If this is the first function you call that requires GPIB
controller capability, and you have not disabled System
Controller capability with
Interface Clear (IX) to make itself CIC. It also asserts
Remote Enable. If you passed control to some other
GPIB device, control must be passed back to you or you
must send IPC to make yourself CIC before making this
call. Otherwise, the ECIC error will be posted.
If you
System Controller, the GPIB-MAC returns all devices
to local mode by unasserting REN and asserting it
again. If you call lot without
MAC is not System Controller, the GPIB-MAC records
the ESAC error.
Refer to Appendix B for more error information.
