Update on my attempts?to establish a serial connection using a serial to USB FTDI cable from the W2 meter to my Raspberry Pi, running Node-Red.
It is now working.? Simple solution.? I found the W2 meter had to be power cycled between serial connection configurations changes.? In the end, I found the "default" settings within the Node-Red serial in/out node worked just fine, after power cycling the W2.

I do not use any serial ports on my configuration although I may want to use one in the future. ? I do not have the W2 but use the meter built in the KPA1500 which I believe is similar to the W2. Bret, give me a call when you have time and I¡¯d like to connect to your computer with TeamViewer and see what is coming out of the serial port using a debug node. If it uses same commands as the KPA1500 metering then I can probably adapt my flow. ? 73 Dave wo2x ? ? From: [email protected] <[email protected]> On Behalf Of Michael Walker

Subject: [nodered-hamradio] W2 configuration ? 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. ? 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? ?

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. Dave wo2x ? I will continue to try different settings. ?

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 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!? :) ?

I fixed it by rounding off to one decimal place. Dave wo2x
