How do I get that software
OK buddy let's give it a shot.
First and foremost make sure you have and installed the serial drivers located at the bottom of the page for the BCD436 from here:
BCD436HP < UnidenMan4 < TWiki
When the serial driver software is installed go to your device manager on the computer and find what com port your scanner is now on. Remember that as you will need it in a future step.
Next go to this link for the newest version of Scanner screen:
https://docs.google.com/file/d/0B_Jndzk4GdzJNHdDQWJNR0hqUFU/edit?pli=1
Go to the very first line where it shows:
ScannerScreen / ScannerScreen.exe Executable File 2.8 MB with a drop down box.
Select the drop down box and select download.
Once you have it downloaded and on the PC open the software.
Once you have the Scanner Screen opened plug your scanner in and select the com port setting from above I told you to remember. Once you select the com port select connect to computer. When it is connected you will see "Scanner busy" on the Software screen. Make sure you have the Text To Speech check box marked and you should hear it say the channel that livens up with transmission. Example> Sheriff> Dispatch 1.
Remember that you will need to turn the scanner off then back on before plugging into the USB and using the serial mode. There is a flaw of some sort that does not allow full operation of serial mode on some third party software. This is the work around for it for now.
