Re: SPE Linear V1.1 flow uploaded to files section

 

Hi Ron;

I'm new to Node Red, and learning quickly (drinking from the fire hose, as it were).? As a means of jumping in with both feet, I installed your SPE Linear flow as the beginning of a Dashboard that I'm building for my station.? I'm running Node Red on a Pi 4B (2GB), and your flow started working as soon as I configured it, which is great, but I do have one minor issue.

Everything seems to work except the temp gauges.? I initially commented out the Centigrade line and un-commented the Fahrenheit line in the initialization node, but that didn't work at all ¡ª the gauges all still showed ranges of 25 to 65, and none of them showed any reading.? I then restored the default for Centigrade in the Initialization node, but now I see no reading on the Temp (Lower) and Temp (Combiner) gauges, and a reading of 73 (which seems more like Fahrenheit than Celsius) on Temp (Upper).

Have you seen anything like this before?? Any suggestions on how I should debug this?

?

Thanks es 73,
Frank N6OI

Next challenge will be to see if I can get FlexRadio 6400 to work using tailscale. SmartLink doesn't work because the router at the remote site doesn't allow port forwarding.

Re: K3NG arduino-based rotator interface via Pi4 with NodeRed?

 

From any PC, also running and logged into Tailscale:

In a web browser, enter the Raspberry Pi's Tailscalale address, port 1880. ?And a /ui at the end to go to the dashboard.

Or, id you are local, with both PCs on the same subnet, just use the IP address of the Raspberry Pi.

For example:

100.4.3.5:1880 ? goes to the Node Red Editor
100.4.3.5:1880/ui ? goes to the Node-Red Dashboard.

Re: K3NG arduino-based rotator interface via Pi4 with NodeRed?

 

Did you "authenticate" your Tailscale on the Raspberry Pi? ?If not, on the Pi, run this command:

sudo tailscale up

You will get a URL for a web connection, plug that into a browser, and that will take to a page to authenticate the Raspberry Pi TailScale to your account.

Now on the Windows side, in the bottom right tray, right-click on the Tail-scale Icon:



You will see a "log in" line. ?Go to that and authenticate your Windows Tailscale.

You connect devices by using the "Tailscale" IP address for the device. ?This will work from device to device via the Internet or on your LAN.

To find the Tailscal IP address for the desired device, again, right-click on the Tailscale Icon in the lower right tray and to the "Admin Console." ?Here you will find a slit of your devices, their status, and their TailScale IP address.

On pain meds in hospital currently so if any typos in reply, I am sorry.?

I would recommend all external equipment to be connected to the Node Red server.?

Then Node Red server (PI4) be on same LAN as radio and other network equipment.?

Now when you want to access and monitor the dashboard you have several ways. The most secure is to use a VPN to access the LAN IP of the Pi followed by:1880/ui?

You can use a service such as TailScale which is free. TailScale allows only registered devices outside your LAN to access other registered devices on your LAN. You control the actual devices that have access via the TailScale VPN. So you can enable the Pi for TailScale and your remote laptop but not your home PC which may contain more secure information. Your decision.?

Another way is to password protect Node Red editor and dashboard then poorer forward a non-standard port to the Pi¡¯s LAN¡¯s Ip and port 1880. Not as secure as a VPN.?

Others can make decisions on various ways you can do it, then choose best method you would like.?

Hi Dave,

I've now managed to access the various flows designed for my antenna switch, rotator and the KLA amp, and they all work but only when my laptop is connected to the same IP router that the RPi is. As soon as I connect from another IP address or internet router or via 4G there is no access to the flows. Any idea why that is??

SVG graphics gurus....need some help.

Just got our EA4TX rotator box attached to our Tail Twister and everything is working great.? Looks like we can keep local control through the Tail Twister and remote via the EA4TX boxes.

Since our TT are North centered, we'd like to have the Node Red graphic to mimic the TT needle.? I've attached the graphic.? The graphic is here.

Re: Sending Hex to Icom 7300 with Streamdeck

 

¿ªÔÆÌåÓý

I don't know anything? about the Streamdeck, but since you mention MS PowerShell, I thought maybe some command-line tricks for accessing a COM port might help you if you are able to generate custom commands from the button pushes.? A quick Google turned up this potential solution for Windows. I haven't tried it, but the article explains the commands they are using pretty well and it sounds like it might be what you're looking for, assuming there is a fixed COM port that you are targeting.


mode COM22 BAUD=38400 PARITY=n DATA=8
set /p x="hello" <nul >\\.\COM22

Re: How To : ser2net - Serial to Network Media Converter with a Raspberry Pi

 

¿ªÔÆÌåÓý

Hi

?

As a curiosity related to the ser2net program. I contacted its author Corey in 2019 since I was looking for the option of being able to support several simultaneous connections, so that it would allow several TCP connections to the serial port. Corey provided me with version 3.5, which was already working, although he told me that V4 would be coming soon. At the configuration level they are very different since, for example, version 4 is configured from a YAML file, so it is very different.

?

But the greatest anecdote is that Corey belongs to our community, he is AE5KM

Re: How to change default name for FTDI USB serial node to use cable ID

 

¿ªÔÆÌåÓý

Hi Kyle,

?

When you have several of my devices connected to the same RsPi, I recommend that you use the UDEV service, because it will allow you to assign a nmemonic to each device so that you can identify each one of the boxes by serial number.

?

As you can imagine if you have only one device (for example a RemoteBox) you will find that when connected it appears as /dev/ttyACM0. When connecting a second (for example an ARS motor controller), it appears as /dev/ttyACM1, and so on with others. But the problem is that you can never know if a device is assigned to ttyACM0 or ttyACM1.

?

The solution is to use the UDEV service. All RemoteBox, ARS, StackMain, or any EA4TX device use the same Microchip microprocessor, so they have the same VID (Vendor Id) "04d8" and PID (Product Id) "000a" but they have the serial number recorded in the USB descriptor, then using that option in the UDEV service, you can customize and identify each device, so that you can associate a name to each device, for example in your case ARS01 and RB2x8.

?

And with this specific configuration in UDEV, you can make the ser2net service instead of using the generic and ambiguous name /dev/ttyACM0 and /dev/ttyACM0, can use /dev/ARS01 and /dev/RB2x8

?

Example of a UDEV file for 4 devices:

?

I have pending to include a help tutorial on the operation of the UDEV file during these holidays

Thanks to Dave for putting out that video.? I'm going to use it on my RCS-4 replacement flow I'm starting.??

...but another question now has emerged on another project that I did some digging around in.

I got to looking at my pi in the amp rack that has a couple of EA4TX boxes (2x6 pack antenna & tail twister rotator) control.??

I'm using ser2net to send the serial data over the network to another pi running Node Red, so the Pi in the amp rack is basically a serial to network media converter. Works great.??

In the /dev/by-id folder, I only see 1 of my EA4TX boxes.

pi@elayerrack:/dev/serial/by-id $ ls -lah

total 0

drwxr-xr-x 2 root root 60 Dec 18 15:09 .

drwxr-xr-x 4 root root 80 Dec 18 14:17 ..

pi@elayerrack:/dev/serial/by-id $

?


but in the /dev/by-path folder, I see both of them.

pi@elayerrack:/dev/serial/by-path $ ls -lah

total 0

drwxr-xr-x 2 root root 80 Dec 18 15:09 .

Re: How To : ser2net - Serial to Network Media Converter with a Raspberry Pi

 

Kyle,

There is a downside.? It's a 1:1 communication path to network to serial device, or at least my experience is every device I've tried.? Unless that's an advanced setting within the connection config in the yaml file, once a device is communicating through the ser2net service via TCP, no other devices can communicate to that serial device.??
You might consider adding the max-connections option to increase the allowed number of TCP connections.? ? This allows the Node-Red connection and the OEM software at the same time.

connection: &nr8001
? ? accepter: tcp,8001
? ? enable: on
? ??options:
? ? ? ?max-connections: 3
? ? connector: serialdev,
? ? ? ? ? ? ? ?/dev/ttyACM0,

If you are still on version 3.5 ser2net (or older), the old conf file (/etc/ser2net.conf) format would look something like this:
ipv4,6000:raw:600:/dev/ttyUSB_rotor:4800 8DATABITS NONE 1STOPBIT max-connections=3

This also starts the TCP listener only on ipv4 instead of both ipv4 and ipv6

Let's break down one of the serial to network configs

connection: &nr8001 - this is the name of the connection.? I used nr for Node Red and the port number
accepter: tcp,8001 - this is what protocol to listen on the network side and what port number to use to make a connection to the connector.? In the example, it's listening on tcp port 8001.
enable: on - this is to enable connections
connector -? this is the other side of the connection
?- serialdev - specifying a serial device
?- /dev/ttyAMC1 - this is the path to the device (I would substitute the full path here, check Dave WO2X's video on how to find the full ID path)
?- 38400n81 - this is the speed, baud rate, polarity and stop bits
?- local - specifying the device is local?

The man page for ser2net calls out all the different connection types (there is a lot).

There is bug in the bullseye distribution Raspberry Pi config and sometimes the ser2net starts up before the networking starts up, so we need to add the following lines in the /lib/systemd/system/ser2net.service file

Add these two lines in the [Unit] stanza
After=network-online.target
Wants=network-online.target

pi@elayerrack:/lib/systemd/system $ more ser2net.service
[Unit]
Description=Serial port to network proxy
Documentation=man:ser2net(8)

Type=exec
Restart=on-failure
?
[Install]
WantedBy=multi-user.target
pi@elayerrack:/lib/systemd/system $

After your done editing all the files, restart the service with sudo systemctl restart ser2net.service or?sudo service ser2net restart.

Issuing the command netstat -l will show you all the ports your Pi is listening on.? Look for the TCP ports specified in your ser2net.yaml config file.? You should see something like the below (but more output).

Active Internet connections (only servers)
