Hi Ajay,

Thanks for the reply, sorry to trouble you on weekend.

I am using the same open by serial number for initialization (making the communication) with FTDI, since serial number is auto indexed so first connected device set as Index 0, second device index 2, 3rd is 4 and 4th device index is 6.

While initialization even though all the devices are connected but still i am getting error 5103 and this is coming randomly (sometimes it communicate but some times it doesn’t ).

I am attaching the developed VI for your reference. Since the driver is password protected we cant see whats going in initialization.

Please guide on this.

Thanks,
Amit
