I changed the subject

?

This worked 3 days ago before I pulled out the W2 and replaced it with the LP100A.

?

oh, wait... maybe not as this looks like the LP100A settings now.? You might have to revert to Dave's notes.

Dave and the?group

?

Good thought about using the full name of the FTDI cable.? Here is a screenshot with the Rasberry?Pi DEV file on the left, and the Node-Red Serial In node on the right.? Node-Red found the DEV file, so that seemed like good news.

?

However, the W2 Wattmeter does not respond to Node-Red.? I am using?the "official" Elecraft serial to USB FTDI cable.? Node-Red appears to see and like the cable.

?

Dave and Mike, you each use the W2. ? Could you send me screenshots of your serial in/out "advance" configurations,?for the W2?

In my hours of research I remember reading some USB toserial adapters would go “stupid” if addressing them by the port number. It was recommended to address them by the serial number of the cable which is unique with real FTDI chipset cables.

I believe that is also how Flex keeps track of the cables plugged directly into the radio.

Thanks, Mike.?

I will continue to try different settings.

Hi Alan

?

You might have to play in this area, edit serial port node.

?

The LP100A starts with a ; that I use to start the listening process.

?

However, I have found a bug on my USB ports that they don't listen at times until I change the Split Input time (or something) that caused the something to get reloaded it seams.

I see you are using Node-Red serial in and out nodes.? With cables? ?

?

I am having problems doing the same here.? I have had success with serial to IP converters for remoting the?ports.? I am now trying to co-locate the Raspberry Pi and use cables for the serial connection.

?

However, when I use a Serial to USB FTDI cable, my Node-Red sees the cable connected to the USB port, ?Node-Red says it is connected to the port, but will not pass data thru?? All of the basic serial settings are per the device's instructions.

?

My current instance is with the W2 Wattmeter.? I am using the Elecraft supplied serial to USB FTDI cable plugged into the Raspberry Pi USB2 port.

?

Are you using FTDI Serial to USB cables?? I know you have previously used the Serial to IP convertors?which I too have used successfuly.? Did you find any other settings or drivers necessary?to make the cable work on a Raspberry Pi?

I'm still working on it.? The key was making sure I don't corrupt the read of the initial data.? I'm adding more display info.

?

I took out the Gate since the LP100A handles clearing the display nicely.

?

I'm reading every 100ms to try to catch a nice Peak value, but I am checking with Telepost to see if I actually need to do that or if the LP100A actually holds peak from the last x-milliseconds.??

?

Still a play in progress!? :)

Interesting.?

I have to Look at the WaveNode manual. This might be a good starting point for Bret and his meter. I’ll check it today.

?

Mike, can you post the code?

?

I have seen the internal meter info from the radio jump to incorrect values on the dashboard (internal voltage and PA temp). I fixed it by rounding off to one decimal place.

Here is the flow for the LP100A and I even found the STRING node that made this so simple

The GATE opens when the radio is in transmit.? I added that on the Elecraft W2 as I was getting some weird readings while in receive.
