Re: W2 wattmeter support


 

That is the same Cable as I am using, and the latest Flow from Daves Group.io I have several COM ports listed not after playing around with the WN2 Watt Meter and making sure the FTDI driver worked with the FTDI that works in the FLEX radio's USB ports so I may have to figure out how to get rid of the ones I'm not using or figure out how to set the Node-Red COM port by the actual Cable name.?
All this?is really new to me so just learn as I go?

Thanks guys

I no longer use the serial to TCP converter.? If I were I would use the TCP in and out nodes.?

I am now hard wired from the W2 to the Pi as described above Using Elecraft serial to USB FTDI cable.?

The Serial Request node seems to coordinate in/out more to the W2¡¯s liking.? I never was able to get the two separate serial in and out nodes to talk with the W2.

Baud rate should be 9600,8n,1

?You say the usb cable shows as connected. ? Good Linux found the USB port.?

Use the same USB port with ?the settings I sent you, and use the TCP Request node instead of the two TCP in and TCP out nodes.? Be sure to remove the unused TCP nodes.? Then reboot pi, reboot W2.?

Yep tried that I am now testing on the bench using the Windows App and all work A-OK, Just wondering do I have to set the COM port serial?number in Linux anywhere? also what baud rate does the W2 take??
looking at the Flow and seeing what COM Port is available it shows 11520 and 9600 the windows Device manager uses 9600 Baud??
Thanks a lot Alan?
Ill give a try here in a bit on the Node Red server again after dinner

Bret- Re-boot the Pi, then if nothing, power cycle the W2 (unplug, plug back in).

Hi Dave, Hay got the Elecraft W2 Wattmeter today and got it plugged in with the included USB serial cable BUT I am not getting anything coming?out of the W2 to the FLow wonder when you have a minute you could poke around here and see what I have wrong that catch's your eye. The USB serial cable shows connected in the flow and nothing popping?out looking at the Debug for that Flow?

Phone number here is 4357499012?
Thanks a lot

My display flow for the wattmeter is based on the decimal spacing returned from the F command, F00125D2; would be 1.25 watts. And if the third place in the information string is 1 then meter scaling is set for 0 to 2 watts. I was able to do some pretty cool stuff.

I just need guidance on what people want for control of the meter.

I use the metering in the KPA1500. I kept monitoring and control simple, to what I need for remote operation. But the nice thing with Node Red is any avalable command or info returned can be displayed. It is just how crazy you want to go.

For the people new to Node Red, install it and load some flows to look at the different nodes ?nodes to see how we manipulate the data. Looking at examples helps to learn.

As always, ask questions here. Pretty much any equipment with serial, USB, or IP can be added.?

Having used a W2 until last week (but for about 10 years previous) I found that I needed to hit 'scan' more than once.

Changing scales requires you to do math on the reported values.

BTW, for Scan, I think it requires a special firmware from Elecraft, but you would need to confirm they actually made the firmware public.

Actually I don¡¯t have any at the moment.

Yes, I¡¯m getting my way around. Currently I¡¯m adapting some of our flows to my set up and combining them. And just started reading about Node Red and APC UPS.

Hi Santiago,

Hope you are progressing with Node Red.

What wattmeter do you use now? Does it have connectivity either via serial or USB?

Hi all,

I have finished the display portion of the W2 wattmeter flow.

What control functionality would you like to see? Forward power meter in auto range or manually set? (I personally like auto range).

Sensor auto scan or manually selectable? Or a choice between the two?

What other controls?

Once I get some feedback I will be able to have a flow publicly available to test.
