GPIB devices not found

[thomasd6]

Hello all, am using an agilent power meter with labview via GPIB/USB and keep getting errors which i do not understand.

so i tried to debugging using NI MAX. Although the actual cable is found, it can not find the intsrument at the end of it when using

the scan for intsruments. 

I tried to using the serial port which seems to work fine.

I tried a different GPIB cable to rule it out and had the same trouble.

looked at the passports to ensure that the correct ones were enabled, which they are.

Can any one please help as to why  i can not find any GPIB devices using IN MAX, also how can i fix this problem.

Many Thanks

Daniel

Hi,

The need to setup the meter to communicate over gpib through the front panel. It can only be setup to use gpib or rs232, not both.

Check the user manual.

How is this done, i can not find the option for this.

 As the progamming guide tells me to look in the users manual, and the users manual refers me to the programming guide.

Play around in the menus.  There should be something like I/O Bus or Communications.  It's hard to give details without knowing the exact instrument.
