Hi, Normally all chargers have correct polarity. Neways,
Check this picture of the power plug.
http://www.coding4fun.net/images/ComputerControlledRCCarwithCamera_525E/CIMG01904.jpg

The outer metal surface is negative and the inner (hole) is positive. So, now you know which part (in your camera socket) is positive and negative.

:)

    Congratulations on your purchase of the Sima SUP-2 Universal Power Adapter. It

    can power digital cameras and other portable electronic devices requiring 3.3 / 4.2 / 5.0

    / 6.5 / 8.4 or 9.5V DC power. The SUP-2 can also provide power for other devices. It is

    fully regulated using high efficiency switching technology and features overload and

    short circuit protection. The SUP-2 comes with seven connectors to fit different digital

    cameras and other electronic devices. Additional connectors are available from Sima.

    This package Includes:

    1 AC adapter 7 Center pin positive connectors

    1 12V car lighter cord 1 SUP-2 This Manual

    Operation

    1. Set the output voltage switch, as illustrated in Fig. 1, to

    the desired output for your device. Choose from the

    following settings: 3.3 / 4.2 / 5.0 / 6.5 / 8.4 or 9.5 V.

    The SUP-2 comes with seven standard connectors. The

    connectors allow you to match the size and polarity of

    your device’s DC input jack. If your device requires other

    types of connectors, contact Sima customer service at

    800-345-7462.

    The connectors supplied with the SUP-2 are all set in a

    center pin positive alignment ( Fig. A) If your device

    requires a center pin negative power source (Fig. B)

    do not use this adapter.
    To determine the required

    current and correct polarity for your device, refer to the

    manufacturer’s instruction manual or specifications

    2. Select the appropriate connector and attach it to the output socket at the end of the

    output cord. The connectors are numbered as follows: 1, 2, 4, 5, 13, 14 & 17. To

    identify the correct connector for your camera, see the list of digital cameras on the

    reverse side of this sheet. If unsure, use the connector that fits the power jack of

    your camera. The three-pin connectors are designed to fit into

    the socket in only one position. Align the pins as shown at

    right in Fig. 2. Do not force.

    3. Insert the connector into the power jack on your portable device.

    4. Plug either the AC adapter or the car cigarette lighter cord

    into the SUP-2’s input power jack located at the top of the

    unit. Note: Do not plug the AC adapter or car cord

    directly into anything except the SUP-2.
    Next, plug the

    AC adapter (or car cord) into a standard AC wall outlet (or

    car lighter). The red power light on the SUP-2 should turn

    on. You can now operate your device.

    IMPORTANT:
    Your portable device must be rated between 3 - 10V DC and no more

    than 2100 mA of current to use the SUP-2. If the exact voltage for your device is not

    listed below and is less than 10V, you can try setting the voltage switch to the

    nearest voltage – use the lower setting first. If the device does not operate, disconnect

    the connector from the device, reset the voltage switch to the next higher setting

    and re-connect. Do not continue trying higher settings as they may result in

    damage to your device or the adapter.

    The SUP-2’s current (mA) must be equal to or greater than the current your portable

    device requires. Remember 1A = 1000mA, 0.5A = 500mA. Use the following chart

    to determine the output current from the SUP-2:

    Output Max. Output Max.

    Voltage Current Voltage Current

    3.3V = 2.1A 6.5V = 1.7A

    4.2V = 2.0A 8.4V = 1.6A

    5.0V = 1.9 A 9.5V = 1.5A

    Resetting the Adapter

    CAUTION
    : If the power light turns off, check the power source. If on, the output current may be

    beyond the AC adapter’s specifications and the overload protection has been activated.

    To reset the adapter:

    1. Disconnect the AC adapter from the AC outlet and the device you are powering. Wait 10 seconds.

    2. Plug the AC adapter into the AC outlet again. If the indicator remains off, there may be a problem

How do I connect my K7 to a 1394 socket


Hi,

Your Pentax K7 lacks firewire (1394) connectivity, so a connection to a fireware jack will not be possible without purchasing an inexpensive Firewire to USB adapter . From the manual:

Available Ports:

  • USB 2.0 hi-speed, AV out, HDMI out, DC in, cable switch, 3.5mm stereo microphone.
  • Video out: HD (1080i30, 720p30, 480p30), NTSC, PAL
  • Printer interfaces: n/a

You can connect a USB cable from the "PC/AV" on the camera to your computer's USB port with an appropriate cable to transfer image files for editing, etc. Additionally, you can send video directly to a TV with an appropriate cable via the camera's HDMI jack.

I hope this helps!

What voltage and polarity do the ACS-5 speakers require?


Computers always use DC voltage. Computer speakers receive DC voltage from the computer.
DC voltage has a Positive and Negative polarity.

In the power jack of the speaker, the Center pin is the Positive connection. The outer shell is the Negative connection.

Center hole of the DC adapter plug - Positive.
Outer shell of the DC adapter plug - Negative

Voltage 5 Volts DC.

I have a Sangean ATS 818cs portable radio but no 6v lead input


Yes you can use any 6 volt DC for your radio but the most IMPORTANT thing to remember is to connect the terminals in the correct direcction. First of all you can solder a red wire from the positve terminal of the battery and a black wire from the negative terminal of the battery. This must be connected to the source of your 6 volt battery.You can buy a good DC jack socket female to be fitted into the vacant spot of your radio and use a male jack to supply the DC. Only be carefully to see the polarity. To avoid any reversing of polarity use can even connect a diode in the forwarrd bias towards the positve terminal. This will prevent any wrong connection of polarity to damage your set. Helpful? Good day

I have a Casiotone MT70 made in 1984. How do I check the polarity as I need to get an AC Adaptor and don't want to damage the keyboard?


Here is how you might check the polarity of a 7.5 volt DC replacement adapter:

Put the 5 batteries into the unit and verify operation. NOW using a DC voltmeter measure the voltage from battery negative and meter negative connected and meter positive to the pin on the power jack. IF you see 7.5 volts positive, then the pin is the positive lead for the adapter.

If you see zero, then continue testing.

With the 5 batteries inserted, connect the positive meter lead to the positive of the stack of batteries. Now touch the negative meter lead to the pin.
If there is 7.5 volts there, then the pin is the negative lead for the adapter.

READ THESE INSTRUCTIONS CAREFULLY.

USUALLY the jack has a contact that disconnects the batteery when the plug with sleeve is inserted.. We are testing the jack without inserting a plug here so the plug should HAVE THE BATTERY VOLTAGE with correct polarity on the pin.

What is the ac polarity of a fujistsu lifebook c2330?


In household and commercial electronics 110-125 AC has no polarity unless there is a safety ground, in which case the green safety is connected to to the white wire via earth ground. Black is "hot" meaning if you touch it you will feel a shock because your body connects the circuit to ground. A laptop operates on DC power delivered from an AC-DC converter usually around 20 Volts dc and 3.5 Amps, and charges the battery as well. Polarity of your computer is positive tip meaning the fat part of the plug going into the jack is ground, or negative, and the center is positive. I hope this helps.

Dc jack


This is usually quite a tricky repair on laptops as you'll need to solder the new jack socket to the motherboard in the laptop.

If you cant get the original socket, you could get a chassis mounted socket, mount the socket onto the case where the old jack was and fix it in place with a nut. Then solder 2 pieces of wire from the socket to the motherboard.

Watch the polarity though, else you'll have a fried motherboard!!!
