Unfortunately, the Z817 does use proper CAT commands to set the FT81x to low power transmit when tuning. It's fixed at 38400 baud, so the pass through won't work for the OP.
?
You can use the Z817 as a tuner without the CAT cable, i.e. connect the display directly to the radio.?
?
Full detail in the Z817 instructions...

Hi Michael, ? If I’m not mistaken, the tuner only uses the Band Data pin from the radio to tell it what band you’re on (plus Gnd and power, of course). ? The CAT Tx and Rx pins are different pins and, to my knowledge are not used by the tuner at all and are just passed through to the socket on the tuner. ? Therefore, it should not be a problem to change the data rate for the CAT port to 4800 bps. ? 73….Eric VK2VE. ?

Subject: [ft817] FT817 compatibility? This is kind of a continuation of the display thread/subject. I received the display yesterday. It came with the mini DIN cable and my 817 was able to power it. However, I am using the cat port for the LDG Z817 tuner with radio menu setting at 38400, the new display requires a cat rate of 4800. The LDG tuner has a pass through cat. Not sure how to make both work. Can I just set to the lower rate, 4800 and both will/should work? There is also a RJ45 connection option that I haven’t tried yet. Thanks all

Re: Larger/brighter Display option
Is 817 Commander a better option than Pocket RxTx lite? Has anyone tried/used both? Mike Davis WA1MAD

Re: Larger/brighter Display option
Well, when you ask a question on this group, you sure get some very interesting and helpful answers. I now have a CAT cable coming, an older Android phone repurposed with pocket RX TX loaded and awaiting the cable, AND a display on order from Ali Express. All this should keep me busy and confused for awhile. My only concern is that on a YouTube video, the display worked on an 857, and 897 but not the 817. We’ll see. Steve, KB1CHU, a nearby ham, has offered support to see what we will see. I’ve even thought that just maybe, my unused backup automotive camera might work. Thanks to all, for your suggestions.

Re: Larger/brighter Display option
Julio EB4CUV and me designed a nice CAT display for FT817 which looks like an Icom705
Still some units available. But it is intended for V-UHF and microwaves use (along with the proper transverter)
Not for HF and also making exclusive use of the CAT port

Re: Larger/brighter Display option
I also bought a mini din bluetooth CAT device. It works well with RXTX and even with other PC applications. But I encountered a problem: when you turn off the FT-817ND the bluetooth device does not turn off, checked because its blue LED does not turn off, and continues to consume the equipment's battery. If you forget to disconnect it, you may find an irrecoverable battery.

Re: Larger/brighter Display option
Thanks Steve, I may not get it, since I keep getting messages that my order needs to be completed, yet another message that it’s o n it’s way. I think it’s a PayPal thing and really has been or is in process of being shipped. I also bought a mini din bluetooth CAT device to transmit to my Android device. I can then use RxTx app or the other one mentioned. I’m obviously totally out of control. My New Years resolution…”do nothing different” Mike Davis WA1MAD

Re: Larger/brighter Display option
It will hopefully work. The guy on YouTube couldn't get it to work. 857 and 897 worked. I also just ordered a bluetooth CAT device that works with the Android rx/tx app. Obviously, I'm out of control...lol Merry Christmas

Re: Larger/brighter Display option
I just watched a YouTube video on the 12864 display on an FT857, then an FT817. It worked on the 857 but not the 817. I should have watched the video before ordering yesterday. Grrrrr

Re: Larger/brighter Display option
Hi Mike,
?
I have used the FT817 commander android app with an old android tablet and an OTG cable.? It also works on the Z-817 tuner pass through.??

Re: Larger/brighter Display option
Ah, the tuner.? Yes, that can complicate things, but looking at the
Z817 tuner manual the tuner has a "pass through" CAT port on the
back.? You should be able to connect the display to that port - it
looks like a computer to the tuner - with the tuner connected
directly to the radio.? Just make sure all the BAUD rates line up -
display, tuner, and radio.
Good luck!

Thanks Greg. I’m nowhere as talented as you in understanding ?the
options. I do have a spare backup camera kit…hmmm. My other
concern is that I’m using the CAT connection for the Z817 LDG
tuner. So unless there is a way to use both devices together or an
A-B switch, assuming baud rate etc are the same, it just
complicates the radio. Maybe my pico LED front illumination idea
is the easiest, if not very elegant.

I've not used that particular product, but I don't think
there's much more to know about it.? Connect it to the radio
and get the two to talking.? The device just loops through
fetching the parameters, displaying the information on the
screen.? You probably want to cobble some sort of case for it,
to protect the electronics.
I built something similar from a Raspberry Pi 3B.? I have the
radio in my car, and as you can imagine it's impossible to
read the display while driving.? But the car's in-dash radio
display has an input for a back-up camera, so I wired the Pi's
video out into that and wrote a short Python script to read
the radio's frequency, mode, and such, displaying them on the
screen.? The car's display is FAR more visible, and with the
Pi I can run other radio-related apps such as YAAC for an APRS
map.
