multiple device simulator

[nicovar]

Hi,

I develop a program in visual c++ to test an other program.

In my PC, i have 2 PCI GPIB Card, 1 card to send and receive data to the instrument and the second to simulate the instrument.So the 2 card are connected and i have not instrument.

My problem is in the test program, i must have 4 device in a card for simulate the instrument and if i use ibdev function to initialize the board, i have ECIC error. And yet the second card is configure in controller.

thanks

Hi,

On a GPIB bus, you must have only one controller in charge (CIC). And the ibdev(...) function can only be used with a CIC.

This error could be caused by the fact that you use the ibdev(...) function with a slave device, or by the fact that you have more than one CIC on the GPIB bus.

Please check this two points. It shoudl solve your problem.

Regards,
