Can someone who has the programming cable, post detailed photos including the pins and were they attach to the radio?

 

I'll most likely buy the cable from a store if i cant find a way to rig something.

 

We all have the same problem....

I've got the kenwood cable stripped and so, but still can't figure out where to connect them on the radio :(

Sooner or later, we will find something.

Has anyone looked at thru which leads the Kenwood programming cable works -- thru the same as the headset or are they using different parts of the plug than the headset? If they're same as the headset, the following might be helpful.

 

I took the side-plate off and if you number the plugs on it clock-wise with the 1 being the plug at the notch, they go to these leads:

 

1 --> 4

2 --> 9

3 --> 9

4 --> 8

5 --> 11

 

Now I understand there might be a reason the company which made the programming cable released it with its own side-plate since it might have been needed to connect to some other leads, but since it's a Kenwood clone and if usually clones use the same leads we can just mathematically find the correct connection as we only need to use some combination of pins 4, 8, 9 and 11 on the radio.

 

Also, there's a piece of rubber which is covering the pins on the radio itself, if you remove that rubber cover you will expose easier connections to pins. BTW, how many leads are there going from the USB stick on the Kenwood programming cable?

One more thing -- I realize nobody wants to crack the cover on their expensive radio, but maybe we should set up the fund for one of us to order a new set and crack open an existing radio. If 10 more people chipped in 10 bucks each that would be enough. Or if 2 more people chipped in $35 each that would be enough too.

 

Anyone else wants to join in on the fun? Should I set up paypal donations collection fund?

I've connected RED cable with contact 4, BLACK to contact 9 and WHITE to contact 8.

 

When I plugged it into the computer it started to install some Serial to USB Drivers, but after that nothing..

What mode should the radio be set to?

Should it be turned on? Any special channel?

Any ideas? :)

Hi,

 

i have the same problem as all here in this thread and basing on my experience with other radios normally there should be a sequence to activate a programming mode, someting like "keep ptt pressed then power on the radio keeping it pressed untill you hear some beeps".

Once the radio is in programming mode then try to connect with the software to download the actual parameters and if this works all is done !

 

Another idea came to my mind looking at the original cable picture: maybe there is a bridge to be made somewhere in the pins to activate the prog. mode: i have read somewhere in the thread that someone had been so lucky to buy an original programming cable, maybe he (or her) can help all of us......

 

If you will do some trials please post your results, maybe we will find the right way.

 

Thank you a lot !

 

Federico

 

P.S.: which cable did you bought ?

I can't find any mention of it on the forums but I've just spotted a photo on RSOV's front page for a Vanaras 446Mhz PRR. Fingers crossed.

Any news on the Pin layout or is this still being treated like a state secret? I am ordering a radio and having an electrical engineer take a look at building the cable. He is pretty confident that it should not be a problem. If all is a success I will let you all know, I dont understand how after this much time...some of you folks that have the cable could not spend 1 minute of your time to help out your fellow Airsoft enthusiasts by simply providing a Pin out Spec. Although, from what my guy tells me there is more than just using the wires, there are resistors involved as well.

Yes I was also talking to Brooke about the schematic that he posted up. It is only a partial schematic from what I have been told by my friend. Once the radio is in his hands, he says he will be able to do it. There is also a chance that it can be programmed directly through the Lemo connection, witch would make thing nice. I will keep you posted on the success or failure, but as this is not a paid project it could be some weeks before I have any news. So you guys with a cable still have a chance to be nice!

To anyone who is in the EU.. how did you manage to import this PMR? Its not exactly CE certified is it?

 

Well, its not like many customs officers even know that it has to be CE-certified, and since when did start checking

all the cheap electronic stuff coming from china for a CE mark anyway. :-p

So has anyone made any progress building the programming cable for these? I'm getting desperate now -- I'm willing to either borrow the cable and pay shipping both ways or even send my radio and the channel file to be programmed by someone who has the cable. Please let me know.

Hi. Someone tested PTT Wireless button ? Mine working only in very short range...

 

Don't know for the replica Wireless PTT, but the real one only works at a arms length or about one meter away from the radio.

Thx for trying help.

 

My work only at 0.5 meter max, above this just turning Tx, and turning off repeatly.

PTT button on the radio works fine.

 

I wondering.. if it is right (?)

 

(sorry, for poor english :P)

That sounds right. That's roughly the intended range as per the real steel bowman PRR. It's meant to be on your rifle which I don't think is more than 50cm away from your radio.

No :( Range is too short to operate PTT placed on the gun. 0.5m was in wide open - nothing between button and radio (for example, no hand pusshing button like it was on the gun) :-/

Signal is to weak or something is wrong with radio/wireptt ? I need someone to compare mine :-/
