NOTE
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.
Using Microsoft
HyperTerminal
One of the easiest ways to manually control the 1256 through the
RS-232 interface is to use HyperTerminal. HyperTerminal is a
terminal emulation program that is included with Windows 95 and
98.
Before using HyperTerminal, or any other terminal emulation
program, set up the 1256 RS-232 parameters as follows (refer to
the above sections for details about accessing these settings via
the front-panel controls):
Baud
rate: 9600
Data
Bits: 8
Parity:
None
Stop
Bits: 1
Flow
Control:
Disabled
EOL
Mode:
CR/LF
To run HyperTerminal, click on Start, click on Run, then type:
hypertrm
(use the exact spelling above). Then press Enter.
The HyperTerminal program then starts, and displays the
Connection Description dialog box as shown in Figure 4-5.
