So, I picked up a brand new MFJ-1270C TNC today.
Im trying to figure out how to wire the Radio-TNC cable.

Im being anal here but, I dont want to fry a radio so I came to here.

This is the diagram that comes with the TNC
http://datagrp.vic.wicen.org.au/mfjtnc.htm
This diagram coincides with the manual
1-Mic audio-Black
2-Ground-Green
3-PTT-Red
4-Rec. Audio-Yellow
5-Squelch Input-White

Can I use an RJ45 end and hook it into my mic port?
Here is the diagram for the mic wiring:
http://www.k0bg.com/cable.html
1 +8V DC Out
2 Frequency Up/Dn
3 AF Out
4 PTT
5 Ground
6 Mic Input
7 Ground
8 Squelch Switch

So, if what I want to do will work (This may be the way its supposed to be done, I just dont know) is,

I dont use 1,2 or 5.
3 AF Out - Recieve Audio, yellow
4 PTT (No brainer?)
6 Mic input - Black Mic Audio, black
7 Ground (Another no brainer?) Green
8 Squelch switch - Squelch input - White.

Is this correct?

And thank you!!!!
VRMN

ETA: The cable that came with the TNC has a bare wire that is the "cable shell" ground.
The book says:
"When wiring the appropriate radio microphone connector onto the open end, (of the supplied cable)
wire the BARE WIRE (Cable Shell) to the GREEN WIRE (Cable Ground).

Again, Im over thinking this but, what does that mean?

Yes you can use the Mic port on the radio, I am assuming it is an Icom 706 or 7000. Now the optimum place to wire it in is the RTTY DIN jack on the back of the radio, It eliminates the Mic gain setting and make sit easier to switch back and fourth to SSB.

My IC-706 has a second mic jack in the back, keep in mind if the TNC is plugged into the back the microphone connected to the front will key the rig but it will not produce audio.

I use an standard cat 5e cable on my homebrew interface, try to find some braided cable for the connections.

Pins 5 and 7 are both grounds, however, one will be for the mic audio. You can most likely skip that one and use the PTT ground for both mic audio and PTT ground (pin 5). Don't worry about the squelch input either. You only need four wires hooked up. RX audio,TX audio, PTT and ground.
I agree with stan. Screw the mic jack and go in through the mini-DIN on the back of the rig. (you do have a 706/7000 right?) You can scarf a cable off of an old mouse or keyboard you have laying around.

I forgot to put in that it is the 706MKIIG.
Sorry about that.

Not understanding what youre saying.

I think he meant he used cat5 for the raw cable, no ends. Why don't you go in thru the mini DIN?

I have no PS2 mice or keyboards. I KNOW I KNOW!!!!

The last mouse I had was a failed attempt of a CW keyer then went into the garbage.

ETA: KB to your last post.
I wasnt sure if it was the same pin as a mouse or keyboard.
I guess I know now.

I use a 6 pin cable on the Signalink . The 6 pin data on the back of the radio and a RJ-45 coupler going to my TNC 5 pin, this way I can alternate between the Signalink USB and the TNC.

You can also go in through the 13 pin accy jack on the rig too. Do you have the 13 pin connector supplied with the rig?

Just wire it to a mini 6 pin din and insert in the data port of the radio

Well then, in a pinch you can go in thru the mic jack, but I would look for a mini DIN connector and go in the DATA jack on the back of the rig. That DATA jack is really the best way to hook up a TNC. Going in thru the mic jack means you will have to futz with the mic gain settings when going from phone over to the TNC. Make sure your speech compressor is off and mic gain very low to start.

I used a network cable I had and cut about 2 feet off of it, I then wired the cut end into my interface and just plug the connector in instead of the mic when I want to run the interface.

ETA: I normally make my own network cables, but my RJ-45 crimper is MIA.

Going through the mic port is not that bad, but you do have to mess with the Mic gain and like KB7 said the speech compressor must be off also, or you ALC will be kicking in. The mic gain settings may be different but I run mine at 1 most of the time for the interface, and have to kick it back up to around 7 on SSB.

YAA! Just meter out the pins on the keyboard cable to determine which color goes to what pin and you are GTG. Do you have a bare 5 pin DIN for the TNC end?

VRM, I meant one with no cable molded to it so you don't have to splice wires together. They have raw connectors at Rat Shak.
Have you gotten the TNC hooked up to a computer yet?
IBERIU..VRM is in a good state to set up a node..heh heh..

Ok, I got it now..I just read the packet thread.. Yes a serial to USB adapter might work. You can try it and see. Make sure you set the com port speed and the TNC com port speed the same. The TNC has dip switches on the back for setting the computer baud rate and the radio baud rate which are different.
And with 128K of mailbox space you could be the hub we need!

Carl: What other modes offer a mailbox option other than packet?
KB7DX  [Team Member]
1/14/2012 3:56:07 PM EST
I think PACTOR 3 is about the only other digi-mode that has a store and forward capability. Maybe WinLink? I don't know for sure..I'm still kinda stuck in the 90's when it comes to all the new modes. When I was into it then, RTTY, packet, SSTV and AMTOR were the only common games in town. I still like the idea of a "stand alone" system that doesn't rely on the internet or phone lines etc. Just a guy, a TNC/computer and a rig.

VRM, what program are you going to use with the TNC?

I have something downloaded on the computer at the rig.
Cant think of it right now.
I think it may have been posted in the other thread after I asked how hard it was
to do packet.
AGW Packet Engine is what I downloaded.

The AGW packet engine I've heard of, but I think you need to use another program in conjunction with it. I use a very old version of MFJCOM, but any terminal program like Hyperterminal will work. The TNC can run one of two ways. The first is in HOST? mode. This is where the computer is "the brain" and the TNC is just an interface between the rig and computer. Now wait, you're thinking.."but my soundcard interface already does that". Well it does, but the soundcard interface only sends audio tones to the computer for the soundcard/software to decode. The TNC sends digital data to the computer and uses it's own on-board "modem" to decode the audio tones.
The second is the "normal mode" in which I run mine for now. In this mode the TNC is the "brain" and the computer becomes nothing more than an interface between you and the TNC. I like this about a dedicated TNC. Once it's set up and running in mailbox/beacon mode, the computer can be disconnected completely.
As far as operating during the day, that's what IBERIU and I have been attempting lately, but we just can't make a reliable connection direct. I see his beacon and have seen him connect to my station, but the signal just isn't consistant enough.
But now..with you in the middle VRM..heh heh..

HEY HEY HEY!!!!!!!!
Im soldering here!!
Lets get this cable done first. Oh, I guess LET ME GET THIS CABLE DONE FIRST!

OK, here is what I just got done doing:

So, with the pin diagram on Icoms pdf, page 37:
http://www.icomcanada.com/products/amateur/ic-706mkiig/Amateur_IC-706MKIIG%20Instruction%20Manual.pdf
and
http://datagrp.vic.wicen.org.au/mfjtnc.htm

I wired it as
1 Black
2 Green
3 Red
4 Yellow???????
5
6 White.

Im confused with 4 and 5. I dont think I have a Data, I have the AF out.

What do I do with the bare wire that came with the MFJ cable that is soldered to the "Cable shield"?
Please just answer these questions if you can. I get confused enough when you add info. Yes, Im that
ham/electronically challenged at times.

We're I'm getting closer

The bare wire connect to the shell of the connector. It's the same gnd as the PTT gnd.
So, on the rig..
pin 1 is audio from the TNC. (AF input) BLACK
pin 2 is ground GREEN
pin 3 is PTT RED
Pin 5 is audio to the TNC (rig reciever audio) YELLOW
Pins 4 and 6 no connection.

VRM, what program are you going to use with the TNC?


WinLink is one, PSKMail http://pskmail.wikispaces.com/ is another. PSKmail is interesting because it's
layered on top of fldigi, and is multimode (ie you can initiate links using PSK250, THOR, MFSK16... not sure about Olivia )

I don't know if it actually forwards, it might be store-and-pull. It also offers an internet gateway (ie hit a page and it emails the page back to you
via HF.)

I might be able to e-mail you a copy of MFJCOM. It's a DOS program but works just fine. Any terminal program like Hyperterminal in windows (if your version of windows has it) will work. Once you get it hooked up to the rig and computer, set the DIP switches on the back of the TNC for TERMINAL (COM port) and radio speed. Start whatever COM program you have and then turn on the TNC. You should get the "sign on message" from the TNC. It will give you a command prompt (CMD:).
Type in MYCALL (yourcall) <enter>

The TNC will respond
MYCALL was MFJXXX now VRMN8TR
Then from the command prompt type
MCOM on <enter>
MALL on <enter>

These commands set the very basic parameters to start using packet.

I'm going to suggest you set the radio speed to 1200 baud at first, VHF/HF button to VHF, then tune the 706 to 144.39 FM and see if you can recieve any APRS packets. These will look mostly like gibberish, but there will be some human readable words/phrases/calls to see. This will confirm operation of the system.I'm assuming there is APRS traffic in your AO.

Switching to HF is just a matter of re-setting the DIP switches on tha TNC and the VHF/HF button.
I'm off to bed now..more tomorrow.

Does the yellow DCD L.E.D. light up when it hears a packet?
set these parameters..

Then from the command prompt type
MCOM on <enter> (MonitorCOMmands)
MALL on <enter> (MonitorALL)

This will turn off the "filters" so you see all packets regardless of if they are addressed to you or not.
ETA––
My PBBS is on and beaconing 14.105 LSB. Get yours recieving on VHF first, then switch it over to the HF settings (VHF/HF button to HF and reset the DIP switches for 300 radio baud.
Tuning the packet signals on HF is touchy. Make small adjustments to the VFO until the DCD LED lights with the packet bursts.
I'm off to work..yeah, I know it's Sunday. More this evening..

I switched radios to my Icom 728 for giggles.

I wired up a mic cable to the THC cable.
I can get the TNC to key the radio and send but I cant get the TNC to hear your beacon. (I can hear your beacon).
I dont know if your side will say I was trying to connect or not.

Just an observation here:
I went to USB and dialed up in freq. When I did that, the DCD light would come one at certain frequencies.
I dont know if that means anything but wanted to put it out there.

I THINK Im getting closer.

I downloaded a program called Winpack also.

Well, as before, thanks for the help/patience.

Im not "decoding" anything.

I ran to the shop and grabbed a plethora of cables (6 pin mini's).
I work for a non ferrous recycler and we have LOTS of computer wire.

I found one with 6 wires in it and Im going to try another DATA cable for the 706.

Wish me luck.

I just had an idea.
Instead of trying to permanently connect the wires before I get it figured out. Ill use
a bread board to do my configurations and then go from there.

NOW Im using my head huh?

Im making headway, I think.

Ive got the TNC to key the radio.

I need to figure out how to make the TNC hear the radio.

I takes time grasshopper...Let me know if you have success than we can give it go. My XP laptop for some unknown reason just froze up?
I am trying a Vista system with the serial to usb conversion, lets see how this works out.

Has your station been broadcasting for a while?
Ive got a real good signal on 14.105.
I need to match your baud rate? Correct?
