Hello everyone!
I am trying to figure out what I am doing wrong or not doing on this little project.
I have a 596C HD and I am tyring to make an USB cable so I can update the unit firmware. Paying $50 to buy the AS PC3 just to update the firmware seems to me a big waste of money. I guess I'm just used to be able to update firmware easily with a supplied USB cable or port on all my other electronic gadgets.
I got this diagram from a very helpful member on this forum but so far it is not working for me.
This is what I have done:
1) I made a USB cable connecting to the com connector of my unit.
The pinout I am using is:
2) Connected to 12V power supply to power up the unit.
3) Installed humminbirdPC on my Windows 7 (64bit) PC.
After making the connections to my PC the Humminbird PC has so far been unable to detect my 596c.
One observation that is quite strange, my PC while not detecting the 596C connecting to it's USB port, it makes the usb connect tone immediately followed by the USB disconnect tone and on the desktop an error msg will popup saying that there was an error installing driver or usb malfunction.
I have tried different sequences but so far nothing has worked.
Anyone here knows what I am doing wrong or what I am missing?
Thanks in advance for any help!
