Why do i get an error window when i press read on the program for the radio????


If the interface cable has a serial port connector, and you need to use a USB --> Serial Port adapter to connect to your computer; it may be the source of the problem. The cheaper USB --> Serial adapters have issues with timings that the serial port protocols rely on. You may have luck by reducing the speed of the serial port to something like 19200, 14400, 9600, 4800 or even as low as 2400 baud. Make sure that the adapter name (COM1, AUX1, COM2, AUX2 , etc.) is the SAME one you're telling the program to use to access the radio's memory and the port's parity, number of stop bits and error checking type match the program.

Additionally, different radio manufacturers use different methods to set the radio's memory up to be read and / or written. Make sure the radio is ready to be read and the program is trying to read - not write (and vice versa).

If you're still having issues, please reply and provide the radio brand and model, interface cables and adapters, and program software and computer Operating System.

I cant figure out how to connect my jornada to my pc.. can you help?


Hi,

Are you connecting from dock to USB on computer, or serial to USB via a USB-serial adapter? UBS-serial adapters are notorious for not recognizing attached serial hardware. What kind of errors are the Jornada and the computer throwing? Can you give any specific error numbers?

If you are connecting using the serial cable to a serial port on your computer you need to make sure that the Jornada is trying to connect to the correct COM port (and that the computer is allowing connections through the correct COM port). Do this by:
1. Open Device Manager (R-Click on My Computer - Properties - Hardware - Device Manager)
2. Expand the "Ports (COM)" plus sign
3. Beside each COM port's name it will say (COM#) - the # tells you which port the COM is
4. Go into ActiveSync and open Connection Settings (in the File menu in ActiveSync 4.5 - the latest)
5. Make sure all the check boxes are checked and that the correct number COM port is selected in the drop down menu under "Allow connections to one of the following:"
6. Connect your Jornada via the serial cable, make sure the Jornada is on and connected to power cable (I have had more success with the power on - may or may not affect your problem)
7. Click the "Connect..." button in ActiveSync. The Jornada should be detected.

If your computer has an infrared port you could try that, I have had a lot of success with infrared connections with my Jornada. Also, try installing ActiveSync on another computer that has a serial port and try connecting the Jornada to that computer. It may be a problem with your computer.

An older version of ActiveSync should not make a difference. The facilities are the same, just slightly rearranged.



Please post your feedback and Vote if the problem resolved as per your satisfaction.

My older hi-pro box will not work with my serial to USB adapter. It keeps saying it cannot find it on com 1,2,3,4. In the device settings it says the hipro is on port 2 and the serial/USB bridge is on port...


I just set up a serial Hi-Pro box for one of my customers on their new laptop. According to Beltone, the only usb adapter that will work with the Hi-Pro (or at least the only one they have gotten to work) is a Belkin F5U409. I know some usb serial adapters don't use true serial communications if that makes any sense, so there isn't really a baud rate. They kind of just send out the communication in bursts...

In any case, ive only tried with the belkin adapter and that worked fine with no problems. The other point here is that your Hi-Pro and Adapter are on different com ports... This is odd, the hi-pro should be on the serial adpater's com port. Also the software i was using - Noah, with a beltone module for programming hearing aids.. only looked on com ports 1-3. The computer put the serial adapter on com 8 - which would not do. I checked for available com ports and saw that 2 was unused. I set the adapter to 2 and was able to set up the program normally.

I did this on Windows 7 Professional 32 Bit. The procedure for selecting the com port is the same on earlier versions of windows.

First, open device manager, open the list titled "Ports (COM and LPT)". You should see your serial adapter in there. Double click it. In the window that opens click the "ports" tab, and hit the button labeled "Advanced" In the window that opens there will be a drop down list to select a com port. Select the desired com port and hit ok. That should fix it.

"Camera not connected." -- Serial connection


The "Camera not connected" error message indicates a communications problem in the serial port connection between the camera and the computer. Simply put, the computer cannot find the camera it is being asked to connect with. Whenever an external device (digital camera, scanner, Palm Pilot, etc.) is connected to a computer through its serial port, a communications error is possible. There is usually no single "most likely" reason for the conflict -- it could be a hardware issue as easily as it could be a software issue.
