7300 not connecting to Mac

1

I’ve got an IC-7300 USB connection to Mac Mini. I’ve tried connecting to a USB hub, as well as directly into the back of the Mac Mini. I’ve got the 7300 setup exactly as described in the manual, but wfview is still not seeing the radio. The 7300 appears when running “system_profiler SPUSBDataType” (right now it is plugged into a USB hub):

CP2102 USB to UART Bridge Controller:
Product ID: 0xea60
Vendor ID: 0x10c4 (Silicon Laboratories, Inc.)
Version: 1.00
Serial Number: IC-7300 02038461
Speed: Up to 12 Mb/sec
Manufacturer: Silicon Labs
Location ID: 0x14141000 / 12
Current Available (mA): 500
Current Required (mA): 100
Extra Operating Current (mA): 0

Looking for any suggestions on how to connect.

Check the settings on the radio, in particular those related to baud rate, “remote link”, and CI-V Transceive.

Here is a how-to with radio screenshots:

Thanks for sharing, your presentation was the best collection of steps I’ve seen so far. Alas, I had all of those settings already configured as described, so I remain baffled. I may try a factory reset on the radio, I saw that mentioned elsewhere. Thanks for the suggestion.

Paul,

Send us the logfile, there may be good clues there.

Here’s what I got from the log file… there were a ton of “device not open” lines after the one shown here.

I see:

2022-03-15 17:46:13.114 INF serial: Could not open serial port “/dev/tty.SLAB_USBtoUART” , please restart.

Did you try to run as root too?

If that works, you have no rights to talk to the device. (yet). In linux you can fix this by adding the user to dialout. On a mac I say “it always works” – just kidding; on a mac no idea. I don’t have that in my home.

What do you have selected under Settings/Serial Device? Auto-detection of the rig serial port only works on Linux so you must manually select the port from the combobox on Mac/Windows.

Serial device was set to auto. What syntax would I use to enter the port manually? The field defaults to /dev/device

Here is the USB port info:

Hi Paul.

Which version of MacOS are you using? V10.9 (Mavericks) introduced direct support for the Silicon Labs VCP but if you are using an older version (or if yours isn’t detected for some reason), you will need to install the driver from https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers

The USB serial port should then appear in the Serial: dropdown/combobox. There is no way to manually enter a device as it wouldn’t work if it wasn’t recognised as a valid serial port anyway!
