Re: FC40 connecting cable
Thanks to everyone - I have an 8-pin mini-din 2m male to male straight through cable, cut it and spliced the ends onto a approx. 40m cat5e cable, and it seems to work fine.
?
Cheers, Bill G0VDE.

It's only 10 ft, the supplied cables are 4.9m which is about 16 feet.

Re: FC40 connecting cable
I bought an Appletalk extension cable, as that is 1:1 and socket to plug. I think the regular plug to plug Apple talk cables "cross-over" so are no good for the FC40.

Many thanks - that is helpful.

Re: FC40 connecting cable
Bill,
After looking at the FT-857 and FC-40 schematics, I see that the DIN-8 cable is straight-through.?
Good Luck and 73, Eric / K4PYR?

My simple question is - how is the cable wired - is it just straight through (ie pin 1 to pin 1 etc?). I bought an 8 way AV cable with the correct mini din plugs (so I don't have to wire up these fiddly plugs - I've done it in the past but it is so easy to melt them!). The AV cable is wired straight through but I don't really want to try it without knowing!
I can of course check and compare with an ohm-meter but would appreciate comments please.
Cheers!

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.
