As the afore mentioned document says, there are 2 versions of Pluto in the market. When talking about Pluto it seems to be worth to name the version which is addressed.
Recently got a new Pluto to work with Portsdown 4. The sticker on Pluto's blue Box says Rev.C, while the board inside says Rev.D, so call it Rev.C/D.
Used the Portsdown 4 set-up description as per wiki to configure Pluto from Portsdown. Verified on Portsdown menu 15 that both CPUs are activated and the frequency range extension has been introduced. Portsdown and Pluto worked as expected, except at 146 and 71 MHz no output was delivered from Pluto with Portsdown not going to transmit mode i.e. PTT signal was not raised.
G8GTZ wrote in an earlier thread that an additional input is necessary for Pluto Rev.D to achieve the frequency extension: input
fw_setenv compatible ad9364
pluto_reboot reset
That's it, all working.
Access to Pluto via network is easy: connect the OTP directly to the USB connector next to the blue LEDs and feed 5V to Pluto via the PWR USB connector. (Also checked the Y-USB cable sollution: did not function in my case with Rev.C/D)
Furthermore tested the Pluto Rev.C/D output being controlled from Portsdown 4 Pluto PWR setting. (M1)
