How to change GPIB device primary address

Hello ;

       I'm new comer to GPIB filed. We want to integrate one device into our antomatic test enviorment.

The GPIB primary address of the device is shown as 25 in NIMAX(seen as attached). We intend to change the primary address to 4. Could someone tell me how to change the primary address of this device?

thanks!
