FIRMWARE 2.28

[LA4ESA]

Hi.
I have just upgraded both RRC units with the new Firmware, 2.28.
A ham freind told me that it is important to set COM2 mode to: "Logical paralell with COM 0" to read HRD correctcly into my Kenwood TS-480. When i do so, and push the "Submit" button and the the "apply changes", the RRC control restart.
When i get back to the serial setting, the COM2 mode has changed to "inactive"
I have tried several times and the same happends every time. Any suggest?

If you use TS-480 with control panel in "radio mode"= 5 the selection "Logical paralell with COM 0" is not allowed and is automatically deselected, thats what you see. The only time  "Logical paralell with COM 0" should be active is if you connect for example HRD to COM 2 at control-RRC and the radio to the TTL port at the Radio-RRC. This is mostly used with ICOM CI-V and FT-8x7, never with TS-480.

ok, but what kind of connection do you suggest for my TS-480? I have done this: TTL connection at the radio RRC and of course to the COM2 at the radio end to transfer the Req. to the HRD at the control RRC.
in the control end:  HRD to the COM2 at the controll RRC. The reason for why i have done this, is through your's explanation's from the very beginning og my configuration og my RRC system.

Do you use both Control panel and HRD ?

I use RRC in both ends and HRD at the control end. RRC are connencted like this:
By following your instructions from the link to "Kenwood TS-480"
At the radio end i have also connected the RS232 cabel fra COM port on radio to COM2 at RRC.
At the control end i have connected the RRC 232/USB with FTDI chip from COM2 at the RRC control to the USB port at the PC.
After switch the radio on, i can now open HRD and connect the radio to it. The HRD now read the freq.
I do not understand your allegation that TS-480 not should be connected to the TTL port at radio end, connection to the TTL port at radio end are used in your instruction, mentioned above.
Do i misunderstand something here?

OK

I couldn't even think that anyone will use HRD instead of the remote control panel when controlling TS-480, but then you do not use radio mode 5 either as I wrote. When controlling like you do it's the instructions for Kenwood in general which is applicable.

It's clear for me now, there have been some misunderstanding here. I am NOT using the HRD to control my radio.
I have connected the HamRadioDeluxe only for one simple reason, thats to read the freq. into the logging software.
I use only the RRC units to control the Kenwood TS-480. But, anyway, the radio are now working well and so are the HRD.
