Posted: Mon Jun 13, 2011 0:16 Post subject: CA-42 Cable Not Recognized
I have Win 7 x64. Installed the driver and utility from the Serial Recovery Wiki.
Going of another thread here I suspect that the wires in the cable are as follows:
Red-3.3v
Black-Ground
Blue-Rx
White-Tx
Yellow-not used
However the cable itself does not provide any power so I used the phone splitter method I found here. Hooked up the red cable to match up to the 3V3 pad on the router for power and twisted the blue and white just to test out the prolific drivers from the wiki. I tried the USB device viewer but neither it or windows seems to think there is a connection. I spent almost 2 whole days trying to read information to get this working and its not working. Can some one help me out here?

There is no reason to 'suspect' nor should you use the colours from some other thread. The colours of the wires are completely arbitrary. Read the wiki on serial recovery, and note the picture with the proper pinouts from the end of the connector that you cut off.

Well i have a hard time cracking open the end piece, is it possible to diagnose the wires with a multi-meter and how so? Never used one before. I know its been said you can find the ground by measuring the ohms with a multimeter set to 220 OHM. I measured all the wires. Black is the only wire to give a reading, and when i touch the red wire, and hold it to the positive lead my Win 7 PC actually recognized the cable. In my uneducated guess, I believe this means the colors listed above are correct.

You don't have to break open the end piece. Check for continuity with a multimeter between the end that you cut off and each of the wires on the cut off piece. Then compare the wire colour to the picture linked to in the wiki. That will tell you which each wire is for, and which is tx, rx, and ground. You can google how to use a multimeter.

How else can you tell which wire runs to which pin if you dont crack open the end? If I understand, your saying simply combine the wires back together, and test the pins, but again how is this of use? Isnt it much easier to simply test the wires?

Its not using it in general, its using it to determine the rx and tx wires which google is not offering much help.

You should have cut it off leaving enough wire so that you could test which colour wire goes to each terminal in the wide flat end. Then, once you know which goes to tx, which goes to rx, and which goes to ground, you will know where to attach each wire colour on your router.
If you try doing it from the computer end of the cable, how are you going to tell which signal is which and what the values are supposed to be?
You DID read the wiki AND look at the linked pinout picture, right?

Reading and comprehending are two different things. I have read it over and over and over.

Well, I am just guessing but test each wire. If you ground out the negative prong of the meter, and tap the ground wire, you get no voltage reading. The multimeter is will provide power and then give a 3.3V reading on the power wire. All thats left is finding rx,tx and the extra useless wire.

Wrong unfortunately, the multimeter does NOT provide power.
To test the cable, you have to plug it into the USB port of the computer.
You DO NOT need drivers to test power.
Pick one of the wires and attach the black multimeter lead to it.
Touch the red multimeter lead to the other wires one at a time.
If there is no signal, then you may be on the RX line.
Find the combo that shows +3V or -3V
If it shows +3 volts, then the red multimeter is touching the TX line
and the black multimeter is touching the ground line.
That leaves your other line as RX.
If you have 4 lines to test, have to guess at RX and unused line.
But to test these, you HAVE to plug that CA-42 into a live USB port.
And you can use a USB hub if you want also, as long as its powered.

No, red could be touching VCC+, which will fry the serial port if you connect VCC to rx/tx. It is best to follow the terminals back from the wide end. If that is beyond your abilities, then you likely should not mess with it.

I think you misunderstood me. The cable does not gain power from the USB port alone. It needs to have something on the other end to complete the circuit.

How else do you think I got Windows to recognize the device when I held the red wire to the positive lead of the multimeter.
Quote:

5 wires. Like I said, power,ground,tx,rx, and unused.
One question remains, am I measuring with DC or OHMS? Which setting should I use? 20 OHMS? Does my test above mean anything at all? I am referring to the test that cause windows to pick up the cable. No one has cleared that up.

All these USB to serial cables have a chip inside them.
So just plugging it in, without the other end hooked up to anything, just means its a good cable.
You still have to determine what wire is what.
And no, there is no SET color coding - manufacturers choose whatever they want.
------------
If you are measuring voltages - use DC - and use the 20 v DC range
If you are measuring continuity - use the lowest OHM setting
Continuity means point A to point B is the same wire.
So when you touch the red multimeter to 1 wire, and the black multimeter
to one of the USB jack ends, you should see 0 Ohm or hear a Beep
That means you have the same wire.

I have to determine wire is which. Isnt painfully obvious this is what my questions are in reference to?
There is no set color coding. Thats exactly what I just said. I asked what good the link you originally provided does. If there is no set color code, then the fact it says red is 5+V is useless right?

Now we are getting some where, sort of, but like I said, I accidentally demolished the phone end of the cable trying to take it apart, so this methods out of the question. Now if only the wiki had stated it like this, I would have understood the relevance of the pins. Since the pins got demolished, I was thinking the wires could be diagnosed like I said with one end in the USB port because they should give off power anyways when connected to the USB port and tapped to the multimeter.
I was thinking if providing power to the red wire caused the cable to be recognized, then this must be the 3.3V because the cable wouldnt be recognized with out power running through it.
