Hi John, What was your source for updating the motherboard on the old chelton IDU. To my knowledge the newer firmware versions 6A or 6B require a motherboard ( pfu systems G2 boards with Celeron 650 or higher speed). ? Kamal T N1104T 99% completed 4p

Hi Bob,
TAWS alive and well now. I had an older Chelton ( in reality is was a Sierra Flight Systems box) in MFD two position and newer Chelton as PFD. Brent had updated the newer one to latest SW and latest terrain DB. The older Chelton had latest firmware version but I think older terrain DB. Recently Brent updated my 2nd newer Chelton and put in new terrain DB. I installed it and the problem with TAWS disappeared. I thought PFD would push terrain DB to MFD, but I guess this did not happen. I figure competing DB versions threw the Chelton/Pinpoint system into a quandary and it just failed the TAWS as a result.
Thanks for your thoughtful input.
John
