Error Codes and Solutions
Solutions
1.
Make sure that the GPIB address of your device matches the GPIB
address of the device you want to write data to.
2.
If you are using board-level functions, make sure that your device is
properly addressed to listen before writing to it by using ibcmd or
sendsetup.
3.
Use the appropriate hex code in ibcmd to address your device.
4.
Check your cable connections and make sure at least two-thirds of your
devices are powered on.
5.
Call ibpad (or ibsad, if necessary) to match the configured address
to the device switch settings.
6.
Reduce the write byte count to that which is expected by the Controller.
EADR (3)
EADR occurs when the GPIB board is CIC and is not properly addressing
itself before read and write functions. This error is usually associated with
board-level functions.
EADR is also returned by the function ibgts when the shadow-handshake
feature is requested and the GPIB ATN line is already unasserted. In this
case, the shadow handshake is not possible and the error is returned to notify
you of that fact.
Solutions
1.
Make sure that the GPIB board is addressed correctly before calling
ibrd or ibwrt.
2
Avoid calling ibgts except immediately after an ibcmd call (ibcmd
causes ATN to be asserted).
