Can i transmit +12v through CAT cables?

Here are the pinouts for the 4 wire and 6 wire D104 mics. they were great microphones back in the 1980s. I used to have one on my Ten-Tac HF ham radio.

Astatic (4 wire) Astatic (6 wire)
1- Shield 1- Shield & Blue
2- White 2- White
3- Red 3- Red
4- Black 4- Black
Yellow NC

you just need to know what the pin out is for your 10M Radio. here is what each pin is
4 WIRE MIC CABLE
Pin Number
1 Audio Shield
2 Audio Lead
3 Transmit Control
4 Receive Control
here is the manual.

RS232 and RS485 communications The PDQ Single Board Computer (SBC) has two asynchronous serial communications ports named Serial1 and Serial2. Each serial port can be configured for the RS232 or RS485 protocol, and runs at standard baud rates up to 115,200 bits per second. The default baud rate after a factory cleanup is 115200 baud. The Serial ports are implemented by the dual on-chip hardware UARTs (Universal Asynchronous Receiver/Transmitters) on the Freescale 9S12(HCS12) microcontroller.

Each UART (sometimes referred to as a "USART") controls the serial-to-parallel and parallel-to-serial conversion and performs all of the timing functions necessary for one asynchronous serial communications link. They translate the bit-by-bit data on the serial cable into bytes of data that can be interpreted by the operating system or by your application program. The communications is asynchronous because no synchronizing clock signal is transmitted along with the data. Rather, the UART deduces the correct time to sample the incoming signal based on the start and stop bits in the signal itself.

The Serial1 and Serial2 ports have identical communications capabilities, although more of the Serial1 signals (both RS232 and RS485) are made available on the Docking Panels headers and connectors. After a factory cleanup, Serial1 is the default serial port for program development and downloading. In a finished instrument, either or both channels can be used to communicate with other serial devices, or with other computers and/or terminals using RS232 or RS485. Having a second serial port is also handy for system debugging. Since both channels can operate simultaneously and independently, serial debugging can be performed while the application program is

You can see if the wire is made corresponding to the USB 1.x/2.0 standard. (All USB cables should follow the standard, but many manufacturers don't respect this and use whatever cables they get cheap.)
The Pin-out and wire colors can be found here:

1 VBUS Red (or orange) +5V
2 White (or gold) Data?

Hope this helps!

I have two articles on this, neither of which correspond to what I said in another answer.
Dell use or used to use a non standard pin out (so it will depend was made by AVC especially for Dells)
In the standard pin out the black wire is 0V, the next often yellow is +V (12V for your fan) the third one is speed sense, and the final one is speed control (you search the internet under 4-pin fan pin-out to be more confident.)
Two article are
http://www.formfactors.org/developer%5Cspecs%5CREV1_2_Public.pdf (section 4.1.6)
and
http://www.setiusa.us/showthread.php?2480-PWM-Fan-Pinouts-Industry-Standard-amp-Dell-configurations the picture drom the second article I reproduce (without permission).
To be certain consult your m/b manual which should all the pin assignmens on your m/b, or you can try to measure the voltage between 0V and the second pin to verify that it is +12V in your case (it may be lower or as high as 13.2V)

the standard colours for CAT5(e) or CAT6 ethernet cable are:

green, green stripe
blue, blue stripe
orange, orang stripe
brown, brown stripe

the typical setup for an ethernet connection in an RJ45 (the crystal end with the connection tab towards you) is

1 green stripe
2 green
3 orange stripe
4 blue
5 blue stripe
6 orange
7 brown stripe
8 brown

Wires 1 & 2 are used to transmit data from the PC to the router/modem (TX) and wires 3 & 6 are used to recieve information from the modem/router (RX). in this fasion, information flows along one pair or another and is expected to arrive at that pinout. the router/hub/modem takes care of the transition to the next cable or out to the internet.

In a crossover cable ONE end is configured as above, but the colours for wires 1, 2, 3, and 6 are exchanged so that when no hardware is between the two PCs/components the signal is transmited at wire 1 & 2 and recieved on pins 3 & 6 on the other system/component. the other colours are placed for backward compatibilitiy and other applications, such as power over ethernet.



following the standard above allows anybody familiar with RJ45 connections repair a connection with a standard colour code and pattern without having to see the other end. If you know you need to replace one end of a patch cable, you use the standard termination.

The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T / 1000BASE-TX (Gigabit Ethernet). It is expected to suit the 10GBASE-T (10Gigabit Ethernet) standard, although with limitations on length if unshielded Cat 6 cable is used. Category 6 cable can be identified by the printing on the side of the cable sheath.

Cat5e is suitable for 10/100/1000baseT ethernet for 100 meters, when properly installed.
Cat 6 is also good for 10 gig ethernet for 37 meters, but that is pretty short, unless just in a server room.
There is no Cat 6e, but Cat 6A will be good for 10/100/1000/10GbaseT ethernet for 100 meters.
Unshielded Twisted Pair has no ground shield around the wires. It is the standard in the US, where most network standards were defined. There are extensions to the standards to allow for the more common in Europe, Shielded Twisted Pair.
Some Cat-6 cables are too large and may be difficult to attach to 8P8C connectors without a special modular piece and are technically not standard compliant. If components of the various cable standards are intermixed, the performance of the signal path will be limited to that of the lowest category. The maximum allowed length of a Cat-6 cable is 100 meters (330 ft) when used for 10/100/1000baseT and 37 meters (120 ft) when used for 10GbaseT. This applies for UTP cables only. Shielded Cat 6 and Cat 7 cables are capable of 100m.....sodeep

What I was told through the mfg. was:
pins 1,8 =NC
pins 2,7= Chassis Ground
Pin 3= TX-
Pin 4= TX+
Pin 5= RX-
Pin 6= RX+

This would actually be a RJ45 (8pin) but uses the 6 pin cable and only 4 com wires.
Evidentally there is no standard for the pin usages for serial communications with RJ connectors. So this information might not be valid for other equipment.

http://www.ertyu.org/steven_nikkel/ethernetcables.html

this link covers proper pinout for cat 5 cabling. (RJ45). A phone line is RJ11. You can run ethernet cable through a wall and terminate it at a wall plate designed for ethernet (not a standard phone wall plate). You can't use the RJ11 cable currently in the walls for ethernet.

Looking at the connector, there are 3 rows of pins.
Starting with the first row closest to the alignment mark:
[Power On],[Center Speaker],[Sub Woofer]
[Surround Right],[Speaker Ground],[Surround Left]
[Right],[Left]

If you are trying to connect two JVC units, you will need an 8-pin cable that has the SAME pins connected on each side. You will need to test this using a multimeter set to ohms or 'connectivity'.
There are other 8-pin cables out there like the one for apple networking, but they use a crossover pinout where pin 1 on one end = pin 3 on the other end. This is bad. JVC needs pin 1 to = pin 1.

This is a standard connector/pinout setup that JVC uses, so connecting a TH-C3 to a TH-C50 works fine. There is a bunch of intermixing that you can get away with. The only thing to keep an eye on is the power in watts that one unit sends and the other recieves. Worst case is that the speakers are quiter than expected or that you can turn the volume up so high that it can damage the speakers. In all cases, you should get desired volume somewhere on the dial.

If you are trying to wire the speaker set custom, then you will need to take note that an '8-pin' connector is actually a 9-wire connector. Along with the above pinout, you will need to add Case Ground, which is the metal circle that surrounds the pins. To make the speakers turn on, you will need to apply 12v to the Power On pin and ground the 12v source to the Case Ground outer ring.
The system takes 3 to 4 seconds to fully turn on after this connection is made. Speakers should be wired using the center pin for speaker ground and each other pin respectful to each speaker.
