[WT-support] Icom IC-910 Settings

Known good settings for Icom IC-910


I am using a serial connection from the transceiver to an RS232 9 pin COM
port on a desktop PC (COM4 in my case, on an additional Serial card). There
are some electronics in the 9-pin plug, which may require power, which is
probably derived from the DTR line.


Settings for an IC-910H are as follows:

In the radio menu -

CI-Addr = 60

CI-baud  = 19200

CI-trn = on


In WinTest -

IC-910 set as the current radio type.

Neither "Don't Poll" nor "Use CI-V Transceive" should be selected.

Choose IC-910 Default Settings.

Port properties: 19200 - 8 - None - 1

DTR Pin 4 = Always ON

RTS Pin 7 = Always OFF


The Sub VFO frequency does not show in WinTest and it's not possible to
right-click the band map and set a spot to the Sub VFO.


I don't think much of the IC-910 as a serious VHF radio, although I bought
it with that intention.

Glad you got it to work, but please document what settings you are using in
the Icom menus for:


CI-V Address:

CI-V Baud rate:

CI-V Transceive:


Also, are you using a USB-to-Serial adapter?  What type?  What does it say
in the Windows Device Manager for driver type?  Some USB-to-Serial adapters
need to get power from the DTR or RTS PIN (it seems).  Or is it a real 9-pin
serial port on a desktop PC?

Thanks to all for the help with this issue.

Yes, Bob, neither polling nor CI-V Transceive are selected, but, as Martin
has suggested, I had to select DTR On.

No, there's no logic to it but it's working now!


Thanks and 73

I use a 910 with Wintest at G6Uw snd I think one of DTR and RTS has to be
on. Not sure which but may have time to look tmw.
