Wow,
Same thing happened to me never have gotten it wet I updated it and when the connection closed it never came alive so now the Postively Outstanding Software HAS KILLED MY (#)$*)(#$#@*($@#$ *(@_#_$*( COBALT.....NICE!!! RON any suggestions or do I now have a #)($#)($*#)($)( paper weight.
The first thing the firmware update program does is to delete the previous program in the Cobalt. If it doesn't complete the process, or isn't pointed to the correct file on your local hard drive, it won't have a new program to install, and it won't come back up. But nothing fundamental has been harmed, it's just a matter of getting the correct firmware loaded into the Cobalt. This should be pretty simple:
1) Connect the USB side of the adapter to the Cobalt, and plug the USB cable into both your PC and the Cobalt adapter. Since the unit is dead, you won't see a "connected" message.
2) In the PC updater/ dive log program, select "flash the DC" from the File menu, then click the button on the top of the main screen that says "Locate Flash". Using the window that comes up, locate the flash file that you downloaded and unzipped from the Atomic site, wherever you have placed it on your local hard drive. It will be called "
Cobalt_110_EndUser_4.hex"
If it is any other file, or if it still has a .zip extension, the update will fail. There is a picture on the
Atomic Aquatics Cobalt Updates web page that shows what this should look like. Select Open in the window, and this file name will be placed in the field opposite the "Locate Flash" button. If it's not there, stop, go back, and find the file.
3) Click the Start button just under the "Locate Flash" button. You should start to see little balls floating from the computer picture to the Cobalt picture, and an occasional update of the data read. After something under two minutes, the process should complete, "connection closed" will appear on the PC screen, and your Cobalt should come up to the set time/ date screen a few seconds later. If you see "connection closed" immediately after starting the update, then the program did not find the right file on your PC.
This will work even if the Cobalt has been previously killed by a failed upload attempt. If you have any problem with this PM me and I will help you work through it. Rest assured, there is nothing you can do in attempting to update the firmware that will actually damage the Cobalt.
Mac users can do
almost the same thing, but they need to find the file inside the window that comes up when they click the "start update" button, and if they are starting with a "dead" Cobalt, they need to unplug and replug in the Cobalt USB adapter AFTER they both click the start update button AND locate the Cobalt_110_EndUser_4.hex file and select OPEN, i.e. after starting the update process.
