This is archive of Davac 4.0. It was superseded by Davac 4.1
Davac 4.0 OK1ZIA
Davac 4 was succesfully built by OK1USW, OK1UGE and OK2JTB.
Note: 600 DPI have images in Full resolution, MediaWiki uses thumbnails.
Ondra OK1CDJ has made PCBs and offers it at www.hamshop.cz. Many TNX!
- 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.
I'm pretty sure you can use ft232r_prog. But I have no experiences with it. If you try it, please let me (OK1ZIA) know, I will update this information.
Unplug all other FTDI devices and press the Program All Existing Devices button.
Install USB drivers
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.
Under Windows 7 or newer, use Zadig. On XP use 2.2.
Click Options, List All Devices.
Keep libusbK and press Install Driver.
SMT variant by OK2JTB
All data: File:Davac4-ok2jtb.zip
If you want this PCB, try to ask OK1WMR.
Made by OK1UDC(SK) & OK1UGE
Note OK1ZIA: better use USB-B type connector
Combined Davac4 and contest machine RPi
Guys from OK1RPL made this amazing compact contest solution.
