86 DAC488 Commands DAC488 User’s Manual

X - Execute

TYPE

System Command

SYNTAX

Execute command string.

DESCRIPTION

Commands sent to the DAC488 will result in no action until the unit is instructed to execute these commands. This is

done by issuing the Execute (X) command, usually as the last character of a command string. Commands sent

without an X are stored in an internal buffer and are not executed until an X is received.

Any number of Execute commands may be inserted into the same command string. If a command is used more than

once in a command string, the Execute command must be used before that command is used again.

EXAMPLE

PRINT#1,"CLEAR09"

Line 1: Reset the DAC488.

PRINT#1,"OUTPUT09;V4"

Line 2: Send V4 to the DAC488 command input buffer.

PRINT#1,"OUTPUT09;X"

Line 3: Instruct the DAC488 to execute its command input buffer. The

DAC488 will output 4 volts on the selected port upon receipt of the X.

PRINT#1,"OUTPUT09;P1 V4 X

P2 V3 X"

Line 4: Two Port Select (Pn) commands issued within the same string

require an X after each usage.
