You can send your transceiver to a
Center and pay approximately $20us to have it updated, or you
can purchase a special cable from Black Diamond (details pending)
and upgrade the device yourself at
my.pieps.com. Pieps is the only
company that allows customers to install updates themselves.
The version number of the DSP Sport and DSP Pro software is displayed
immediately after turning the device on.
(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
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.
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

Transmitter, iProbe support,
the ability to
test the transmitting
frequency of another beacon, 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

Version 4.0 includes a new feature called a
Smart Transmitter. Here is a
brief explanation of this feature. (I tested this in version
4.0 and again in 5.0.)
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.

This version includes a handy frequency tester that allows
you to test the frequency of your friend's beacon. The image

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.
