New page

=Davac 4.1 OK1ZIA=

Davac 4.1 is updated version of [[Davac4.0|Davac 4.0]] designed in 2008.

==News==
* IRLML2246 instead of IRF7220
* Silkscreen cleanup
* Values on silkscreen
* Jack holes are 2 mm
* Guard ring connected to GND
* Manufacturing data for [http://jlcpcb.com jlcpcb.com] included

==Errata==
* Optocouplers are TLP627, not PC817 (error during convert Eagle -> KiCad)
* Headphones have GND connected to hot and vice versa. I recommend skip REL2 and connect radio to headphones directly

If you have extra pcs and want to help other Tucnak users, let me know, I will announce here.

==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===
Use [http://rtr.ca/ft232r/ ft232r_prog].

Usage:
# ft232r_prog --new-vid 0xa600 --new-pid 0xe110 --manufacturer OK1ZIA --product 'Davac 4.0'
...
Rewriting eeprom with new contents.

Now replug the device

# lsusb
...
Bus 002 Device 007: ID a600:e110 Asix OK1ZIA Davac 4.x
#

In the case of mistake, use --old-vid and --old-pid. AFAIK this can be used also to fix fake FT232 bricked by Windows FTDI drivers.

===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.

Choose '''WinUSB''' and press '''Install Driver'''.
