TITLE	VER	USE WITH
PPC4™	1.2.6.14	PPC4 (including -AF models)
Instructions:
Download the file by clicking on "PPC4 v1.2.6.14.bin". Run Winflash and select the file downloaded as the file to write to the product. Make sure the correct COM port of the product is connected to a RS232 port on the host PC. Use a null modem cable to COM2 port of PG7000 Piston Gauge. Use a standard RS232 cable to COM1 port of PPC, PPC, RPM and molbox. The updating of embedded software should only be performed after given specific instructions to do so from a Fluke Calibration Authorized Service Center ». If the update isn't performed properly, your product will be inoperable until it is.

Ver 1.2.6.14 (2020 Mar 07) Fix: Issues related to BG model IL bypass valve not closing to allow normal operation if a vent process is aborted before the vent process is complete Fix: An issue (on PPC4 Basic front panel interface only) where a date greater than 20191231 cannot be entered on the front panel calibration or Time&date menus
Ver 1.2.5.0 (2017 Mar 26) FIX: (PPC-625) Improved control performance for low negative gauge setpoints.
Ver 1.2.4.8 (2016 Jan 11) FIX: (PPC-620) Control may not respond to a new target after 24.5 days of being on. FIX: (PPC-621) PPC4 phase 2 high pressure controller unable to reliably float 200 kPa/kg PC (IP & DP commands not working right)
Ver 1.2.3.38 (2014 Apr 14) ADD: (PPC-614) Increase max number of exercise cycles from 50 to 999999 ADD: (PPC-613) Allow 30 Advanced AutoTests instead of 20 FIX: (PPC-382) Leak test does not work with external RPT FIX: (PPC-386) PPC4 AutoTest does not permit negative gauge mode setpoints FIX: (PPC-389) Watchdog error if IH Q-RPT was last in negative gauge mode and switch to X1H Q-RPT in RPM4 in absolute mode and set pressure lower than ATM FIX: (PPC-393) Decrease sensitivity of knob operations FIX: (PPC-394) PPC4 vent valve opens and then closes during data acquisition at gauge 0 point at the start of COMPASS test FIX: (PPC-396) Absolute mode zeroing with an active external RPM4 QRPT does not work (GUI) FIX: (PPC-397) Autotest not allowing pressure less than full scale FIX: (PPC-405) Control reference setting resets to "Manual Atmosphere" after power cycle FIX: (PPC-410) ARANGE= command will accept negative absolute range requests when RPT to use is explicitly given FIX: (PPC-385) Memory Fault 3.127 FIX: (PPC-409) Cannot run VAC config when in absolute meas mode (Basic UI only) FIX: (PPC-398) mmH2O,20 and mmH2O,60 are incorrect. FIX: (PPC-399) Unit designation for inches and mm of water need to be changed to the current convention of inWa and mmWa from the inH2O and mmH2O. FIX: (PPC-362) Default hold limit minimum for G15k should be 10 ppm of 30 kPa (0.0003 kPa) FIX: (PPC-160) It is not necessary for config to be in absolute or gauge units. It should be able to run in either [GUI].
Ver 1.2.2.63 (2012 Mar 12) ADD (PPC-373):Support for auto-ranging a utility sensor on future Cockpit PC software. FIX (PPC-353):Replace DH Instruments PPC4 screen with new Fluke Calibration screen saver. FIX (PPC-367):Jog feature in the GUI does not work. FIX (PPC-376):GUI's AutoTest feature not working with utility sensor. FIX (PPC-378):The ARANGE command does not work when a utility sensor is specified. FIX (PPC-379):Cannot use or select a utility sensor in GUI autorange screen. FIX (PPC-384):Use full resolution on the reply of the HL and SS command to ensure they do not indicate '0' when they are actually a small value. FIX (PPC-371):ABORT command does not abort CONT measurement. FIX (PPC-388):"Lo" pressure control mode should not use the slow down valves when ramping. Ver 1.02 (2010 Sep 15) ADD (PPC-319):The A14MU RPT is now supported. ADD (PPC-334):The BA100K is now a supported QRPT. CHG (PPC-359):The default uncertainty Span value was changed to 0.003 from 0.0024 for a Standard QRPT. CHG (PPC-355):SI and US model PPC4s now support the same set of available Autorange values for a given QRPT. The default range values are still consistent with the SI and US model definitions. Previously a US A1000 psi PPC4 could not be Autoranged to 7MPa. FIX (PPC-358):Setting low negative gauge pressures did not use the proper internal controller logic preventing the pressure targets from being achieved. FIX (PPC-342):When the security level prevents changing a value, the PPC4 allows the field to be edited but did not restore it. The security protected fields are now properly restored. FIX (PPC-327):The hold limit and stability limit values were not preserved after a power cycle unless the unit of measure, resolution or upper limit was also changed. FIX (PPC-322):The "ARANGE" command did not work properly when attempting to auto range the BA 100K. FIX (PPC-311):The secondary password used when the original password is forgotten, did not allow the security level to be changed. FIX (PPC-363):Selecting the maximum resolution on the PPC4 basic interface creates a memory fault.
Ver 1.01a (2010 Jan 22) CHG: Updates a factory setting associated with low absolute pressure control. Affects new builds only.
Ver 1.01 (2009 Dec 21) ADD: Support for “Phase-II” low pressure control when a Phase-II generation module is installed ADD: Support Ethernet as a remote interface option. FIX: “*OPT?” command response missing a comma FIX: A large negative measurement does not generate an under-pressure message on all RPT types.
Ver 1.00d (2009 Jun 15) ADD: Chinese (Simplified), Chinese (Traditional), Czech, English, French, German, Italian, Japanese, Portuguese, Russian and Spanish are supported in the advanced user interface. An Earth icon on the main run screen accesses the language selection screen. FIX: PPC4 with external RPM4 active in negative gauge mode alarms and will not set pressure when indicated pressure is negative.
Ver 1.00c (2009 Mar 02) ADD: Support a "knob jog" secondary pane option when the PPC4 is actively controlling a pressure in dynamic control mode. ADD: Command Interpreter functionality added to interpret the remote commands of other pressure controllers. CHG: Support up to 20 Advanced Auto Tests rather than 10. This firmware release will erase any existing Auto Tests. FIX: AutoTest with non-zero start point still displayed "0 to ..." as label FIX: Cannot edit date for barometer calibration in standard display model. FIX: Change user unit coef range from "0.001,1000" to "0.000001,1000" FIX: PON bit of the "*ESR?" query always clear.
Ver 1.00b (2008 Aug 12) FIX: Low pressure control can be unstable, and not get Ready. FIX: Pressure control should detect instability and make necessary corrections in control times to stabilize.
