Updating Pieps Avalanche Transceivers

Pieps DSP Sport
Pieps DSP Sport

The Pieps DSP was the first avalanche transceiver to support updates. Now most avalanche transceivers support updates. The Pieps DSPs are updated via the earphone jack. (Learn how to update other transceivers).

You can send your transceiver to a Pieps Service Center and pay approximately $20us to have it updated. In 2013 Black Diamond announced that they would be selling a special cable (for $44.95us) which would allow you to install updates, perform diagnostics, and control other options, but more than a year later this cable is still not available. In any case, user-updatable firmware is a great concept and worth the wait.

DSP Sport and DSP Pro

The version number of the DSP Sport and DSP Pro software is displayed immediately after turning the device on.

Version Enhancements
Fall 2014

There are reliable rumors that Pieps will release version 2.0 in November 2014, but no hints as to what it will contain. The upgrade will need to be done at an authorized service center.

Version 1.5
February 2014

This version prevents a potential problem where the DSP Sport and DSP Pro might not receive a second transceiver's signal after marking a first transmitter in a very specific scenario. It also improved support for the Pieps TX600 (dog) transmitter.

Fall 2013

Initial release. (In the first few weeks following the release of the Sport and Pro, some units were shipped with a version 1.3 where the new features had not been fully tested. We'll have to see if Pieps chooses to jump to version 1.4 for the next release. UPDATE: The next release was version 1.5.)

Original (yellow) DSP and DSP Tour

To display the software version number on the yellow DSP and the DSP Tour models, press and hold the "(((" or "?" button and turn on your transceiver. The final version for these transceivers is version 8.2. Pieps does not plan to release any additional updates for these now-discontinued transceivers.

Fall 2011, version 8.2

Version 8.2 adds the ability for the DSP to search for a Pieps TX600 transmitter. (The TX600 is frequently attached to dogs or equipment.) You can read a brief summary of the new features in this press release. This is the final release for the original (yellow) DSP and DSP Tour.

Fall 2008, version 6.2

Version 6.2 includes all of the previous enhancements, plus enhancements dealing with the iProbe.

July 2007, version 5.0

Version 5.0 includes the Smart Transmitter, iProbe support, an "old beacon mode" (where the little men blink if a continuous carrier is detected), improved Mark and Scan functions, and an improved self-test. You can read a brief summary of the new features in this press release.

December 2006, version 4.0

Version 4.0 includes a new feature called a Smart Transmitter. Here is a brief explanation of this feature. (This feature is not in the DSP Sport and DSP Pro.)

Consider two cars at an intersection with their turn signals on. If the cadence of the turn signals is not identical, there will be times when the lights of both cars are blinking at the same time, periods when they are partially overlapping, and periods when the lights are blinking independently. This also happens with two transceivers. There are times when both transceivers are transmitting a "beep" at the same time ("signal overlap"), times when they are partially overlapping, and times when the beeps do not overlap. Unfortunately, when the beeps overlap, the searching transceiver treats this as one beep. This makes it difficult for the searching beacon to distinguish between multiple victims.

With the Smart Transmitter feature of the Pieps DSP, the DSP continually scans for a second transmitter while it is transmitting (i.e., it is receiving and transmitting at the same time). If it receives a signal from another transmitter (as happens during a multiple burial, but also while standing next to your buddy), the DSP will adjust the cadence of its "beep" so it isn't overlapped by the other beacon's "beep." I have tested this feature several times and it works well (it takes one to two minutes for the DSP to analyze the other beacon and adjust its cadence). The Smart Transmitter feature works when there is only one other beacon transmitting and that beacon is relatively close (approximately 5 meters). Beginning with the DSP Sport and DSP Pro, this feature is only active when the transceiver is relatively motionless (i.e., buried) to conserve battery power.

Some people have expressed concerns that the DSP's changing cadence will confuse the searching transceiver. I expect that the "confusion" caused by the DSP's changing cadence (which only happens once and occurs within two minutes) is less significant than the confusion caused by signal overlap issues.

You can read this very technical paper regarding the overlapping of signals during multiple burials or this abbreviated report.

December 2006, version 3.1

This version includes a handy frequency tester that allows you to test the frequency of your friend's beacon. The image to the right shows a Pieps DSP checking the frequency of a Tracker DTS. Learn more about the Pieps frequency tester here.

Version 3.1 also improves the Mark function which is used during multiple burials.

2005-2006 Season, version 2.8

Version 2.8 was released during the 2005-2006 season. This version dramatically improves the DSP's ability to locate out-of-frequency transmitters (i.e., older analog transceivers). It flashes "500" if the transmitting beacon is out-of-frequency. Learn more here. Big Brands Sale
