  • Garmin Support Center is where you will find answers to frequently asked questions and resources to help with all of your Garmin products.
  • Thanks a lot Roberto. I have run/installed it etc, which all seemed fine. I restarted it and under the device manager the 'TUSB3410 EECode Ser' is still showing up with the little warning sign and saying that the drivers for this device are not installed (code 28), there are no compatible drivers for this device.

This is a new version without the need of an Arduino board.
Instead its based on a USB-UART Serial Adapter Module ( FT232RL in this example)

Last year I wanted to get the data out of my Diving Computer without buying $100 cable,
and I succeed doing it by using an Arduino board.
You can read about it here

I was getting lots of comments from people who didn’t succeed building this using other Arduino boards and I thought there must be a way to make it easier.
It just a half duplex (or ‘1 wire’ ) UART , so why it not build a converter from UART to ‘1 Wire’? It should’t be that complicated 🙂

Lets try to make it short

The diving computer has a connector with 2 connection points and a ground.
After poking with it for a ‘few’ hours (I drained all my computer battery and had only 6 dives with it!!) I found that:

  • A voltage on the Enable pin makes the diving computer enter the Data Transfer mode.
  • The Data pin is a bi-directional line, using UART for communication.
  • All the metal around the pins is ‘ground’.

The Suunto DM5 application is looking for a communication port named ‘Suunto USB Serial Port‘.

I used USB to UART Serial Adapter based on the FT232R chip.
Last time I modified the Arduino driver in order to change the device display name,
but after digging I found that Suunto use PID 0xF680 with VID 0x0403 which is the Vendor ID of FTDI chips.
That’s the reason I choose to use the FT232R.
I can still modify the driver, but I have a better option now which is to write to the FT232R eeprom memory and change its PID to 0xF680.
Windows think it’s the Suunto cable and install Suunto drivers with the name we want.
With this method I don’t need to disable the driver signing enforcement.

To modify the eeprom, I used MProg which is a utility from FTDI.

I first scanned for devices on the (Device->Scan), then read the current settings (Tools->Read and Parse), and then change the PID (Product ID) to F680 as you can see in the picture.
I flashed the new settings (Device->Program), uninstalled the current driver in the device manager (right click, Uninstall Device), and removed if from the USB port and then plugged it again.
I don’t know if it’s possible to program it multiple time so it might be irreversible.

Update: It might not be possible to change the PID of a cloned FTDI chip.
In this case, you can still use a modified driver (and disable windows driver signing enforcement), or just use other app like Subsurface which just asks for a COM port number

I can still sync the diving computer without doing this step, but I have to use other apps like ‘Subsurface’.

Because there is only one data line, it was not possible to connect both RX and TX of the UART adapter together as is.
I built a converter circuit with some transistor and resistors to make it ‘1 wire’ half duplex UART.

I used the 3.3V from the USB to UART module.
I also changed the jumper on the module to 3.3V (5V might hard the diving computer)

BOM:
– 1x USB-UART module (FT232RL)
– 2x 2N7000 NPN transistors
– 2x 1k resistors
– 1x 15k resistor
– Jumper cables (optional)
– Breadboard (optional)

All can be found in eBay or Aliexpress

If you are using a breadboard you almost don’t need to solder anything.
The only problematic pin is the ’33v’ pin that you have better a jumper cable soldered to.

The Ugly Side

I still didn’t find any novel way to connect with this connector.
I took a clamp and drilled holes in it, then pushed ‘pogo pins’ in such a way they will touch the connection points.
I need to think and make something more simple.

First prototype of a PCB version:

And. that’s it.
I can now sync my diving computer with my PC.

Have you ever had difficulty connecting your devices to your computer using a Prolific USB to Serial adapter? If yes you are lucky to find this page, it will give you all the information need to fix an unresponsive Serial driver adapter. You may have noticed a yellow exclamation mark hovering over or beside the USB to Serial Driver when searching your Device Manager and if you have we can all agree that it signifies a prevailing problem.

Overview of the Error

If you are not able to connect your device to your PC using a USB to Serial adapter it may be that

  • The USB driver is outdated
  • The USB Driver is missing
  • Or even a corrupted driver

While you can't be so sure what the exact problem is there are solutions you can adopt to fix the issue once and for all. Read on to find quick fixes to resolve the problem.

1# Fix Prolific USB to Serial Driver not Working

Solution: Roll your Prolific USB to Serial Driver back to an older version

Updating your drivers often work wonders for your system because it makes sure that it runs on the latest features that guarantee maximum functionality. Unfortunately updating your drivers can cause this kind of error especially if your latest update does not work too well with your hardware. Once you upgrade your PC to the latest Windows version your Prolific USB to Serial Driver also updates to the latest driver software and if the driver is not compatible with your Hardware issues may arise. To correct the error, you will have to download the driver again by following these steps.

  • Right-click on your PC Start button and open Device Manager
  • Double click LPT and COM ports then locate the Prolific USB to Serial Driver and right-click it so you can select Update Driver
  • For driver software click My computer
  • From My computer select 'Let me pick from a list of drivers available'
  • Choose an older version from the list then click Next
  • The driver you selected will be installed automatically
  • Once it has been downloaded reconnect the driver to see if it works.

2# Fix Prolific USB to Serial Driver 'Coder 10'

Driver issues reveal themselves in so many ways or through messages such as

  • This device will not start (Code 10)
  • There is no driver installed in this device
  • The driver was not successfully installed

A code 10 error may arise because the chip you are using is not an original one. If you are using a fake, the manufacturer has a way of disabling it due to copy write infringement and the copy write takes effect once you download a recent update. To protect your PC from getting this code, you will have to make sure that your Windows 10 never updates a driver without approval. Updates come in the form of 64 bit and 32-bit drivers. Below we will show you how to work your way around the problem.

Window 64 bit Fix

To fix Windows 64 bit OS including Prolific USB to Serial Adapter, follow through these steps.

  • Download 'PL2303_64bit_Installer.exe and Save
  • Remove every USB to Serial adapter from your PC and double click the 'PL2303_64bit_installer.exe
  • Follow the prompt by plugging in one USB to Serial adapter the click on Continue
  • Reboot your PC to get Windows up and running

If you have followed these process through and you still see the same error go to your device manager

  • Open the control panel and navigate to Device Manager
  • From your control panel navigate to the System category and click the Hardware tab
  • Scroll to the LPT/COM port and double click Prolific USB to Serial Comm Port
  • Click Drivers in the Properties section
  • The Driver you choose should read '3.3.2.102 with an appropriate date attached
  • If the date is wrong then it means the wrong driver was installed
  • Unplug the Serial adapter and run the steps again to install the correct driver
Driver

Window 32-bit

For Windows 32-bit OS systems follow these steps

  • You will have to download the 'PL-2303_Driver_Installer.exe and save from Microsoft download link
  • Run the program and eradicate the driver if you can
  • Run the installer once more to install a correct driver
