How can i trigger a external antenna ldg at-100 pro tuner with SmartSDR?

Erv

I have a LDG AT-100 pro that the manual says it can be interfaced  directly with many popular transceivers it appears that its 1 std two wire 1/8 jack.. Is it possible to attach this to a flex 6400 and tune it via SmartDSR..Is there a accessory jack/ set of pins that would work?  just ordered a 6400

I am using the AT-200ProII with my 6400M. No extra connections needed. Just hit the radio tune button and the LDG will do its thing when needed.

The tune button on the tuner won't work with the FLEX, you have to use the radio TUNE button as Jonathan has said.

I was hoping I could access and control it remotely  with the SmartSDR software...
I figure worst case is I walk in to the Ham Shack and hit the tune button... But it would be really nice if I could tune via SmartSDR

Yes, SmartSDR has the same tune button

You configure the LDG to detect the radio rf and tune the antenna if the SWR threshold if over say 1.6 or what ever you want. You would then just hit the SmartSDR Tune button and the LDG would tune the antenna.

So is the accessory connector have a pair of wires that can be controlled by SmartSDR that would be connected to the LDG ?

There is a coaxial plug Jack on the back of the LDG

I cannot understand why Flex does not provide a signal to one of the RCA jacks to close when Tune button is pressed. Many have resuested this over the years.
