Programming FTDI devices

Programming FT232R

This page describes how to program the FT232R chip for use in:

• Dávač 4 / USB2LPT + Dávač_3.0 or Dávač_3.3
• Rotár 4, Rotár 5 / USB2TTL
• USBIO
• HDKEYB

You need File:MProg3.5.zip (obsoleted by FT_Prog but always works).

Run MProg

MProg initial state

Disconnect all possible USB devices (can contain FTDI chip also). Connect your device with FT232R. Press Ctrl+N to create new programming template. Press Ctrl+C to scan. MProg responds in bottom box:

Number Of Blank Devices = 0
Number Of Programmed Devices = 1

Change:

• Device Type to FT232R
• USB VID/PID to Own VID & PID
• Vendor ID to A600
• Product ID by table bellow
• Manufacturer to OK1ZIA
• Product Description by table bellow

Device	Product ID	Product description
Davac4	E110	Davac 4.x
Rotar4	E112	Antenna rotator 4.x
USBIO	E113	USB GPIOs
HDKEYB	E114	HD44780 + Keyboard

Verify entered data, press Ctrl+V and save configuration to file. Pres Ctrl+P to programm.

In bottom box result appears:

Programmed Serial Number : FTVCZQUP

MProg device programmed

Replug the device. Run Control Panel and you'll see new device:

Repair wrong VID/PID

If you do a mistake and programm wrong Vendor/Product IDs to FT232R, you can try this recover procedure:

• Get real VID/PID from MProg or from Device Manager (Properties, Details, Hardware ID)
• Read section 4 of [1]
• Modify D2XX/CDM drivers to match device VID/PID. Leave only one device item like:

[Manufacturer]
%Ftdi%=FtdiHw,NTamd64 

[FtdiHw]
%USB\VID_A600&PID_E112.DeviceDesc%=FtdiBus.NT,USB\VID_A600&PID_E112 

[FtdiHw.NTamd64]
%USB\VID_A600&PID_E112.DeviceDesc%=FtdiBus.NTamd64,USB\VID_A600&PID_E112

[ControlFlags]
ExcludeFromSelect=*

• Scan devices in MProg, it should find the device
• Set proper values of VID/PID and programm these
• Without replug, Uninstall drivers in Device Manager
• Replug revice, it should have new VID/PID

Another way, works also on bricked chips
