FRS has said that this area is being explored.
My guess is we will see roll outs in later versions of SmartSDR v2.x to add what is possible.
Capability may not be completely level between clients (SmartSDR for Windows, SmartSDR for iOS, DogparkSDR for OSX and SmartSDR for M-model radios).
TBD and like things SDR charging with releases to add more is my best guess.
I am planning a parallel connection myself, as I want to do/control things I cannot expect FRS to integrate just for me.
BTW Ranko 4o3a has posted that he expects to start the integration of the Genius product control into SmartSDR in Q4 2017 in a post his Google+ group.
That would move things like Antenna Genius, Station Genius and Rotor Genius native SmartSDR control to later this year. Presumably the Power Genius Amp will be integrated into SmartSDR from the launch.
SmartSDR v 2.0 with SmartLink for remote operations, raises questions and options for those who want to control accessory equipment with serial interfaces. While control via the USB ports on the 6000 series radios is very useful, it is currently limited to band switching.
In anticipation of SmartSDR 2.0, I want to maintain full remote control of my equipment without the need for VPN or a computer running in the shack. Fortunately, I’ve found an inexpensive solution that will work without either. Specifically, I’ve installed and tested a USR-N540 (Jinan USR-IOT) four-port serial to Ethernet converter, which is accessible from the Internet or LAN, providing reliable control of my Green Heron RT-21, Elecraft KPA500 and other equipment with serial interfaces.
I use DDUTil, Elecraft software or DX Labs Suite, however any application that employs serial ports to control peripheral equipment can be run on a laptop, desktop or tablet, whether operating remote over the Internet or on your LAN. Again, this works for remote operations without VPN or a PC running in the shack.
The N540 does not have authentication for direct serial connections (it does have authentication for firmware configuration); consequently, for security I can shut down the device with a Digital Loggers Web Power Switch that is used to control power for all of my equipment.
The USR-N540 is available for about $72 with free shipping.
