RCS-4 Antenna Switch Replacement - WA4MCM Remote Switch
|
I talked with Don the owner of WA4MCM and he is now shipping a version of his remote antenna switch that communicates via USB.
He is sending me a 4 position control unit to do some Node Red testing with, but it looks like programming a flow will be rather easy.? I think I'm going to set the USB up with the ser2net protocol so any device on the network can communicate with it via the Pi.?? In the future he is going to automate the manual/automatic button so it's fully remote, but needs to sell out of his current inventory.? He suspects maybe around the first of the year the net boards will be ready.? He will be at Hamcation in the flea market selling his ant switches.? Once the flow is done for the RAAS-4A, I'll post it in the files section. Thanks Kyle AA0Z |

Finally got this device and I'm having some issues with the Pi seeing the USB device.? Here are the dmsg logs.

Any idea on how to make this device communicate correctly with the Pi?? I get the same type of error when plugging directly into the Pi on the USB 2 or USB 3 ports.? When I plug in the EA4TX box, I get something like this in dmsg and everything is good.?? [676121.199617] usb 1-1.3: USB disconnect, device number 4

Looks like the new device is enumerated as a USB HID device.? There was some work done with the Telepost LP700 to have that HID device show up and allow access in Node Red. I think it was Warren that had written up notes on how to install the LP700. Might be worth checking the file section in the LP700 flow for notes.? 73 Dave wo2x On Mon, Dec 5, 2022 at 1:19 PM Kyle K <kylekrieg@...> wrote: Finally got this device and I'm having some issues with the Pi seeing the USB device.?

hey Kyle,
Any news on your NR integration of this WA4MCM antenna switch? Wonder if his planned "auto button" upgrade will affect anything, or if units can be upgraded in the field..... I'm still plugging away on my MFJ remote switch, trying to find something that works. This could be the plug-and-play answer. 73, Tyler N4TY |

Hey Tyler,
Here is the latest.? After figuring out the USB module was bad in the WA4MCM switch, I got a new module and it looks like the Pi can see the unit now as ttyUSB, which is good first step. I'm going to start on the programming next week.?? I think he's planning on having the unit be fully remote, as in, if you leave the house and it's in manual mode, via Node Red you'll be able to put in "remote" mode and use NR to control.? Hope that answers your questions. Kyle AA0Z |
开云体育Hi Kyle,You might want to change to address the USB device By ID instead of TTYUSB in case other USB serial devices will ever get plugged in. I’m sure you know this and are just debugging now. 73 Dave wo2x On Dec 18, 2022, at 3:05 PM, Kyle K <kylekrieg@...> wrote:

开云体育Windows will remember and reserve the com port number for FTDI chipset USB devices based on the serial number in the chipset in the FTDI USB interface.?In Linux as a default the TTYUSB ports are enumerated in the order they are plugged in and leads to possible issues using the default name. I like to use the ID of the USB device in the serial node so it always uses the correct cable or interface, no matter the order they are enumerated.? One of the videos on my YouTube channel shows how to get the ID and how to set up the serial node. I should do a new video and condense it down to just this topic. It would help people new to Node Red.? 73 Dave wo2x Sent from my waxed string and tin cans.? On Dec 18, 2022, at 7:05 PM, Kyle K <kylekrieg@...> wrote:

开云体育We can do a quick Zoom if you like. I’m heading in the hospital early Tuesday morning. Let me know if you have 15 minutes and when. It is straightforward but quicker to just show you on Zoom.73 Dave wo2x On Dec 18, 2022, at 8:57 PM, Kyle K <kylekrieg@...> wrote:
