hi,
i need to ask how the connection between PIR sensor and SK40C and Siemens TC35 GSM developement board?
is the connection still the same with SK28A board(smart intruder project)?

The SK28A has 3port if im not mistaken..while SK40C has 4port...so if i want to connect 4 PIR sensor..i just pin it to each port A,B,C,D right?

The source code for SK28A can just be copy to SK40A but with few changes and additional command correct?
Is there any mistake with my explaination? Thank you very much...

Basically is correct, try it first. Share what you have done and other forumer can advise accordingly.

Tq for the feedback,
i need to ask, i want to test the GSM board to send msg,
i using the rs232 interface port connect to UART TO RS232 converter and UC00A to USB port at my laptop..however when i power up the GSM( simcard insert already) and also open the X-CTU interface, my laptop still cannot detect the GSM modem, and the X-CTU interface didn't detect any COM connection.

did I missing any steps..? tq..

Confuse with your connection, can share a photo of the wiring connection from computer until the GSM modem?

This is the pic of the GSM setup,
any mistake please point it out..tqvm

Can anyone help me how to setup the GSM step by step?
what i understand, first step is:
1. insert a SIM card
2. connect the GSM adapter power 12V 2A
3. connect the GSM with UART RS232 converter and UC00A for USB port connection
4. installed the Hyper Terminal, (i am using X-CTU installer from cytron website)
However the interface is different from the tutorial, can anyone guide me using picture if possible how to configure the setting..
5.After power up the GSM module, suppose the X-CTU will detect the GSM, but the opposite happen..
Tqvm to those who helping me..

Try send 'AT' command and Enter. If connection right and select right COM, it should give 'OK'
See example GSM response here using PIC and chipKIT.

Tq, but i still have problem..it say cannot detect the COM...is it coz im using USB port not RS232 port?
The GSM blinking just as expected showing its working with the SIM card inserted, however cannot be detect by my laptop..
Do i need to installed some other software? or i need to use a desktop with RS232 port(difficult to find actually..)?
Pls any advice?tqvm

Sorry, another question,Why is it still say it cannot detect the port?? any driver need to install first??
in the X-CTU suppose we can choose which port to use from the list, but there is no list...i try to check at the device manager but it say no driver..someone can help me pls? tqvm
