Yes but the instructions are for the IC7300 didn’t work. I searched this forum for connection issues with the IC7100 and found that you have to manually set the CIV address to 88 and the baud rate to 19200. It will then show radio connected.
So this description below works…
Press “Connect to Radio” (bottom of the window). If successful, the radio model number should appear in the window title bar and the lower-right corner of the window. Once working, press “Save Settings” (bottom left of the window).
However I have no control of the radio. I’m a bit perplexed - my IC7100 might need a firmware update…using wfview v1.62.
Hi David, although it is for the IC7300, the majority is the same for the IC7100.
Where did you see that you need to manually set the CI-V address? This is completely incorrect!
You should enable CI-V transceive on the radio and leave CI-V to auto in wfview (this is the case for every radio that supports CI-V transceive). The baud rate in wfview MUST also match whatever is set in the radio. Unfortunately, in the IC7100 Icom decided to only allow a half-duplex serial connection (even for USB serial) which can cause issues with CI-V collisions (missed commands) reducing the baud rate can alleviate this problem though.
If you are planning to use wfview as a server, you also need to configure the Server audio devices (within Server tab) as currently they are not set correctly.
I have some limited progress. I have set CIV to auto and baud rate to 9600. WFView no longer recognises the radio as an IC7100 (waterfall spectrum is displayed, and signal meter does not work) but the VFO dial works - it doesn’t sync with the IC7100 frequency when powered on from the radio. I also can power down the radio but it will not power up. It seems like it needs to know its an IC7100 to get the correct command set. Bottom RHS of screen shows radio as NONE.
On the weekend I resolved the issue. After trying a couple of different laptops I went back to the Icom drivers page for Windows. When you download it there are 2 options. Initially I chose the Win10 version. This does not work. You need to use the version contained in the folder Win7_81_10. I assume this might be to do with my IC7100 being an older model (using firmware 1.4). Anyway it’s all working now. Thanks for everyone’s help. 73s
The IC-7100 is finicky indeed. Just updated its firmware and it was stuck in the bootloader until I unplugged everything unnecessary from the main unit. Btw, even the latest firmware updater from Icom (Release E5) doesn’t update any of the components beyond 1.11, so I don’t know what firmware 1.4 you’re talking about. I do note that 1.41 is current firmware for the IC-9700, however.
With firmware Release E5 installed I’m able to use the Win10 serial driver with Wfview and it works fine. Of course, being limited to 19200 baud means no waterfall; but Wfview controlled the rig just fine.
Hi Sam, the IC-7100 doesn’t provide a waterfall anyway…
It is also the only USB capable Icom that we have found which only provides half-duplex serial connectivity (even over USB). We have verified this with the circuit diagram, RX/TX are connected together. This makes the IC-7100 VERY picky especially when using a fairly high poll-rate in wfview, as commands from the virtual serial port can easily ‘stomp’ on replies from the radio and cause a collision.
I am currently working on various ways to mitigate this as part of my overhaul of the entire rig communications code, and results are fairly promising at the moment, so watch this space…
