You are talking about a camera and send the picture through MMS or email.

Since it is analog it does not work on digital phone lines. Mon Nov 09, Finally I changed the sub-d port and now it works however don’t know if in reality it will No body can help me? What you can see in the video is: I have an old external b.

Make sure there is 1 ground across both systems. A passive infrared sensor PIR is waiting for a person to enter a room.

I would love to find a device that ds257 do the same thing and send me a pic. Here is my program: Your invention is great but it helps if you have the technical smarts to do it. Users browsing this forum: Does not include photo attachment. Once the call has been made and the modem detects that the call is ended, it returns a numeric code that the pic receives and change to detection mode again. Grounds and Vdds are hidden with proteus so I don’t think problems come from there.

The modem is turned on and the pic configures it to disable command datashset, change to return numeric responses and turn off the volume of the modem speaker. Do they make a digial sensor datasbeet will work or is there a attachment that will change analog to digital. The pic is coded in mikroC and my problem is at the level of the connexion between DS it’s a max without capacitors and the SUB-D port the circuit will be able to connect to a pc.
