Need technical support from FlexRadio? It's as simple as Creating a HelpDesk ticket.
Is there an API for controlling a USB Bit cable as stand alone Digital Outputs?
I would like to use a bit cable as DOs to control various equipment in the shack. There doesn't seem to be a way in SmartSDR to do this as the cables appear rigidly mapped to a selection of triggers.
I little window in SmartSDR to simply control the levels of a cable would allow a lot of functionality within the realm of SmartSDR, but I do understand that resources are limited in the radio.
Is there an API to control the levels of the individual pins on a USB Bit cable via FlexLib?
I don't know of such a command in the API. If you are writing code anyway, your own bit cable from the controlling PC may be the way to go.
Another approach is to use an Arduino, Raspberry Pi or Teensy board to control the external equipment. It is fairly straightforward to use any of these devices to communicate with the Flex 6000 series radios using the API.
What equipment are you trying to control? Are you making control decisions based on frequency, mode or something else?0
The Flex API communicate to/from the Flex Radio via TCP, ethernet.
Using Flex API commands, via TCP, you can configure and turn off/on the USB cables.
If you need a specific Flex Radio variable, via a serial USB connection, you could code a application to bridge from TCP to Serial.
Thank you Alan and Len.
Alan, I did see the API to allow on/off and configure but not an API to control the individual pins which is what i am looking for.
Len, nothing I am controlling is related to radio settings (frequency, mode, etc.) and the controlling PC is not present at the radio location. Some examples for control are a remote trans-match and an antenna switch. If the FlexLib cannot do this I could surely do it with an ESP32 or Arduino but it would be very nice to have SmartSDR via the radio itself be able to toggle lines on the bit cable. It would enable a tremendous amount of station control without using additional apps and HW.
Cheers to all,
Hi John, another choice is one of the WiFi remote switches. I found a cheap ($20 USD) 4-channel WiFi switch on Amazon and use one channel to power my Flex 6400 up or down using the Remote On jack. The other three channels choose among 3 antennas.
It has buttons so that when I am home, I just use the buttons. When I am operating remotely, I use the supplied app (eweLink) on my phone.
It was very easy to set up and didn't require any programming on my part.
I'm not at my computer right now, so I don't have the Amazon link, but I can send it later today if you are interested.0
I would be interested in the link for the WiFi relay when you have a chance. I do have a 16 channel USB board here that I was thinking of connecting to an ESP32 running in USB host mode and building a WiFi UI for it on the controller.
The board you are suggesting does sound a bit more economical though.
Thank you Len,
I saw some of these (without the enclosure, the enclosure is certainly a bonus) but I was skeptical regarding the timed MC 'inching' feature. However, the timed MC actually looks very useful after I took the time to actually read the description. Going to give it a try.
Sounds good John. I have had mine for a couple of years, and it has been trouble free. The Android eWeLink software works great. I set up 5 scenes:
Flex 6400 ON
Flex 6400 OFF
80 M sloper
The three antennas are set up so that if I select one, the other two are un-selected. If I press the buttons on the box, I have to manually unselect any other antennas that are selected.0
Sounds like you probably use the smart phone app even when the box is next to you :)
Now I just need some digital inputs so I can read the status of the PA.
Thanks for all your help Len.
