Slow data transfer when reading from GPIB device (Horiba CCD 3000)

[Itro]

Hello eveyrone.

I'm trying to communicate with  a CCD camera (CCD 3000 - company Horiba (former Jobin Yvon)))

The connection is made over GPIB (PCI)

The CCD device is quite old and wont support the standard GPIB commands  (e.g. *IDN?)

The problem I'm having is that after I take a photo,  when I want to read the data from the CCD

It takes about 10 seconds before all the data arrived to the computer

the time delay is proportional to the pixels array size:

when I take the data from the entire area of the CCD (1024*256 pixels * 16bit =512kB)

It takes 10 seconds

when I regard 4X4 pixels  as 1 pixel (this is done by the hardware)  (256*64 pixels * 16bit = 32kB) it taks about a second

What can be the cause for this kind of problem

how can I solve it ?

Thanks

As you said, the camera is quite old.  Maybe 50kB/s is its max data rate (probably really 56kB/s).

Thanks for the reply

But This is not the case

The CCD is made for Lab experimentation and is supposed to be able to take photos almost continuously

What does taking photos continuously have anything to do with the camera's ability to transfer the photo "data" to a PC?

Go ask the manufacturer. Everything is else is conjecture and a waste of time.

Yes

I'm sorry but this is actually the case for this CCD

I was so certain that this is impossible that I post the question here before the Manufacturer replied...

Sorry for wasting your time
