Ondra OK1CDJ has made PCBs and offers it at [https://www.hamshop.cz/pcb-c7/pcb-davac4-ok1zia-i358/ www.hamshop.cz]. Many TNX!

===Errata===
* Jack holes are slightly smaller - user Dremmel milling cutter
* Parts values would be shown - use schematic

==Program the FT232R==
As default, the FT232R acts as serial port. But Tucnak uses Libftdi to access it in bitbang mode. Default VID:PID must be changed to distinguish Davac from other USB serial ports.

===Linux===
I'm pretty sure you can use [http://rtr.ca/ft232r/ ft232r_prog]. But I have no experiences with it. If you try it, please let me (OK1ZIA) know, I will update this information.

===Windows===
[[Image:Davac4.png|thumb|none|666px|MProg with loaded Davac4.ept]]
Under Windows, use [http://tucnak.nagano.cz/download.php#mprog MProg]. Download [[File:Davac4.ept]] and open it in MProg. Note on Windows XP you need [https://www.ftdichip.com/Drivers/D2XX.htm D2XX drivers]; on newer versions they are installed automatically.

'''Unplug all other FTDI devices''' and press the '''Program All Existing Devices''' button.

==Install USB drivers==
===Linux===
You have nothing to do, It will work automatically. Only on specific distributions you may have to set permissions to USB device, which is normally done by udev script.

===Windows===

[[Image:Zadig.png|thumb|none|589px|Zadig with Davac4]]
Under Windows 7 or newer, use [http://tucnak.nagano.cz/download.php#zadig Zadig]. On XP use 2.2.

Click Options, List All Devices.

Keep '''libusbK''' and press '''Install Driver'''.
