Hello,
Some SDS100 users want to know about the mysterious USB1 port. Why does the SDS100 have both a Mini-USB and a Micro-USB port? It was obvious to me as to one possible use.
I do not expect any comment from UPMan until any future feature is released. I was involved in product development several times where included hardware was never used or years went by before it was supported. I do not work for Uniden, so any comment I make is speculation and not a commitment by Uniden to provide any additional features. I put this message in the tavern since it is wild speculation. It maybe a dead end.
When I attached a USB cable to USB1, it enumerates as a serial port. There is output indicating the SDS-100 Sub-processor. If you type a lower-case ASCII charactor from a limited set (dhlmoqrwz), several lines of formatted ASCII numbers are sent from the scanner. This looks like engineering debugging output rather than a customer feature.
The sub-processor appears to be a NXP LPC4370. This is an interesting chip with one ARM Cortex-M4F processor and two ARM Cortex-M0 co-processors. It includes a 80MSPS 12 bit ADC. I speculate this chip is involved in digitizing the IF and demodulation.
A dedicated USB port would be needed by the sub-processor for high data rates, like an IQ output. The IQ port on the AOR and Icom radios are a separate USB port from the USB port used to control the radio. That is why the two USB ports peaked my interest.
I do not think the future feature will turn the SDS-100 into a RTL-SDR. A Uniden provided driver on the PC will likely be needed and the functionality may be limited. We will have to wait and see if anything using the mysterious USB1 port is officially released.
