This revision added a TTL-level carrier detect input, and featured an improved PCB layout. Black circuit board.
  • Revision 4: This revision replaced the 2N3904 transistors with 2N7000 FETs. A larger voltage regular was used, with a five volt output capability to power a GPS. Red circuit board.

OpenTracker 1x (OT1x)

OpenTracker 1xThe OT1x was the second APRS tracker produced, and it featured an extended circuit board that was designed to fit the PacTec CNS-0101 case. The case is opaque with a hole drilled for the LED. This product was replaced by the OpenTracker+, due to the discontinuation of key components.

OpenTracker 1x Revision History

Three revisions were made of the OT1x, and all used the same manual. All circuit boards had the revision number printed on the board. The revisions were primarily mechanical changes and a couple of parts substitutions.

Compared to the OT1, the OT1x had the following improvements:

  • Larger voltage regulator.
  • Output voltage selected with a jumper.
  • PTT keying method and audio level selectable through jumpers.
  • 1-wire data bus signal accessible on the serial connector for connection to the 1-Wire Weather station.

OpenTracker 1m (OT1m)

OpenTracker 1mThe OT1m was the third OpenTracker hardware variation produced. It added a 2.1mm power jack, RJ-11 accessory jack for 1-wire devices, and an optional 9 or 20 amp high-side switch to control power to a radio, particularly useful for solar powered weather stations. It was designed to fit a custom metal case.
