Phase 4: Connecting G59 to GSDR software via USB port


Connect the USB cable to G59 USB port. Plug the other end to any available USB port in your PC.
Connect 12V DC power supply.
Upon the power up, your PC will automatically recognize G59 hardware. Once the USB connection is established the green LED diode will light.


Download and install Power SDR (tm) Genesis software (GSDR).
During installation select G59 as your hardware. If you have previously used GSDR software with other Genesis hardware then go to Power SDR settings - General - Hardware Config - Radio Model - select Genesis G59.
The GSDR will automatically detect your G59 hardware and will establish USB connection. The USB button will light up green.


Checking the G59 and GSDR communication

Press the AF Preamp button.


With AF preamp "on", the voltage between pins SV1PA is 11.7V
(with AF preamp "off" the voltage is 0V).


Click on "Tun" button.


The voltage between pins of SV2PA should be around 11.7V.


Band selection check
Connect the input of frequency counter to resistor R19G.


Select 60m band, LOSC frequency 5.330MHz.


The frequency counter should read 5.330MHz.
Now select other bands as well. Again, the frequency counter should show the frequency exact or very close to LO frequency for selected band.


This completes testing of connectivity between G59 and GSDR software.



Troubleshooting

Communication between Genesis software and hardware is very much a straight forward procedure where default settings are loaded upon startup of GSDR. In case of no USB communication check the following:

- make sure to select G59 under Hardware Config

- under General - Genesis Config tab select Si570 address 170


Windows unable to detect G59 hardware

Symptom: green LED off, no USB connection.
There are a few possible reasons why Windows is unable to detect G59 hardware. Some of them are:

- USB cable not connected properly
- device not recognized by OS
- G59 micro controller not installed properly
- micro controller firmware not loaded properly
- G59 hardware assembly problem

The troubleshooting procedure is to determine which of above listed problems is causing lack of connectivity.

To check USB connectivity download and run Windows USB Viewer [usbview.exe].

If Windows is unable to detect or recognize G59 hardware, "NoDeviceConnected" status will show under the list of USB devices.

Properly detected and recognized G59 hardware will show up under USB view as
idProduct Genesis G59f, iManufacturer "YT7PWR".


Si570 "locked" on 56.320 MHz / 14.080 Mhz

Symptom: green LED on, USB connection present. However, regardless of which band is selected, under GSDR the Si570 appears to be "locked" on 56.320 MHz / 14.080 MHz.

Most likely, lack of communication between microprocessor and Si570 is caused by either missing / corrupt firmware or malfunctioning / incorrectly installed MOSFET TR1G and TR2G.
