In recent months our 6 year old VB6 software has exhibited some problems. We are not yet sure about what causes the problem but it appears that the Medoc VB6 software package loses control of the TSA resulting in "Fast Drive" errors and unstable temperature ramps. The problems started about the same time
some new antivirus and security protection was installed on all the dental school computers and we suspect some interference.
. We have, so far, not been successful in fixing the problem, but the VB.NET version below seems to do better although still in early development (the project had been interrupted by other, then, more pressing projects). TSA UNC Application under test. (August 25, 2011). And its default file. (August 25, 2011).
2010 VB.NET (2008) Vervion
In Alpha Test.
Needed Medoc Files
Medoc Files to be included, with all versions, in the same folder as the executable file above must be purchased from Medoc with the TSA SDK package ($3,200 as of August 2008):
"SHOVAL32.EXE", "AAA.DRV", "Options.ini", "VATOD.DRV", "VSAATOD0.DRV", "VSAATOD1.DRV", "VSATABLE.DRV", "BLACKBOX.DAT" and "LogVAS.drv".
Press twice on SET button on Pathway front cover display. Set-point temperature will appear (by default 5°C).
Set 8°C using UP and DOWN arrows.
Press twice on the FNC button.
Audible Alarm / Coolant Level
It is suspected that a Pathway audible alarm may sound when the cooling water reaches a critical level
even though the refrigeration unit front panel red LED is not lit.
Adding some distilled water as indicated in the "Pathway Operating Manual" (Chapter 13.1 page 74 in the 2005 version) has fixed the problem in the past. Make sure to use 95% distilled water (NOT sterile) and 5% alcohol.
