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 PPC3 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 PPC3 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 PPC3 goes into remote mode whenever communications take place. The user can
return to local operation by pressing the [ESC] key. 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 PPC3 power.
