TYPE

EXECUTION
Immediate
SYNTAX
X
Execute preceding command string.
DESCRIPTION
Most commands are interpreted and processed as they are received but are not executed until the Execute (
X
)
command is issued. Commands sent without an
X
are stored in an internal buffer and are not executed until an
X
is received.
While a command line is being interpreted, the front panel LEDs will not be updated. These LEDs will only be
updated when the unit is in a ready state. In order to determine if the unit is in a ready state, perform a Serial
Poll for the ready bit (4).
If multiple system commands are used in the same string, each use of the command must be followed by the
Execute (
X
) command. Any number of Execute commands may be inserted into the same command string.
