First. The receiver has a 4 contact jack.
Tip: RX from receiver.
Ring 1: Ground
Ring2: TX from receiver
Sleeve: Ground.
Hitools is not for Broadcom chipsets. And the copies I found are loaded with viruses or someone charges.
I found the SPI NOR flash chip.
I finally did probe the com port jack with my oscilloscope.
Ring 2 gives a complex set of 5 data bursts when plugging the reciever in. Promising.
While backing up my dish positioner to a file I got no response. Did a loopback test on the FTDI. TX is dead.
Waiting on 2 replacements. Win 11 tried to obsolete the Prolific FTDI cable and had to force older drivers.
Ones coming say Win 11 plays nice.
Don't feel bad. Edision.gr pointed me to the wrong cable too. I asked for tips for a recovery process. They are clueless and sent me on an endless fox chase with the image developers.
I don't even have a clue how many developers even have electronics experience.
It may come that I need to pull the nor flash chip and flash dump/compare it.
Writing bios firmware in a stand alone flash programmer saves a lot of bricked motherboards in my little shop.
But since there is a nice data burst, things look better. Maybe. Right??
