PTT Outputs RCA, Pin11 - I am lost

Have a 6300 - looking to have PTT out cause a pixel to **** the power to it's pre-amp.  I almost understand .. but .. not quite.
On the FLEX-6700 and FLEX-6500 there are four PTT outputs. Three are RCA jacks on the rear panel, labeled TX1, TX2, and TX3. The FLEX-6300 has one RCA jack labeled TX. On each of the radios there is an output on Pin 11 of the Accessory connector on the rear panel as well. These outputs are isolated, and each one can have a specific delay. Some users will want to utilize the delay settings to sequence switch external equipment. 
So, on the 6300 there is an RX labeled TX .. can I use this or not?  Since SmartSDR can only configure Accessory (Pin 11), will RCA still be high on PPT or?

    If you plug your RCA cable into the TX RCA jack on the 6300 and plug the other end into your Pixel RCA Jack then under "settings/transmit" enable RCA TX1, it will key the Pixel unit off and on as you key the radio and protect the Pixel's amplifier from overload. Of course you will hear the relay clicking.
    Same goes for Pin 11 if you enable ACC TX. They are one and the same on the 6300 so you can control only one device at a time without adding external switching of some kind.
    Before make the connection you can try shorting the Pixel's RCA jack to ground and see if its relay activates. You'll hear it. 
    I take no responsibility for anything bad that happens.
