Re: Kenwood CAT to relay example.json..... PROGRESS

 

Sorry I was out on a fairly long road trip today and then crashed and burned on the couch for three hours. Now with somewhat fresh mind....

OK, jogging my memory and Dave's experimenting around here is what should solve it to get the input from the Kenwood intact so you can then pass along to parse.

On the Serial In (or Serial Request), double click it to open then click on the pencil to edit. Change Split Input to On Character and the ; (semi colon) character. Each response from Kenwood is terminated with a ;
That should get the data flowing and you should see the FA responses. Then try the example flow I gave you and it should show the frequency.

For others having Serial In issues, look at the protocol for whatever device you are trying to connect to. For example, the DUC-1/Hygain rotor protocol uses a terminator of ; (just like Kenwood) and you need to set that as the split input character in the Serial node.

A break through of sorts late this afternoon

In the port setup is a group of boxes under INPUT.
The second row down is a line SPLIT INPUT with two boxes which default to [On the character]and [\n]

Changing the [\n] to "A" ( one of the characters in the serial string we are looking for) allowed information to start coming out of the serial port into the rest of the flow.

I am sure that "A" is not likely correct it certainly screws up the serial message parsing for the later logic to act on But it points as to where to start looking further ....... Is "\n"
supposed to be a number or \(number) maybe?

Can anyone point me to a complete set of DOCUMENTATION that defines what all the choices under INPUT are and how to choose appropriately?

Dave WO2X and Alan thanks again for all your suggestions earlier. Dave a video call tomorrow at this point is not necessary. Pointers to real documentation if it exists appreciated though. Until that surfaces I will likely play the "monkey at the typewriter" till I figure out what goes in all those boxes and why.

Tomorrow I will point the output of the Serial node to Msg-Payload in DEBUG mode and see what the data string really looks like

My thinking is correct (verify) that if the SERIAL NODE is now

I think \n (ASCII char 10 is new line feed and is different than \r (ASCII char 13) which is carriage return. It would be \r\n for both, or at least that was how I remember it from my days at staring at an HP serial protocol analyzer.

These devices are designed to be switched from a GPIO pin. ?I have several.

They safely control 120VAC loads, with overload and surge protection. ?You could in turn use it to switch a 240 VAC load on/off through a two pole contractor, with 120VAC coil.

Re: File /wo2x flows/Kenwood CAT to relay example.json

 

Dave

I have a little experience with using the Kenwood protocol.? So just a guess here.

Switch to using the Node-Red Serial Request Node.? Set it up as you did the receive Node.? In fact, your cable should now be stored as a configuration and show up in the serial request node's pull down com selector.

Put an "inject" Node on the Input of the Serial Request Node.? On the inject node, set it to inject a string, "FA;".? Inject and watch the output of the Serial Request Node.?

"FA;" tells the radio to send the VFO frequency, and it should reply with the frequency.

To delete all the old references to serial ports in the serial node, double click the serial node. Click the pencil to edit. Upper left of that window select delete.

Use pull down to select next serial device. Use pencil to edit. Delete. Repeat for any remaining serial cables.

Then it will prompt to create new. When you were in the /dev/serial folder, highlight the serial cable in the serial by ID folder. Right click and select copy path.

Back in Node Red when you open the serial node and create new. Paste the path you copied for the usb to serial adapter. Set baud rate. Set timeout to something like 500 ms. It defaults to 10000 ms. This is important!

Been to the one in Rochester quite a bit when I had to do a service call at Eastman Kodak.

Good food!

OK

I removed the TCP Request Node and routed the Inject Node to the HEX to string Converter node. Test that with a simulated KENWOOD serial frequency command string <FA00007150000> and it outputs the desired relay command. in the DEBUG window...So far so good

Next I replace the INJECT node with a Serial-In Node. After the proper baud rates(4800-N-8-1), etc the node registers "Connected". I take the serial cable from a known working connection ( Radio to Stepp-IR controller) and attach it to the USB serial connection on the R-PI. My USB/Serial dongle has a series of LED's in it that allow to me monitor activity. When the frequency is changed the RXD line flickers with activity so I am pretty sure traffic is flowing in to the serial in node but apparently nothing coming out to the HEX/String converter

What did I miss??

Think of Node Red as a flow chart. Input data, pass it to next node, do something with dat, pass it along, do something, etc.

Do Google searches for example Node Red flows, especially for Home Automation. They will give you an idea on how Node Red works. It is very easy once you start playing around. There are plenty of flows in the file section which will give ideas on how to accomplish a number of things.

I get

Are you saying I should see USB_FTDL_FT232R_USB-UART_ ( NUMBERS) ? If so not there

/Dev/sersial/By-id" the device comes and goes with the plugging and unplugging
"USb_ftdi_ft232r_usb_uart_( lots of numbers)"

Under the "Dev/USB".... ttyUSB0 does not move if that makes a difference

I have used this dongle many time on my windows machine , like I say it is a treat to have the clear case on the DB-9 serial end with all the little lights and RXD is definitely getting traffic ( hook it up with out the null modem adapter and no RXD traffic light) as further verifiaction

Suggest your next step is to ensure the cable you have selected in the Node-Red serial node is the same cable as you plugged in.

On your Raspberry Pi, using the file explorer, go to the "/dev/serial/by-id". ?Un-plug the cable. ?The entire "serial" directory will disappear, if this is the only cable. ?Otherwise, note the cable names in the "by-id" directory.

Plug the cable back in. ?Note the cable should now appear in the "by-name" directory with a name.

Ensure this cable name is the same as you have selected in the Node-Red Serial Node. ?If not, change the cable name accordingly.
