Re: Scale Interface

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

Hi Cletus,

I do communications with a Mettler/Toledo Jaguar and JagXtreme scale 
interfaces.  I don't have any experience with Compsee, though.

Most scales can be programmed to report the weight in several different 
ways. I know that the ones we have are able to send the weight 
automatically when the weight on the scale settles. They're also able to 
send it when the user presses a button on the scale interface.

On the Jaguar models that I work with, you're able to do more complex 
things as well. I can write entire programs that run on the scale and can 
do whatever you dream up.  The JagXtreme even has a sockets interface so 
it can connect TCP/IP to my RPG programs and talk to them.

My recommendation to you is to find the manual for the scale. You might 
even want to talk to the manufacturer to see if they have a separate 
programming manual (separate from the basic "owner's manual") since that 
will help you out tremendously.
