DS275 – DS275 Line-Powered RS232 Transceiver Datasheet

Sun Nov 08, 3: Finally I changed the sub-d port and now it works however don’t know if in reality it will Grounds and Vdds are hidden with proteus so I don’t think problems come from there. Does not include photo attachment. When this happens, it starts sending AT commands to make the alarm call.

Make sure there is 1 ground across both systems. I have an inexpensive motion sensor auto dialer that dials my cell phone if it detects motion. No body can help me?

The user has 15 seconds to leave the room, then the pic waits a motion detection. Hi, thanks for your reply.

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 dtasheet be able to connect to a pc. Finally the pic dials a phone number through the modem to alert the user.


I have soldered some wires directly to the modem 1 for GND, 1 for 5 v.

I have an old external b. Do they make a digial sensor that will work or is there a attachment that will change analog to digital. You are talking about a camera and send the picture through MMS or email.

Once the call has been made and the modem detects that the call is ended, it returns a numeric code that the datashet receives and change to detection mode again. Did you have a negative voltage between pin 2 dtaasheet 5 on the D-Sub? What you can see in the video is: The modem is turned on and the pic configures it to disable command echo, change to return numeric responses and turn off the volume of the modem speaker.

Mon Dec 31, 3: It is more complicated. You should turn off the comparators as part of your initial register setup. When it is detected the pic dials a fixed phone number and the user will receive the alert.

Here is my program: The advantage of modems is that you can interact with the phone line for making calls.

Do you know if there is an off-the-shelf version of a picture sending auto dialer??? Este sitio web utiliza cookies para que usted tenga la mejor experiencia de usuario. In the same way I datasheef the ds because it can communicate with a serial port without a capacitor unlike MAX Sun Nov 08, I would love to find a device that would do the same thing and send me a pic. Since it is analog it does not work on digital phone lines.

If some movement is detected, it reports to a pic microcontroller. Previous topic Next topic.
