READYCK
Purpose
Read or set the Ready check flag.
Command
Query
“READYCK 1”
“READYCK?”
Classic “READYCK=1”
“READYCK”
Remarks
The internal ready check flag is cleared whenever the PPC4 reaches a Not Ready (NR)
condition. The “READYCK” query returns the status of the flag. The flag is set by sending
the “READYCK 1” program message while the PPC4 is in a
Ready condition. The
“READYCK” program message query can then be used at a later time to determine whether
a
Not Ready condition has occurred since the ready check flag was set.

REMOTE
Purpose Lock out the front panel keypads during remote operation.
Command “REMOTE”
Classic “REMOTE”
Remarks The PPC4 goes into remote mode whenever communications take place. The user can
return to local operation by pressing

. The REMOTE program message locks out the front
panel completely. The only way to unlock the front panel after the “REMOTE” command is
using the “LOCAL” program message, the IEEE-488 “GTL” command, or by cycling the
PPC4 power.
