Re: Compass Software

I kinda tried that the other day, but musta done something wrong cause I
wiped out the guy's code. If you connect and you dont get a mismatch
error...then I can change the user code...save?...then send to panel right?
I "think" I may have messed up by Viewing Upload somewhere maybe?...maybe
thats how I unloaded the code.

| It isn't always necessary to copy the panel.  Remember that Compass will

| changing something at the keypad and not telling you.
|
| The trick is to contact the panel before you make any changes in Compass.
| If you get the warning message, you upload.  Otherwise, you remain on line
| with the panel, modify the program, save, and download.

| Ademco seems to break the programming into blocks on the larger panels,
| each of which has a CRC.  So, you aren't really uploading the entire
panel,
| just checking the CRCs for each block and copying the blocks that have
| changed.  I assume on the smaller panels, it's quicker just to copy the
| whole program rather than breaking it into blocks.
