Motorola PM400 Programming Problem

[KYQ1952]

The PM400 requires a jumper in the programming cable that the CDM/Maxtrac and ETC does not. I have made many of the cables and I know one goes to pin 3 of the RJ-45 and I think the other MIGHT go to pin 1. I will look in the AM and Post an update concerning this.......I have programmed at least 1000 of these in an entire state so I know this is the problem if you have the right PM400 software! In fact I have added a small switch to the cable to switch the jumper in and out so i can use the same cable.....I have a cable about 50ft long that I use on bulldozers on the top of truck beds!

Sorry Steve, I totally misread your post!

Jumpering Pins 1 and 3 is correct for the CM's & the PM's. I spent a very frantic night reading through old posts on batlabs to find the info. Finally found it in a post that was about 5 years old.

Neat trick with the long cables. I did the same here so I could use the Pro Series off an old XP desk top machine in the shop and still reach cars and trucks out in the service bay. (That was before the latest release, of course.)

Cheers!

Yes pin 1 and 3 tied together will allow a CDM/Maxtrac cable to program a PM400! Good Luck!

OK THANKS sorry im new here i bought a new cable i will c what happens

[BATTALION33]

I FIGURED IT OUT IT COST ME OVER $200.00 THOUGH I ENDED UP BUYING THE DISK FROM MOTOROLA R05.16 and the radio is a TKU (OCT OF 2009) MODEL AND THEY TOLD ME I NEEDED A ADAPTER TO PROGRAM IT BUT MY CABLE TURNED OUT TO BE OK ..

Hey guys i got it working i needed a newer version of the software which i got from motorola online . Radio turned out to be a 2009 model got it working but only gos to 470 not able to stretch it at all. Aftermarket cable works well (seperate from cdm)

So I'm left wondering... can you program both a CDM1250 and a PM400 using the same RKN4081C cable?

Re-read the thread arefully. Here are the highlights.

• The answer to your question is NO!

• Pins 1 & 3 must be jumpered together to program the CM & PM radios.

• If there is no voltage (+9.3vdc) applied to Pin 3, the CM or PM will not go into programming mode.

• They are not jumpered in the stock RKN4081C.

• Either the cable must be modified or an adapter built or purchased to use on the CM/PM radios.

I don't think I missed anything.

Thanks. I looked over the thread again and I think what I'm taking away is that you CAN use the ribless OEM RKN4081C cable to program a PM400 provided that you have the FKN8096B adapter. Did I get that right?

You are correct. That is exactly what Motorola wants you to do.

Or you can build an adapter for yourself for a lot less money. It is what I did. I had an RJ45 wall socket lying around, and a CAT-5 cable that was damaged. Jumper 1 & 3 and pass the other 6 straight through. Voila! Homebrew FKN8096B for pennies.

Still need the RKN4081 C, though.

Have always used the RKN4081 and FKN8096 flash adapter for programming PM400,CM200 and CM300.
