GPS Data Logger Software - BT747

IMPORTANT: BT747 is updated with a CERTIFICATE to comply with JAVA 7 (1.7.0_51) security.
(I bought a trusted certificate (provided by a trusted authority) for about $300.  Received it on Jan. 17, 2014.
Thank you (!) to the users that donated a bit (thanks!) to partially cover the cost of the certificate.
 If every person using BT747 would donate $1 the cost would be covered in about two weeks (luckyly for you, I did not wait to cover the cost).

Installing the desktop version of BT747 for GPS control is fairly easy through the 'Java Web Start' system.  This system works on Windows flavours, MacOS and Linux.

To download zip files follow this link.

On Ubuntu it is recommended to Install sun-java6 first

For easy installation (RECOMMENDED!), use one of these links:
Try the desktop version of BT747 or Install the desktop version of BT747
Try the development version, Install the current development version or keep it up to date automatically.

On recent machines or in case of trouble with the serial link: BT747 Latest using RxTx 2.2pre2 (RxTx dev version) for Windows 32 & 64 bit, MacOSX, Linux or Install the development version using RXTX2.2pre or Install the stable version using RXTX2.2pre

Since today BT747 (BT747 Desktop RXTX 2.2.app) doesn't start on  my macbook anymory and I get the error message below. The last 1.5 years all worked very well and there was no java update the last days.
