MyGeiger ver.1.00

Required hardware:
1. MyGeiger kit
2. USB-TTL adapter (CP2102 / FTDI FT232 5V/3.3V / PL2303HX)
3. 4pcs of jumper wires female to female
4. USB cable
5. Computer with internet

Connect USB-TTL adapter to the computer and check in Windows control panel you have new virtual com port. Com port number is random and depend how many other com ports you have on your computer. Now disconnect the USB-TTL.
Use 4 jumper wires to connect MyGeiger to USB-TTL adapter. Take note, there is 4 pins you need to use: RX, TX, 5V, GND.
Power line 5V do not have reverse polarity protection, that's why I recommend you to check polarity twice before connecting the USB adapter to the computer!

Connect USB-TTL to the computer. The kit should start working, you do not need to use power switch button. If you are using Radiation Logger navigate to File --> Settings. Press "Get Available Ports", choose your com port where USB-TTL connected, set 2400 baud rate and press "Test Connection" You may wait up to 30 seconds before connection confirmation. After that navigate to File--> settings and enter your user name and password. Set conversion factor for your GM Tube and press "Start Log" The application will upload average CPM value to radmon every minute.

MyGeiger ver.2.00

Required hardware:
1. MyGeiger kit
2. USB cable
4. Computer with internet

The second edition do not require to add any TTL adapters because FT232RL IC is already installed on the PCB. You need to install the drivers and just connect the USB cable.
