1 Change Note hwos Firmware 3.09.4
|
|
|
2 ================================
|
|
|
3
|
|
|
4 - When diving in CCR or pSCR mode: An attention and a warning for the gas
|
|
|
5 density has been added. The attention will be given when the density
|
|
|
6 of the current gas mixture reaches 6.0 grams per liter. Upon reaching
|
|
|
7 6.5 grams per liter, a warning will be given. The checks can be enabled
|
|
|
8 or disabled via the menu CCR/pSCR setup > more.
|
|
|
9
|
|
|
10 - Incremented upper limit for SAC Work to 80 l/min to ease usage of the
|
|
|
11 OSTC gas needs calculation in Rock-Bottom mode.
|
|
|
12
|
|
|
13 - Faster response to button events while in dive mode.
|
|
|
14
|
|
|
15 - Hardened all USB/Bluetooth communication against data losses and timeouts.
|
|
|
16
|
|
|
17 - Fixed Bluetooth item disappearing from menu.
|
|
|
18
|
|
|
19 - A new Firmware Recovery Feature has been added: the currently active firmware
|
|
|
20 can be backed-up and restored later on while other firmwares have been loaded
|
|
|
21 thereafter. The feature is accessible via Settings -> System Settings ->
|
|
|
22 Reset Menu -> Reboot and becomes available with the first firmware load after
|
|
|
23 the V3.09 beta 4 (or later) is already on the unit.
|
|
|
24
|
|
|
25
|
|
|
26 Change Note hwos Firmware 3.09.2 + 3.09.3
|
|
|
27 =========================================
|
|
|
28
|
|
|
29 - Added a function to acknowledge pending alarms, attentions and advices
|
|
|
30 so that the exclamation-mark sign disappears: after pressing the left
|
|
|
31 button until "Ackn?" appears, a press on the right button acknowledges
|
|
|
32 the current alarm, attention or advice and suppresses the related sign.
|
|
|
33
|
|
|
34 - Bugfixes: NDL not shown in big layout, external sensor not selectable,
|
|
|
35 flash-write operation on some OSTC hardware, graphical garbage in depth
|
|
|
36 output in big layout when deeper than 100 m.
|
|
|
37
|
|
|
38
|
|
|
39 Change Note hwos Firmware 3.09.1
|
|
|
40 ================================
|
|
|
41
|
|
|
42 - Removed option 'ascent speed', ascent calculation is done with a fixed
|
|
|
43 speed of 10 meters/minute now (equals the ascent speed limit by Bühlmann).
|
|
|
44
|
|
|
45 - Improved calculation accuracy of the initial ascent. Remark: this will
|
|
|
46 have a slight impact on the resulting deco schedule compared to firmware
|
|
|
47 3.07.
|
|
|
48
|
|
|
49 - The deco calculator now figures in the salinity setting.
|
|
|
50
|
|
|
51 - Aligned logbook and last dive summery of avg and max depth regarding
|
|
|
52 rounding and incorporation of salinity setting.
|
|
|
53
|
|
|
54 - Done some fine-tuning of depth outputs when using imperial units (feet).
|
|
|
55
|
|
|
56 - In dive mode, sometimes the temperature was not shown any more after a
|
|
|
57 gas change - fixed now.
|
|
|
58
|
|
|
59 - The menu system around setting up the dive mode & settings has been
|
|
|
60 decluttered. All settings are now sorted into the groups dive setup,
|
|
|
61 deco setup, SAC (gas needs) setup, ppO2 setup and stops & depths setup.
|
|
|
62
|
|
|
63 - There is a new option "Swap on empty" in Dive Setup -> SAC Setup.
|
|
|
64 It is only effective if "CalcGas(B/O)" is switched on, too. If both
|
|
|
65 options are switched on, the deco calculation will switch to another
|
|
|
66 tank (i.e. gas) once the tank of the current gas is calculated to be
|
|
|
67 used up.
|
|
|
68 This function can be used to automatically calculate a contingency in
|
|
|
69 case of running out of a deco gas, as the deco calculation will then
|
|
|
70 continue to calculate a deco making use of the spares from the another
|
|
|
71 gases carried. Another application is with two or more tanks holding
|
|
|
72 the same gas (i.e. independent double configuration, side-mount), as
|
|
|
73 the calculations will then take the cumulative amount of gas carried
|
|
|
74 into account before raising a gas needs attention or alarm.
|
|
|
75
|
|
|
76 - Fixed the urge of the better gas hint to always favor one specific gas
|
|
|
77 out of a set of two or more gases that have the same change depth.
|
|
|
78
|
|
|
79 - For dives done on firmware >= 3.09 the logbook will have one more page
|
|
|
80 showing the tissue pressures and supersaturation levels as of at the
|
|
|
81 end of dive (i.e. when surfacing).
|
|
|
82
|
|
|
83 - As long as a gas or diluent is currently selected as breathed, it can
|
|
|
84 not be set into the lost state any more.
|
|
|
85
|
|
|
86 - When changing the battery or doing a cold start, the current CNS value
|
|
|
87 does not get lost any more.
|
|
|
88
|
|
|
89 - During loading of a new firmware the clock will not loose time any more
|
|
|
90 (on old firmware it became late by about 15 sec on each firmware update).
|
|
|
91
|
|
|
92 - When run from a 3.6 V battery (either replaceable or built-in), the
|
|
|
93 surface mode timeout is now extended to 4 minutes before going to sleep
|
|
|
94 mode. If the OSTC is run from 1.5 V disposables, the timeout remains at
|
|
|
95 the previous 90 seconds to save on battery runtime.
|
|
|
96
|
|
|
97 - Internal improvement: the code for the internal storage system and for
|
|
|
98 the communication system (firmware uploading, dive data downloading)
|
|
|
99 has been re-factored to secure maintainability for the next years to come.
|
|
|
100
|
|
|
101 - Internal improvement: the scheduler for the dive mode calculation plans
|
|
|
102 (fTTS, bailout) has been completely rewritten for better maintainability.
