I am using a 6500 and ALS-1306 remotely with Maestro. I have no parallel port so I control band selection using a DLI remote relay to generate the A-B-C-D data. Then I control the relay with the iPhone IOS app supplied by DLI to select the band. Band selection is not automatic, but I do have positive control over band selection. I also power the Flex on and off via one set of contacts in the DLI DIN relay. http://www.digital-loggers.com/din.html. I got mine at Amazon.
