Just thought I would again thank you for your work on this flow.? The revision works !!!
Thanks again,

Re: Updated KPA500 flow available
Hi Dave
I think in my Flow I was able to turn it on remotely by sending a P command to the radio over the Serial port.? This turns the amp on in the boot loader.? I did have this working.??
To turn it off, I had this
I can test your modified flow, but it won't be until later in the week.

Re: Help with addition to DLI flow
Alan, More than expected ¨C Thanks for your work I am one of those who powers down the station at the end of the day.? ?The power down/up without this delay was causing problems with the Flex 6600. ?In the short time I have used the proper sequence to power up/down all seems as it should be.? Your flow will help eliminate my pilot error.? Thank you I have installed and connected the flows you instructed ¨C There is a minor glitch that may be caused by my particular set up.? I will email you info Thanks again, Dave K9UK ?

Re: Help with addition to DLI flow
I can't seem to find the email to reply to directly, but it is only the M models that we suggest the 2 minute delay.
It is to allow the Windows Embedded in the M model tablet to do a nice clean? power on first before then starting the Maestro program (power button) to start up.

I should provide an explanation?for the relays used in the Flex Power Sequencer Flow:
Boot Relay - Wire to your relay application that switches the Flex Server "Remote On/Off" RCA connector on the back of the radio.
Power Relay - Wire to your relay application that switches the 13.8 VDC power to the Flex radio.

Dave,
Total node-RED newbie here. First heard about it during the QSO virtual hamfest. I don't know what I don't know!?
To control the KPA500:
- What are the hardware requirements?
- RPi? What version, etc.
- Does it connect to the RS-232 jack on the KPA500?
- If I get the hardware setup is it possible to install a copy of a proven Flow for the KPA500?
- Is there documentation that would describe what I need to get started?
Sorry for such basic questions but this is new to me.
Thanks in advance,
Jack

Re: Help with addition to DLI flow
Thanks for the response Dave,
I received instructions from Flex regarding the requirement to have the PS to the radio on for at least 2 minutes before turning on the radio either remotely or from the front panel. I have manually been doing this for a short time now and it seems to be working.
Again thanks for your flow and help,
Dave
