Appendix B - Common Errors and
Their Solutions
Some errors occur more frequently than others. These common errors
and their solutions are listed in this appendix, according to the error
code that was returned from the function as indicated by IBERR. A full
explanation of all possible errors is in Section Four. Later in this
appendix are descriptions of error situations that do not return an error
code.
EDVR(0)
Error Condition: DOS error (see IBCNT for DOS error code).
Solutions:
• Check that GPIB.COM, CONFIG.SYS, and IBCONF.EXE are
in the root directory of your boot drive. (Enter DIR \ from the
boot drive and verify that these files exist).
• Check that CONFIG.SYS contains the line
DEVICE=GPIB.COM. (Enter TYPE \CONFIG.SYS from the
boot drive and verify that the line exists there).
• Reboot your system after you install the software.
ECIC(1)
Error Condition: Function requires GPIB-PC to be Controller-In-
Charge.
Solutions:
• Run IBCONF and make sure the board being used (GPIB0 or
GPIB1) is configured to be the System Controller.
• If executing board functions, call IBSIC to become Controller-
In-Charge before any other function calls that require that
capability.
• If control has been passed away with an IBPCT call, wait for it
to be returned with the IBWAIT function.
