9.7 Trouble Shooting - IEEE-488 / GPIB
This section provides guidelines for resolving communication problems that may occur when
using the 2001RP with or without the KDCGUI software with a IEEE-488 / GPIB interface.
Symptoms:
1. Unable to verify connection to the power supply through IEEE-488 interface. Time-out occurs
any time an attempt is made to verify connection.
Things to check:
1. Is the interface option set to use the IEEE-488 interface instead of the RS232C interface?
The DIP switch on the right side panel of the power supply is used to select the desired
interface mode. Refer to section 0. If the GPIB option (option -IF) was ordered, it should be
set this way from the factory but may have been changed after shipment).
2. Does the bus address selected in the System, Interface dialog match the address set using
the DIP switches on the 2001RP? The GPIB address selected must match the settings on
the DIP switch. If changes are made to the DIP switch setting, the power supply must be
cycled off and on to have the new settings take effect.
3. Did you connect the cable in correctly and are both ends of the GPIB cable securely tied
down?
Select the GPIB interface and click on the NI-488.2M Settings tab. An Advanced button at the
bottom of the screen will provide access to the Bus Timing parameter. Set this value to 2 sec to
operate with the power supply's GPIB interface.
