Re: Looking for Yeasu tun/lin TTL protocol

Subject: [YaesuTuner] Looking for Yeasu tun/lin TTL protocol? Hey guys, here is some history to help understand my need;
in the ft8X7 and ft100 radios Yaesu was offering a mini din 8 pin connector that had 3 functions, CAT TTL, TUNER, LINEAR, through simple config in the radio, this is actually back in FT710 that brought back CAT3 via TUN/LIN minidin8 connector.
between the these two groups of radios they dropped the CAT TTL function of the TUN/LIN mini din connector for a separate RS232 connector, ?part of that minidin8 TUN/LIN connector dual usage is a simple TTL connection using the same pin out as the CAT TTL as for the ft8X7 connector.
I am looking for the commonly used TTL ?communication protocol to control the linear via the TUN/LIN minidin8 connector.
let me be clear I am NOT looking for the Yeasu CAT protocol, I don’t think (could be wrong?) they use there CAT COMMANDS for this?
let me know.
specific info on the link specification (speed, etc…) would also help me.

Re: Looking for Yeasu tun/lin TTL protocol
Thanks Chris, I am aware of the diff between RS232 and TTL, if you have a chance please look in the support section of my website WWW.VE2DX.COM?for my Whitepaper called TrueTTL. I need TTL connection for some of my Yeasu oriented projects, I am hoping the Yaesu Protocol used over TTL on the TUN/LIN connector might be usable for my needs? But can’t find any documentation on it, and no it isn’t CAT, except on the FT8X7, FT100, and FT710 when properly configured, all other radios don’t support CAT on that connector even if it is EVERYWHERE!?! 73 Richard VE2DX WWW.VE2DX.COM

Re: Looking for Yeasu tun/lin TTL protocol
The RS-232 connector presents the same information except it's not TTL. TTL stands for transistor-transistor logic and has generally referred to using 5 volt logic levels. Most ham radio implementations are actually open collector pulled to ground.
?
It's still a Yaesu CAT interface.

Have not used nor do I own it but from some reviews it has a limited range (one quoted 3:1) so if this is true anything far out of resonance will be a no go with this tuner. Not necessarily a bad thing but just have to be aware of this.

Will be very interesting. The fc40 does a good job if the antenna is complemented with a unun/balun.

I think that the key information that I'm looking for is how the tuning command is initiated. It seems that the fc20 is the master and polls the ft100 to check for the TUNE button. Taking over, it sets the ft100 for tune power until it's happy with the swr. But I can't find confirmation of that.
Now looking at serial comms sniffing tools to find out what these two are saying to each other before and during the dance!

Probably of no help,? I have the FC40 ATU the schematic shows all the signal wires going directly to the main processor. The pins are tx inhibit, reset, sense, data in/out, gnd, tx gnd and 13.5 v.?

ALSO HAS ANYONE FIGURED OUT A WAY TO USE THE FC-20 AND CAT CONTROL AT
THE SAME TIME?
Interested in following this up. (I have asked the same question on the FT100 forum/s)
Short answer - I haven't found anyone.
Longer answer ….
Clearly, the antenna tune mechanism is fundamentally different to ATAS tuning, where the TRX (FT100 in my case) provides a dc control voltage for the antenna?and monitors SWR during tuning itself.
It seems that the FC20 is continuously checking the FT100 status using CAT and captures a TUNE command. It then takes control of the FT100, sending back tx mode, power and key commands to provide an appropriate rf level. It does this until the FC20 is happy with the SWR.
That description is guesswork, however, based on what I observe doesn't happen and on how I would use the available signalling.
So the problem is that FC20 is continuously keeping the CAT interface busy and that's probably why it's not easy to share the CAT port.
I believe, however, that nothing's impossible, it's just the degree of difficulty. I can see a solution where a PIC sits in the CAT interface monitoring the comms between the CAT program (say HRD?) and when the TUNE button is pressed, or HRD commands it, the PIC switches the CAT to the FC20, or even emulates the FT100 on a separate tuner data lead. It's only programming,?after all.
I looked into the bhi CAT-Mate. It uses a solution where a monitor switches the CAT lines between two CAT devices?but the manufacturers unambiguously state that this 'Y' unit won't support a tuner on one of the two CAT ports. So the technique is valid but the FC20/30/40 use a different protocol to other devices.
The LDG tuners (YT100 and Z817) also use the CAT interface to set the FT100 to generate an appropriate tuning signal.?As the TUNE command is issued from the button on the ATU, rather than the FT100,?it can switch the CAT control from the PC to the Tuner whilst tuning and then back when tuning is complete. There's no need to monitor the FT100 status for a button press. The LDG tuners have a CAT passthrough port which works in this way. Indeed, this is one solution for me - to replace the FC20 with a YT100 and then add in a PC driven switch contact to 'push' the YT100 Tune button using HRD.
If you find any detail on the FC20 protocol - that is, have I guessed correctly - then I'll happily work with someone to develop a solution. I have a perfectly good ATU (FC20) and don't want the expense of changing it just because I want to remote control the station using CAT!??

Build a fan dipole (several parallel dipoles each for a specific band)
Then your internal tuner could tune that with ease
Autotuner like fc40, sgc (xxx), and some other can easy be used for tuning a
dipole, doublet or a loop.... but the tuner has to be "floating" rf wise
Means ... put a choke on the INPUT of the tuner and also choke(s) on the
power lines ... the tuner has to be isolated from ground if you wanna tune a
doublet or loop
I used my fc1000 that way (on fieldday setup etc) ... and a friend from me
uses an sgc tuner that way

I decided to go ahead and get the radio to see what could be accomplished
with the internal ATU. I installed a 2 band dipole (10M and 20M) and the
radio will only autotune on those 2 bands so I'll still be searching.
