Third Party devices detection

[Sambaiah Gunakala]

Hi all

In LabVIEW How to detect the third party devices pragmatically that are connected to our host PC.

That's an extremely broad question. Are the devices PCI cards or connected through a communication port? What type of communication (e.g., RS232, GPIB, Ethernet, USB)? What type of devices? You are going to need to provide some information about these for people to have an answer.

I think you mean programmatically, but it depends on what interface your devices use.

My instrument containing the following interfaces:

1.) Ethernet

2.) RS-232

3.) GPIB

The instrument manufacturer should have documentation detailing the use of each interface. If they don't provide a protocol for detection, you can fabricate your own once you understand their specification.

I agree with asbo that you're going to need to read some manuals. Some thoughts are:

• Ethernet has a ping to determine if an IP address is used, but that won't tell you what is connected.
  
• RS232 will have something or nothing connected to the port.
  
• GPIB instruments typically use SCPI commands, so a "*IDN?" will tell you what is there. Some RS232 and Ethernet devices do the same.

Thanks for clearing the doubts
