CDB5460A
2.1 Installation Procedure
1) Turn on the PC, running Windows 95^TM or lat-
er.
2) Insert the Installation Diskette #1 into the PC.
3) Select the Run option from the Start menu.
4) At the prompt, type: A:\SETUP.EXE <enter>.
5) The program will begin installation.
6) If it has not already been installed on the PC,
the user will be prompted to enter the directory
in which to install the CVI Run-Time En-
gine^TM. The Run-Time Engine^TM manages exe-
cutables created with Lab Windows/CVI^TM. If
the default directory is acceptable, select OK
and the Run-Time Engine^TM will be installed
there.
7) After the Run-Time Engine^TM is installed, the
user is prompted to enter the directory in which
to install the CDB5460A software. Select OK
to accept the default directory.
8) Once the program is installed, it can be run by
double-clicking on the EVAL5460A icon, or
through the Start menu.
Notes: The software is written to run with 640 x 480
resolution; however, it will work with 1024 x 768
resolution. If the user interface appears to be
small, the user might consider setting the
display settings to 640 x 480. (640x480 was
chosen to accommodate a variety of
computers).
2.2 Using the Software
Before launching the software, the user should set
up the CDB5460A evaluation board by using the
correct jumper and DIP switch settings as de-
scribed in Part I, and connect it to an open COM
port on the PC using the RS-232 serial cable. Once
the board is powered on, the user can start the soft-
ware package.
When the software is launched, the Start-Up win-
dow appears first (Figure 1). This window contains
information concerning the software’s title, revi-
sion number, copyright date, etc. At the top of the
screen is a menu bar which displays user options.
The menu bar item Menu is initially disabled to
prevent conflicts with other serial communications
devices, such as the mouse or a modem. After se-
lecting a COM port, the Menu item will become
available.
2.3 Selecting and Testing a COM Port
Upon start-up, the user is prompted to select the se-
rial communications port which will interface to
the CDB5460A board. To select the COM port,
pull down the Setup menu option, and select either
COM1 or COM2 (the DISK option is used for pre-
viously saved files, and is discussed later). Testing
the COM port to verify communication between
the PC and the evaluation board is not necessary,
but can help to troubleshoot some problems. The
procedure for testing the communication link fol-
lows.
1) Pull down the Setup menu option again, and se-
lect TEST RS-232.
2) When prompted, set DIP switch 1 (the leftmost
DIP switch) to the closed position, reset the
board, and press OK to perform the test.
3) If the test passes, set DIP switch 1 to the open
position, and reset the board to return to normal
operating mode.
4) If the test fails, check the serial port connec-
tions, power connections, jumpers, and DIP
switch settings on the board, and run the test
again from step 1.
Once the serial link is established between the PC
and the evaluation board, the user is ready to access
the internal registers of the CS5460A, collect data,
and perform analysis on the collected data.
