Casio PC Board Assembly

There is an older lady in our church who has a Casio CTK-555L keyboard. I purchased an ac adapter for her to use instead of buying batteries all the time. I found out that another lady had purchased an adapter but was probably the wrong one and when she was trying to get it to fit, it appears that she broke the connection on the keyboard. I have located the part that I think I need (Casio Part # 69270460) but before I order it I wanted to know if it just basically plugs in or is replacement more complex (ie. soldering different wires etc.)?

    Thanks Ginko for your input. I was told by PAC parts that the connection that the adapter plugs into is a part of the pc board assembly and though the lady with whom I spoke said she was not a service technician, it appeared that the board had plug in connectors and would be simple to replace. That part number is listed as PCB ASSY, SUB (MA2M) on their website.

I do not know what part is # 69270460, it does not come in my part list. if it is the power supply socket on your keyboard, then it should be quite an easy task, providing that you have experience in soldering electronics. Todo the job you will probably need Casio schematics and service manual for 555L.
This website ask to do a donation to charity and will send the schematics. Give them (or ask the ladies) proof of recent donation to charity.
Alternatively this website sells schematics and service manual for a price between $10 and $20.

How do i set up my linksys to my laptop using a modem

If your modem is not one of the hybrid modem/router that has dhcp built in then what you need is a router instead of a switch. Think of a switch as a 2way phone adapter which just splits the signal and allows you to plug more phones or in this case PC's in. The problem is, your modem will only accept and bind to one mac address (PC). Get a router, plug the modem into the wan port of the router, now the modem binds to the router, you plug your pc's into the ethernet ports, if you need additonal ports you could plug in your switch to one of the ethernet ports but these days most folks have wireless on their laptops or desktops. When you purchase a router get one that has G or N standard, then you can broadcast your internet and enjoy it without all the wires.

How To Check A Dead One ?

If you mean it's completely dead with no power, first check the AC adapter if this model uses one (I think it does). Then open the case and check for obvious things like bad solder joints at the adapter power jack or other places in the power supply. Look for visibly bad parts (burned resistors, capacitors with bulgy or split tops, etc.). Most of these devices have pretty simple power supplies: rectifier diodes, filter capacitors and a regulator or two. You should be able to follow the circuit on the board and see where the voltage is missing.

If the problem is anything other than a simple part failure in the power supply, then don't waste more time trying to repair it. You won't have any luck finding parts or service information, and replacement cost is low enough to make it uneconomical to put much effort into the repair.

The connection on the rear of the hub should go to a USB connection on the laptop, not a PS/2 connection. A PS/2 to USB adapter is used to connect a PS/2 keyboard or mouse to a USB connection.

Power supply for Targus 4 hub usb 2

Most USB hubs do not need an external power supply, except when a connected USB device draws more power than the computer/laptop USB port can supply. In this case an external power supply will need to be connected to the USB hub.
Normally this would be a 5 volt power supply, but make sure the polarity on the connector matches the power connector on the hub, check the label on the hub, sometimes it states to power requirements of the hub as well as the polarity on the connector. Normally the pin on the hub's power connector is positive (ie. +5V)

It would be possible to do this if the camera is actually using 802.11b (or g) ethernet and if the camera can be configured with an IP address. The specifications listing for your camera should provide the answer. There are other transmission methods that use 2.4gHz, so it's possible that the camera is not compatible with the wireless adapter on the computer.

If you determine that the camera is using 802.11b, you may need to run the wireless adapter on your computer in "ad hoc" mode in order to communicate with with the camera, unless you have a wireless router or access point.
