You're welcome, glad it helped.
DCEraser is a windows program and should run from the 'start' menu ( or desktop) not the command line. It is packaged in a 'Wise for windows' selfinstalling executable and will be shown in the start menu under 'JCONN'. Once the program is running select the proper comm port from the list box, it automaticly updates itself for all available ports. Click the 'Do It' button and that's it.The program will report status upon completion. It has never been tested on a Vytec, but I've tested it on the gekko and vyper. I'm about 99% sure it'll work fine as they use identical memory models.
The Datum tag in the downloaders output is the dive profile. Each "Datum" tag is the info written at a single sample, On the gekko/cobra,vyper,vytec this is a single number, it can be more. There are also "Event" tags in the profile, they are the 'bookmarks' listed in the manual. The computer doesn't actualy store the depth in the profile, data is written from start of dive as a 'Delta' of the depth from the last sample.
If we use these numbers as Datum points 12,9,7,9,1,1,0,0,-5,-5,-4,0,0... and assume you used a 30 sec sample rate then it reads : from the surface, in the first 30 sec you went down 12 ft, the next 30 sec you dropped 9ft more, then down 7ft, ect. A negative number means you came up that many feet. In the above sample,You went down to 39 ft over a 3 minute period, stayed there one minute then came up to 25 ft over a 1 1/2 min period and stayed there for 1 minute.
