Menu preferences are not normally retained after the
power is removed from the instrument. To make (a)
menu preference(s) permanent, make the desired
change(s) to settings first and then proceed to the
section Storing the Menu Preferences to make the
changes permanent. Following this procedure will put
the settings into non-volatile memory and allow them
to be restored during instrument power-up.
Each message to or from the 1256 must end with an end-of-line
(EOL) character known as a terminator. You may select the EOL
terminator to be any one of the following:
•Carriage return (CR) only
•Line feed (LF) only (for non-terminal-based applications, such
as controlling via LabVIEW programs)
•Carriage return and line feed (CR-LF)
The factory default is line feed only.
To select the EOL terminator, proceed as follows:
1. Press the top key. Rotate the knob until the top line reads:
>-----SETTINGS-----<
2. Select line 2 (next to top line) by pressing the second key. This
selects line 2 so that you may choose the type of setting to
