imgSessionConfigure takes several seconds

Hello,

I am now building an OCT system using 2048R InGaAs High Speed Linescan Camera. I use NI-PCIe-1433 to control it grabbing image. The camera configuration, imgSessionConfigure, takes about 5-7 seconds to pass which is very long and very wired. Are there any configurations I can to speed up?

I am just testing with the sample code called llgrab.c.

The machine has 19.5 NI-IMAQ, 19.5 NI-IMAQ I/O, 19.5 NI-IMAQdx.

Thank you! Look forward to hear any response.
