RS232/Socket Programming

[abpsoln]

Has anyone come into contact with this before?

 

[abpsoln]

can recommend some resources for learning TCP/IP socket programming and C++ terms?

Which are you actually interested in? serial comm or network socket? They are not the same you know

 

[abpsoln]

1. My boss requires me to work on RS232 serial comm
2.and also socket programming on TCP/IP to transport data

 

[abpsoln]

This is the pin out of RS232

RS232 Comm programming is of lower level than socket programming since you need to take care of more low-level communication details like baud rate etc. Don't have much experience with RS232 Serial Communication.

Socket programming is fine with me. Often doing it.

This is a forum, so you just post what you want to know and see if anyone has anything to response you.

DB9 should be the other way round?

 

[hawthorne]

long long time ago developed an app to comms via RS232 on specialised hardware before

What kind of task you are required to accomplish?

Simply asking about RS232 programming is not helping in anyway.

Please provide us more information or precisely what type of machine/device required to communicate via RS232/RS232C commonly found on CNC machines for DNC operation. You might not need to learn about programming if all you need is to establish communication between a COMM port and a industrial machine via RS232/RS232C regardless of DB9/DB25 port.

Hi there,
I am trying to build and IDS systems,
RS232 is connected to sense data input from raw data for processing
RJ45 cable to connect to the internet for monitoring
Digital input output is used for is used for voltage sensing.

The idea is to build a intrusion detection system such that when someone tried to cut the wiring of 12V battery it will rely on the battery,

Just out of the box, do you need RS232 to detect a flip in voltage ? I say a microcontroller like Arduino can do the trick. Have a resistors divider to patch the 12V to one of the input pin at 5V. Have an ethernet shield to the Arduino, run a simple loop watching the input pin, once it drop for more than a certain threshold counts (prevent false positive), send a SNMP trap out to an system out there. A very simple trigger into the IP world.

I am looking for one microcontroller with:
8 DIO
1 RJ45
1 RS232

Thanks.I may just suggest this.

Have you heard of ADAM 4051 modules before?
Similiar?Difficult?

No idea. Microcontroller is not my specialty. Arduino is just one of my lesser interest, you can call it.

are they different parts to be assembly together?
must buy?

The main board is a separate purchase from the various Shields boards. If you want something complete, you probably should look at what you have suggested yourself earlier on.

I'm just suggesting something you can try out, you have to do the research

 

[abpsoln]

This is the layout I am using

 

[abpsoln]

Is it possible to control the microprocessor using the RS232 interfaces,
such that when DI is 3 then I will trigger an alarm to send an email to the server?

ADAM-4501 is DOS based controller. You need to write software using Borland C and compile it in DOS mode to controller the RS232/485 etc that is on this device.
