Q: What is the difference between wdz cable and WDZN cable?: In accordance with the requirements of the general requirements of the installation of the switch installation height is 1300mm, the socket is 300mm, air conditioning socket is 1800 ~ 2200mm; wall in accordance with the norms is not allowed to take the horizontal pipeline, so the conventional approach is vertical inside the floor of the pipe is near run.

Q: I just bought a new motherboard and it had a 24 pin power thingy, my power supply was only a 20 pin. After looking at my manual it said I was able to do that if I aligned them a specific way. After that PC turns on, the lights turn on, hard drives turn on, and everything else. the thing is the screen stays black and says no signal.I was looking on the motherboard and there is a 4 pin ATX12V1, but there is no such cable that comes out of my power supply. I think the reason the screen stays blank is because it said that was used to power the CPU. What can I do since I do not have a ATX12V1 cable that connects to my motherboard?The only cables that come out of my pwr supply are for the IDE and floppy.: If your power supply lacks the 4-pin connector, then you're probably going to need a new one. If your power supply has a 20+4-pin setup, then you should be able to use that however. The 4-pin can snap together with the 20-pin connector sometimes to make a 24-pin, but if it's not there altogether and your computer won't power on, then you will need a different power supply with the proper connector.

Q: Okay so I'm production manager for a play in Oxford and I need to have a giant cardboard box drop from the ceiling triggered by an actor with a remote control on stage.I've found a rather nice electromagnet which should do the job which is triggered by a 9V battery. The trigger is an IR unit I'm building which finishes with a relay. The question is can I use a sound XLR cable as the wires in my circuit between the battery with the IR unit and the electromagnet?i.e.Electromagnet -----XLR-----gt; battery -------XLR-----gt; IR unitStandard XLR's do have 3 cables in and surely I only need 2 to complete the circuit.The only reason I'm thinking about using XLRs is that I'm not sure of the distance between things yet and I have plenty of XLRs in many different lengths.Any ideas?: This is done a lot in professional broadcast, except we use 4 pin xlr connectors to prevent inadvertant connection of DC to the audio system. Generally this is to power cameras or portable recorders requiring 12 volts at one or two amps.

Q: Hi everyone, I recently purchased a PS3 used not slim and am having a tough time with it. For one, I don't even know how to charge my four red dot blinking controller and turn on the ps3. I'm wondering since I got everything hooked up but still not even a red dot on the ps3 when I put in the power cable at the end there is that thing with the three things sticking out, where do I put that? Like a place where I charge my phone? I think that's why I'm having problems. Thanks.: ok. the PS3 uses a standard 3 prong plug, similar to what your PC would use. plug that in, and then into the wall. older PS3's also have a power switch right above the power cord. you have to turn the system on here. after you filp the switch, the PS3 enters standby mode. on to your controller you should have gotten a very short usb cable. the larger end plugs into the system.the smaller into the controller. push the PS button on the center of your controller to sync it. it should go from 4 flashing lights to one. then, it should steady flash position 1 to show that it is charging. one it is charged, or when the usb cable is removed, you should get a steady light. no flashes.

Q: I'm only asking this on here out of interest, this is not homework. I want to know how to calculate exact distances between to poles connected at the top by a cable. The length or height of the objects are not important to me, but if you must use an example please do so. So I want to know what formulas to use, what variables in those formulas mean, and how the slope of the cable will affect the distance. For example, if two poles have a distance between them of 0, and the cable extends 100, it would not mean that the drop of the cable (called a catenary?) would be 50, (it's misleading because you would think that since the distance between the two poles is 0, the cable would drop 50 and rise 50. But this is not taking into account the slope it has to take at the bottom of the catenary. It must lose some drop (perhaps to 48 or 49) in order to bend and rise back up...I want this out of my head, it's bugging me that I can't figure it out.: So you want the length along the cable? I honestly don't know how to compute the arc length of a catenary, but I'm sure that the power company knows how to do it because they need to know how much cable it will take to string up a whole line of poles. Your example doesn't work only because you impose a physically impossible constraint (zero distance between the poles - the poles have no thickness) and then try to impose physical reality (the cable can't bend instantaneously) on the problem. In the physically unrealizable problem, yes the cable does drop 50 ft because it is infinitely bendable. You're dealing with hyperbolic sines and cosines. Good luck

Q: I want to switch to cable phone (indeed, that Triple play service offered by companies as Optimum or Time Warner). When power fails, you dont?expect to have Cable TV or internet, but phone service is different. You really need it all the time. Some people told me outages affect cable phone service. I?m very concerned because some neighborhoods in my city have had blackouts recently.: I specifically put that question to my cable provider a few months ago. This was the official answer Quoted: ----------------------- Hello Jeff. Thank you for your email. The answer to your query is surrounded by a few variables, the main one being your proximity to the ‘node’ that your Internet service feeds off. In the event of a neighbourhood-wide power outage, our “nodes” are equipped by back-up batteries that may be able to supply the required signals for the modem to receive and transmit, though limited in duration. But as with any supposedly fool-proof system, there always exists the possibility of fortuitous failure. Please let us know if we can be of further assistance. Bob. Rep. no. 2597. E-Services Calgary, Telephone: 310-SHAW, Shaw Communications Inc. --------------------- So, in short, they do have battery backup for Internet on the local nodes... but for how long it will last is unknown and not guaranteed. That said, I am currently only using cable Internet to transport my VoIP services. I pulled the plug on my local telco, months ago. I have my cable modem, router, VoIP ATA adapter, and cordless phones connected to a battery-backed-up UPS power supply. But, these are all only temporary backup solutions. If you feel too nervous about not having phone or 911 service during a power outage... then, don't do it. Or, get a cell as your emergency backup comms.

Q: This is all I got in my PC, where is it?: it's just connected to the motherboard so find the hard drive, follow the cords to the mobo and one of those is it

Q: I got a free graphics card from my cousin and my computer only has the SATA slots for graphic cards and the one he gave me has the 4 Pin cable. Is there anyway to get it converted or any cables that can go from 4 Pin to sata? I wanna see how this graphics card goes when its working fully.: Check okorder ... I was flat out unable to find a SATA to 6-pin cable. To put it bluntly, I'm surprised the card works at all without that addition power line.

Q: So, recently i purchased a new graphic card and it requires two 6 Pin PCI Express Power Cables. My current power supply generates 650W and only has 1 six pin PCI express power cable. Im at a loss to what to do now. Do i purchase a new power supply that has more pci express cables? Or do i open it up and add a new cable? Thanks if you can take the time to answer my question.: you can purchase a molex to 6 pin pci express power adapter, this will fix the problem. This solution will work only if you have a spare molex connector you are not using Forget about what that other person said, that your power supply isn't big enough. 650w is more than enough to power a mid to high range graphics card

Q: I never expected this problem,but I have an HP with a liteon power supply.The thing has these weird clips on the power cables that go into the hard drive.How do I free the hard drive power cables? I have to put in a new power supply for my video card.: SATA just pulls out.. actually so does molex connectors (for IDE drives).. just very tough sometimes to get them out. If its black and kinda thin, then its probably SATA and they should just pull straight out.
