I've spent the last hour and a half attempting to assist another ham via a Teamviewer session get Commander working the his TS-480HX. He has a RT Systems USB-63 cable and the RT Systems driver installed. (Viewing this via Windows Device Manager COM ports.)
RT USB-63:?
His rig is likely set to 9600 bps (Kenwood default), but I'm working with him to confirm.
In Commander I selected KENWOOD and the port is 9600 8 N 1 with DTS and RTS are both set to On. The Port# is set to COM5. (Port appears/disappears in Device Manager Ports when he plugs/unplugs the cable and port is set to 9600/8/N/1.)
System notes:
1) Has a K5IFNZ "Easy Digi" device attached to his laptop and this is plugged into the DIN/Data port on the TS-480.
2) He has an RTL-SDR dongle which is connected to the via an IF connection inside the TS-480.
3) Also runs HDSDR software as a panadapter. All of this appears to be working OK. HOWEVER, this software was NOT running when we tried to connect to Commander, but all of the cables for Easy Digi and IF cable are still plugged into the rig.
4) Also using a non-powered USB 4-port hub. Ports connected to the USB-63, IF wire, and Easy Digi.
We did attempt to connect the TS-480 using the USB-63 plugged directly into the laptop (no USB hub). We did power down the rig and rebooted the computer, etc.
Since I don't own a Kenwood rig, I'm wondering if there is something else I'm missing. This may include needing to disconnect the other devices from the rig.
