Wouxan KG-1000g plus faceplate data cable


Gnarlykaw

Question

Nine times….. all of them FAILED to work.  The best I have ever got was a power up, but stuck on sync data.  Even tried pass thru RJ45, and still failed.   YES, I swapped pi’s 5 and 7 on ONE connector…

  I have done dozens of RJ45 connectors for video cameras for alarms and have had zero problems making lines for these…

the original patch cord was defective, and I just thought I would try to make one…

tool operator error?   Blind old guy??

Anybody have any luck making one??

The Wouxun KG-1000G cable is not a standard straight through or crossover cable. Pins 5 and 7 are crossed.

Here is the pinout for the KG-1000G cable

  • 1 - 1
  • 2 - 2
  • 3 - 3
  • 4 - 4
  • 5 - 7
  • 6 - 6
  • 7 - 5
  • 8 - 8

I will suggest getting a cable tester for testing. Here is one on Amazon that will test 6 wire cables with RJ12 connectors and 8 wire cables with RJ45 connectors.

As noted by WRYZ926, the sequence is a bit difference. Definitely use a standard cable tester and couple the OEM cable to your new cable build for testing. The indicators should light up like a normal cable. FWIW, the extension I made took 6 tries before it was of sufficient quality. Hang in there. YOU CAN DO IT!

thought i would come back and give an update....

I ended up sending the radio back to BTWR, because i was convinced that the radio HAD a failure.  Sure enough, they tested it and found fault in the faceplate.  they warranted to unit, and the new one came two days ago.   YES, I have a plethora of different length data cables, all shielded, that work PERFECT!   The permanent install starts tomorrow...

Although, it appears that CHIRP has NO solid program for this radio, and im having some difficulty with the WOUXUN data cable....

Glad you found the problem, and that it was not you!

As for programming, make sure that the data cable is securely plugged into the side socket on the radio.   When you get it working,  their program is fine.  Be sure you download the one for the KG-1000+ version of the radio, not the older 'non +' one.

The manual description says to swap pins 5 and 7, but that is after flipping over the connector.  So if both ends are facing up with the strips facing you...

1-8, 2-7, 3-6, 4-5, 5-2, 6-3, 7-4, 8-1 

I had to draw it out because it made my head hurt a bit.... but I'm pretty sure that makes the cable uni-directional. Like you suggested, I'd do some testing long before sticking that in my hole radio.

Interesting... when I tested both the short and the extension cable.... it looks like they are wired 1-1 through 8-8 (like a standard ethernet cable) with just pins 5 + 7 flipped.  I also noticed that on my extension cable, the second pin is shorted.  So... it may work (depending on what pin 2 does), but I'm going to reach back to buy2wayradios to see if they can swap it out. (before I go through the suck task of taking apart half the interior of my vehicle to install it).

Yes, pin 2 is grounded in the short cable and I tried it with and without and it made no difference when you make your own cable. The only caveat is cable length.  It starts to loose packets/communications when you go longer than the supplied extension cable. We had to learn this one the hard way. I reached out to B2WR and they said there is no solution.  We are very bummed. Good luck

I found the same thing with pins 5 and 7 swapped. It was the same with the short cable and the extension cable. None of my cables showed Pin 2 shorted at all. I tested the short and extension cables on my KG-1000G and KG-1000G Plus.

That's also interesting.  The manual for the 1000G says to swap pins 2 & 4.

Because I'm visual.  I updated my graphic for the correct pinout for the 1000G Plus.

That has to be a power thing.  Even on regular CAT5, I don't think you are supposed to have any data loss until you go over 100 meters. (Way longer than the supplied cable).  If it's a voltage drop thing, maybe CAT 6 or CAT 7 would help?  That's why for POE, to maintain 12vdc at 100 meters, you inject 48vdc and let the device regulate whatever is left at the end of the run down to the needed 12vdc.  Given that, if you could identify the power pins, you could (in theory) cut those pins at the head, then inject that voltage on those pins closer to the face to get up to 100 meters.   

FYI, I'm not a professional IT guy, so this may work, or you try this and your face plate explodes.

I am going to trust my cable tester that I have used for years making network cables over a printed manual. Especially after testing cable for two KG-1000G radios.

I have been out of doing any type of network administration for some time so my memory might be off. But generally the maximum length of any CAT 5/6 cable is 300 feet/100 meters for computer networks.

PS; I'll stick to using actual cable testers to test my network/communication cables.

It's a lie, looking at the connector with the locking tab away from you and the end facing up it is the two pins on the right 5 and 7. And you only do it on one end of your patch cable. I remember reading that  manual paragraph over and over. I have physical knowledge of this and it works.  Disregard the un grounded #2 pin. It works either way. If you use shielded cable then you should see #2 is grounded(at both ends) on your network cable tester.

Ok copy that. I understand the 300 ft maximum on network cable. Also i used cat6. Your idea It is worth experimenting with. The head/display @60ft ccame on and was stuck on " reading......" so it had power.  Thats what lead me to packet loss verses power. I can also presume power is low and maybe the head cant generate the power to receive or transmit packets. We have 100's of these radios out there.

I wanted to note we use Chirp for all our kg-1000g's. They have support for the original and pro version.

There is no difference between different Ethernet cables with differing Cat labels. The ratings have to do with the capacitance and coupling between the pairs in the cable, which affect how well the cable handles data bits. In actual practice, a Cat 5 cable handles data up to 100 Mbps as well as a Cat 6. For extending a radio's faceplate from the radio body, a Cat 3 cable has all the capability needed. The distance limit, 100 meters, is based on the resistance of the wire to current flow.

It seems that everyone is assuming that Ethernet level digital signals are being carried between the head unit and the radio body. Do you know that is true?

No, I don't know what is carried on the cable. My best estimation is that the signals are a combination of analog (voice) from the microphone and either DTMF tones or digital codes from the keys. PTT is probably either voltage or ground to key the transmitter. Someone with an Oscope could breakout the wires and examine the signals. I don't have any test equipment more sophisticated than a VOM and SWR meter.

I agree with Box car , audio, put function, maybe even some can bus protocol or rs285. I am just learning about these  different protocols.

Is that for the Mic or the tethering cable? 

Steven (BTWR tech), said that was for the tethering (radio -> face) cable.  But after sleeping on it.... it looks more like a mic pinout.  And that image makes the 5-7 crossover even weirder.  I just emailed him again to verify if that is the Mic or Data cable pinout.
