EncoderCAT  - FT245RL  USB device configuration

The EncoderCAT PCB contains an FT245RL  USB interface device   (made by FTDI)

FT_Prog is FTDI's configuration utility for the FT245RL USB device.

xCatSetup.exe bundles FT_Prog and on completion offers to install it.  

This is version  It works fine on Windows 10.

The latest version on the FTDI website crashes for me on device scanning.
A quick Google search reveals that I am not alone here.  ... so use  !!

USB device drivers

The installation needs:

xCatSetup.exe is the xCAT installer. It also has the following functions:

Therefore please run xCatSetup.exe before carrying out USB device configuration

USB serial port driver

Connect EncoderCAT's micro USB connector to a PC USB port.

The familiar balloon popup window appears at screen bottom right. The identification text will be

'USB serial port found' (or similar) in a new gateway.

The driver may then install automatically with no further user action.

If not, then the windows below may appear:

Windows will offer to search Windows updates for the driver - this usually works ok after several seconds


The screens below require answers:'Yes this time only'   and then 'Install the software automatically'

If no driver is found, then follow the on screen instructions (back button may be needed) to locate

the FTDI_drivers folder on the EncoderCAT installer source device or C:\Program files (x86)\hbradios\xcat\FTDI_drivers

and then click Next to find and load the driver from the CD.

Sometimes, for reasons known to Microsoft, Windows seems to lose interest in a failed USB device

driver installation and no longer presents installation options.

If this happens, then you need to locate the device in Device Manager (or Hardware Manager).

(use Start button > control panel > System > Device or Hardware manager )

The device will be under USB devices or Other devices.
It will have an exclamation mark against it. Right click, select properties and then Update driver.

Point the driver location Browser to the FTDI_drivers folder on the xCAT installation media.

or C:\Program files (x86)\hbradios\xcat\FTDI_drivers.

ftd2xx.dll   (supplied by FTDI, the USB device manufacturer)

The correct version is in the i386 subfolder of the following download from FTDI:


However, you do not need to download it because:

ftd2xx.dll is installed when xCATSetup.exe is run.  

Its installed location is C:\Windows\system32  on a 32bit machine

                          and C:\Windows\sysWOW64 on a 64 bit machine  

FT_Prog needs ftd2xx.dll but the FT_Prog installer appears not to install it.

However, FT_Prog uses the ftd2xx.dll installed by xCatSetup.exe

FT_Prog    (supplied by FTDI, the USB device manufacturer)

The FT_Prog installer, FT_Prog_v2.8.2.0 Installer.exe is installed and optionally run by

xCatSetup.exe as described above.

It can also be downloaded from:


FT_Prog user manual is installed by xCatSetup.exe as described above.

It can also be downloaded from:


Actions required are therefore:


USB devices have an EEPROM containing an identifying text string and other configuration information.

This text pops up on the PC screen when the device is first connected.

Raymon is programmed to look for FT245R devices but only recognises them if 'EncoderCAT' appears

somewhere in the text string. ('EncoderCAT'  is not case sensitive here)

So the first task is to modify the EEPROM data.

This is done with FT_Prog.


If you make changes to the FT245RL EEPROM with FT_Prog and then rerun FT_Prog to view the settings, then you will see confirmation of your changes.

However, xCAT will not see these changes until the FT245RL device is powered down and up again.

Powering down the module does not achieve this!  The FT245RL is always USB powered and so you must disconnect and reconnect the USB cable.

This is likely to be a Windows issue. FTDI's FT_Prog communicates with the FT245RL using the same FTDI dll  (ftd2xx.dll).

Switch on the Gateway module and connect by USB to the PC

- You should see a pop up box informing you that an FT245R device has been found.

Run FT_Prog and click Menu | Device | Scan and Parse

You will see a tree control on the left and a summary configuration on the right.

The images below were obtained from an FT245R device that had already been configured.

As such, they serve as guide for what you should configure.

Please note: If you have other USB devices attached to your PC that use FTDI devices, then they will also be shown.

Initially the tree root is highlighted with a configuration summary showing on the right.

Click to select Chip details.   FT245R  - no action required

Click to select USB Device Descriptor:   - no change needed

Click to select USB Config Descriptor:   -  Set as shown

Click to select USB String Descriptor:  

The Product Description string must contain the letters: ENCAT or encat (case insensitive).

Auto Generate SerialNo: is unchecked in order to allow entry of a EncoderCAT  serial number.

The serial number can be anything you wish, eg: EN0002

(Note that some of the screen images in this document show an earlier shorter serial number format.)

Please note that if you return to make a change, then Auto-generate serial no will be checked.

You must uncheck this, otherwise your serial number will be changed.

Click to select: Hardware Specific:  These are left unchecked.

Now click the  program button OR  menu | Devices | Program

Then click Program on the confirmation window and the device will be programmed.

Terminate FTProg

Unplug the USB cable

Wait 3 seconds.

Reconnect the USB cable

Start xCAT

xCAT's status bar should show:      

And then, if  EncoderCAT code is running:
