USB Communication with LabVIEW

[Sundar...]

Hi ,

I am trying to Communicate across 2 PC`s with USB based communication.

However  I am unable to this with LabVIEW since this is not detected as a COM port

but shows as an data transfer cable shown in image below.

I am currently using this cable ( BF 7313) Bafo make.

If any one has currently tried using this mode of communication ,

please let me know.

Thanks,

Sundar.

Do you have a manual from the supplier?

There is no programming manual from the supplier as such .

however there was a single sheet that says how to connect two PC`s 

with his custom drivers and transfer data between them.

The purpose of this cable is to migrate an older PCs data and applications to a new Vista based computer.

To make use of this cable, you need the Windows Easy Transfer application.

I don't believe that you will be able to use this cable to quickly and inexpensively connect two LabVIEW apps. 

I would suggest looking at USB-to-Ethernet adapters and transferring data via TCP/IP or defining share points on the two PCs and mapping drive letters.

You could also use USB-to-RS232 adapters and move data with NI-VISA, but the adapters will probably cost about the same, require additional programming and be much slower than Ethernet.

Thanks Philip,

I need this USB to USB with some sort of bridging inbetween,

since I need to very the communication protocol due to lack of 

hardware from the customer.

Any idea what kind of a bridge these cable use to network the 

two PC`s via USB; I suppose they use a USB ->serial <=>serial->USB.

Each USB to RS-232 adapter on each PC will have a driver disc that will create a virtual com port on each PC.  To connect the two RS-232 connections, you will need a female-female null modem cable.

I guess the cable that  I am currently using, is similar to this one described here.

In the article you provided they talk about two working modes, USB and Ethernet.
If your cable also has those two modes, using the ethernet mode you maybe be able to use it in LV with TCP/IP vi's.

Just a guess
