CDB5461

2.1 Installation Procedure

1) Turn on the PC, running WindowsÂ®95 or

later.

2) Insert the installation CD into the PC and

open the cvidistkit.EVL5461 folder.

3) Run WindowsÂ® Installer executable. For

Windows 9x systems, run âinstmsi.exeâ; for

later systems, run âinstmsiw.exeâ.

4) Double-click âEVL5461.msiâ to begin instal-

lation.

5) Follow the installation directions on the

screen.

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 CVIÂ® Run-

Time Engine. The Run-Time Engine man-

ages executables created with Lab Win-

dowsÂ®/CVIÂ®. If the default directory is

acceptable, select OK and the Run-Time

EngineTM will be installed there.

7) After the Run-Time EngineTM is installed,

the user is prompted to enter the directory

in which to install the CDB5461 software.

Select OK to accept the default directory.

8) Once the program is installed, it can be run

by double-clicking on the EVL5461 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 CDB5461 evaluation board by using

the correct jumper and DIP switch settings as

described in Table 4, 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 software package.

When the software is launched, the Start-Up

window appears first (Figure 1). This window

contains information concerning the softwareâs

title, revision number, copyright date, etc. At

the top of the screen is a menu bar which dis-

plays 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 selecting 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 serial communications port which will inter-

face to the CDB5461 board. To select the

COM port, pull down the Setup menu option,

and select either COM1 or COM2 (the DISK

option is used for previously saved files, and is

discussed later). Testing the COM port to veri-

fy communication between the PC and the

evaluation board is not necessary, but can help

to troubleshoot some problems. The proce-

dure for testing the communication link fol-

lows.

1) Pull down the Setup menu option again,

and select TEST RS-232.

2) When prompted, set DIP switch 1 (the left-

most DIP switch) to the closed position, re-

set 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 con-

nections, 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
