communications port on the computer. Select the right port on the menu.
You can also check for communications by turning on or off the power of
an MCPA module using the RF ON switch on the front panel of the
module. The maximum available power reading on the menu should
change according to the number of powered-on MCPA modules (120W
for three modules, 80W for two modules, and 40W for one module).
If necessary, restart the software program to re-establish communications.
Fixing the ‘Run-time error’ problem
The reason you will get a ‘Run-time error’ is when choosing a comm port that
is not available. Verify that no other program is open and using the comm port
that the MCPA software is trying to use. If a ‘Run-time error’ message appears
every time you try to run the software, use the following procedure to fix the
problem:
1. Use the Windows Explorer to view the Windows directory.
2. Double-click on the ‘REGEDIT.EXE’ file. A Registry Editor will open.
3. Double-click on the directory ‘HKEY_CURRENT_USER’.
4. Double-click on the directory ‘SOFTWARE’.
5. Double-click on the directory ‘VB and VBA Program Settings’.
6. Double-click on the directory ‘Powerwave RD Testing’.
7. Double-click on the directory ‘System’.
8. Double-click on the ‘CommAlarmBoard’ file in the file panel.
9. A dialog box will open and a ‘1’ should be typed in the ‘value data’ entry
box. This refers to Comm Port 1. If a ‘1’ is already in the entry box, you
might want to try 2, 3 or 4.
10. Choose ‘OK’. The number ’1’ or the number you entered should be
displayed on the data column next to the CommAlarmBoard.
11. Close the Registry Editor.
12. Run the MCPA software again.
