BC785D: Uniden BC785D Serial Port Problem

[AA5ST]

I have a Uniden Bearcat BC785D and using ProScan. My problem is when I set the com-port to com 1 (It a real com-port on the computer) and I hit the Auto-Detect button it sees the scanner on com 1, but when I try to control or download/upload it says Scanner Must Be Communicating. I’m running Windows 7 and the com-port works fine on my BCDx96XT scanners and using an Straight Through Serial Cable. Any help appreciated. See Pictures Below.

Try setting the port to None then click on Set then Auto Detect again.

Ok I set the com-port to None and click Set then click Auto-Detect button and it said com 1 Available.

Set it back to com-port 1 and click Set then click Auto-Detect button and it said BC785D but still nothing. Thanks

Does the 785D need to be in "PC CONTROL" mode to be used with Proscan?

That was my thought. I know the BC780XLT had to be put in PC mode.

The scanner is set to 115200 and the software is set to 19200 it will never talk like that.

 

[ProScan]

Ok I set the com-port to None and click Set then click Auto-Detect button and it said com 1 Available.

Set it back to com-port 1 and click Set then click Auto-Detect button and it said BC785D but still nothing. Thanks

When it said "Available", did the scanner show up in the next column? If no then go to the Menu - System Options - PC Control and select 19200

 

[AA5ST]

No it did not but yes the scanner is set to 19200 under PC Control I have tried all setting under PC Control to the other speeds making sure ProScan to match the same speed. I have even set Windows 7 Device Manager under the Ports to match com 1 and the scanner and ProScan port speed, but still no luck. Lost in the Twilight Zone, thanks for all the help.

I have no trouble with PROSCAN and my 785D you are using a NULL CABLE or a NULL MODEM correct?

 

[AA5ST]

Straight Through Serial Cable no null modem.

Edit.

Ok Thanks will give it a try. Got a Null Modem Adapter coming from Amazon.

Don't use a null modem cable or adapter. Those are only needed with rear ports that doubles as a GPS port such as the BCD996P2 or other DMA models.

or if using the cloning mode on the older units, right?

Correct.

If the same "Straight Through serial cable" works with the BCD996XT rear port then it's not a straight cable and a null modem will work with that.

 

[buddrousa]

Now I remember why I have those I have both type cables.

That's what I was thinking, he thought it was a straight thru cable...but it's actually not.

If one doesn't...the other will!
