Remote Footswitch - How to (LAN/ VPN solution)

First, I want to thank Al, K0VM for this solution.  He provided it just as I needed it.

I operate remotely 99% of the time, however, when I don't have my Maestro handy, I still want my foot switch.  

This works for SmartSDR CAT both with and without SmartLink running (updated since previously written).  mkw - 03/2019

Using CAT and SSDR, it is very simple to make a remote footswitch.

Take any RS232/USB adapter that is recognized by windows.  Check in Control Panel to make sure you can see it.  In  my case, it was Com80 (I need to clean up some ports :) ).




Now, with that running, head over to CAT and Create a New PTT entry.

  • Serial Port - Existing - this means you are using a physically installed port on your computer (RS232/USB adapter)
  • CAT COM: - the same port you set up above
  • RTS is selected
  • Polarity - Active Low



Lastly, you need to know make up an adapter for your foot switch (or hand switch).  

Wire your foot switch to:

Pins 7-8 if you select RTS above
Pins 4-6 if you select DTR above.

If you can't solder, these are a quick solution.



There you go.  Now, when you push the footswitch, the radio will go into TX while running SSDR remote from the radio.

Again, thanks to Al for the idea.

CAT does work through SmartLink. 
DAX doesn't work!

Just documenting that DAX now does work through SmartLink after its recent update (also xDax and xCat work too on the Mac side of things)

I have run into the same problem using my USB mic. I’m not sure what type of cables to use for the above mentioned fix. Do I need another RS-232 type plug to plug into the end of the USB to serial adapter? I’m assuming that this plug then goes into the accessory plug on the back of the flex. In the documentation it says that pins 7 and 8 are both grounded. I’m quite confused. Any step-by-step help would be appreciated.

Thank you, Richard W6RIG

You need a USB/RS232 cable to plug into your laptop.  The foot switch would connect to this device.  

No hardware plugs into the radio as this is for remote operating and you  use our CAT control to send the PTT command to the radio.

Have a look at the instructions above for the step by step layout.

Anyone else having issues with this remote microphone keying solution after ver. 3 upgrade?

6700 aready tried a factory reset.

Some times it will key, some times it will not and some times it will key and stay keyed until re keying and un keying the trigger.

Make sure you connected SmartCAT to your remote PC , in the selection window at the top.

Hi! I would like to use my primary PTT input connected to radio as PTT sliceA and when using "this external USB ptt input" to set TX on sliceB. Would this work?

Should work but not sure if the USB foot switch can produce a DTR / RTS closure because the USB foot switch is made mainly for music applications I think.
At present version 2.5.1 and 3.0.27 CAT port PTT has a bug that sometimes causes problems. Flex seems to think and makes sense that there needs to be a debouncer put on the PTT switch in software.
I use FRSTACK for the Remote serial port PTT which works perfect, Not sure it will work with a USB Foot switch but it sure works great with the USB adapter Serial port so there you go.
Good luck and hope it works

Hang on Bret.  Yes, this does work as described (not a USB musical foot switch) but a simple mechanical foot switch like we use for radios.    Yes, FRStack works great. 

The debouncer bug is not related to everyone.  I tried for hours to recreate it, but I could. not.  And, this was on 2 different computer and multiple FTDI and non-FTDI USB serial devices that were connected to the foot switch.

Goran

In CAT, when you create the PTT Serial port on an Existing serial port, you have to specify which VFO slice it is attached to.  You then may or may  not want to turn Auto Switch TX Slice on or off.  You will have to test it to see if it works the way you wish.

For the actually 'real' PTT lead on the radio, it will always key the radio slice that has the active TX focus.   

I hope that makes sense.

HI!

I found in my old docs that I used sometimes http://www.telepostinc.com/downloads.html LP-FootSwitch2 which transleted one Com to another for my remote PTT at those times...maybe this could be anwser. Will let you know as soon I test it at my friens place.  73CUL
