I have obtained a Kantronics KAM TNC. But I am unable to find any documentation or a pinout for this device. I would love to get it on the air, and I have the software, just not the means to figure out how to connect it to my rig, and computer. My question is, does anyone have the users manual, pinout, and command set for this tnc? Can someone email me this info, or point my to the site that maybe would have it? This is not a KAM+ or anything else but the White KAM TNC. Please help..

The manual(s) for the original KAM are common to the KAM, KPC-4, KPC-2400, KPC-2, and KPC-1.

Do you need just the connections of the whole bundle. It totals about 200 pages (double sided,) so it's not practical to scan and send it all via e-mail.
Let me know what you need and I'll try to help.

just commands and the rig wiring pinout, the cable for the computer is easy.
Thanks

Check K4ABT's site. He used to have a lot of TNC interconnection data online...

Commands manual still comes to over 80 pages; and the installation manual is over 50 pages (most pages are importent install and adjustment info;) far too much to e-mail.

There are a lot of "options" to setting up the KAM with internal jumpers, so it's difficult to pin the info down to a page or two.

Be careful with the serial cable from the computer. Although not normally used in standard RS-232c interconnects, pin 25 is internally connected to + 12 Volts in the KAM.

. On the DB-9 Connector: (VHF Port.)

Pins 1,3,5, and 6 MUST be connected:

1 AFSK OUT: audio signal TO radioo microphone input
2. Squench line; not normally used.
3. PTT Line. Grounded by TNC to transmit
4. Same as pin 5
5. Audio INTO TNC, such as from radio speaker line. Should be around 50 mV max.
6. Ground/shield
7. N/C
8. Same as Pin 6
9. Ground, same as Pin 6.

On the 8 Pin DIN Connector: (KAM HF Port.)

Pins 1,2,3, and 6 must be connected.

1. AFSK Audio out to radio mic input.
2. Ground/shield
3. PTT. Grounded by TNC to transmit
4. Connection for a CW Key
5. FSK for radios with FSK keying inputs/RTTY
6. Audio into TNC, from radio speaker line. (Same restrictions as above)
7. Not specified
8. XCD for squelch operation of radio.

The next 25 pages or so describe the adjustments to the inputs and outputs for proper operation. Unfortunately, there's no way to summarize it all here; the original KAM was NOT "Plug and Play;" ithe manual includes details for hooking up several different types of computers, including such dinosaurs (by current standards) as the TRS-80 and Atari models, as well as computers that used a "standard" RS-232c connection, such as the IBM PC.

Let me know if that helps.

Good luck.

How about the manufacturer's website?

The old KAM (and the Plus variant) pinout isn't the same as the KAM98...

That MAY be helpful, but there are CONSIDERABLE wiring and circuit differences between the KAM'98 and the original KAM, which is apparently what he has. (Such as pin 25 on the DB25 being HOT with 12 Volts in the original KAM, but not in the KAM'98.)
The original manual is no longer available at the Kantronics site, nor is it supported any longer. The schematic is also considerably different from the original.

The original documentation consisted of three manuals; an Installation Manual, a Commands Manual, and an Operations Manual.

Ok, well, I think I have the original KAM. It is white, and the manual the was sent to me of the 98' has the same connectors on the back. All I know is that it says KAM on the front and allmode. I am assuming that it is the original KAM. So, that leaves me to figure out what I have to do. The VHF Connector if 9pin, the HF is 8pin round, and the computer is 25pin 232. So, thanks guys for the help, I guess I have to ponder what to do next.

Dee,
Thanks for the references. I don;t have all of those.

Just FYI, there are significant changes in wiring and circuit design between the KAM, KAM+, and KAM'98, and whatever model (KAM XL, perhaps?) may be the latest or current model, so this IS one case where caution is necessary. the manual(s) I have came with a 2nd hand (perhaps third hand?) KPC-2; the original models of KAM, KPC-1, KPC-2, KPC-4, and KPC-2400 all shipped with the same manuals, which duly noted differences in each model. But through model changes, Kantronics changes some features and wiring options; to use the KPC-2 for home station use, I had to make up a special cable (and label it prominently) seperate from the cable I use for portable use with my KPC-3.

While I COULD put the manual on a CD, (as suggested by one of the references,) I don't have a working scanner at the moment (thanks to Microshaft's XP AND Epson's Plug and Pray compatibility) it would take an inordinate amount of time to scan almost 200 pages (double sided) at a usable resolution. And it's far too much to send via e-mail; with ISP limits, it would take nearly 2-3 months to send the whole manual.

MAybe there's a further on-line resource (such as mods.dk) that will have the manual for the original KAM available, but unfortunately, Kantronics doesn't archive their old manuals.

I tried to provide the important wiring specs, but that's only a starting point for the original KAM, as there are many options and adjustments to be made.
Now the easy part would be if the original owner had already set up the TNC for normal operation, and only slight tweaks are necessary, and I'll be glad to pass on any info in the manuals.
