Question about Addlogix (MD4-103) Networking Switch

2 cpu's one keyboard (adb)

Hello My question: I have two old macs and I would like to use my adb keyboard for both computers. I thought to buy an adb adapter (female/female), connect the keyboard (male) to one extreme, connect the switch cable to the other extreme and connect two adb cables (port A, port C) to the switch, one for each computer. Is this OK or are there some electrical considerations that I sould be aware of? I really appreciate your help, TIA, R

Yes and no. The good thing is this will work the bad thing is the possible droping of the driver connection which rarely happens, but it is a possibility. Also if the cables use mechanical switching there are galvanic issues that may occur (and opto-isolated switch is better). However this will work. This the basic functionality of the KVM switch.

I bought an old Mac Mini Intel Core 2 Duo, 2 GB Hard Drive, OS X Yosemite, with serial # C07CS2TPDD6H. What adapter cord could I use to connect it to an iBox C1752, TFT LCD Monitor?

That Mac has a hdmi port and a mini display port. The monitor has a saga port. So ether a hdmi-svga. Or miniDisplay port-svga.

Any usb keyboard will work. So any Mac keyboard newer than 12 years should be good, and newer pic keyboards will work. Beware of older keyboards that have round plugs. On macs these were ADB ports. On PC's, they used PS2 (ADB, ps2, usb are all different, you want the flat rectangle USB)

U.S. pc keyboards also have two modifier keys wired different than the U.S. Mac keyboards, but this can be adjusted in the system preferences. Can't say for non U.S. KBs. They are the windows/alt keys. Vs Opt/Command keys. That is, if you are soused to using a Mac, the key that is closest to the spacebar (command key) is applied by the second key over rather than the first. Again, this can be modified in the Sys Prefs.

How do I connect the mouse?

212
i am assuming you have a usb mouse and a PS2 connection on the computer. If this is the case then you need a female usb to ps2 mouse adapter
So that the mouse cable plugs into the USB female connection and the male ps/2 plug end goes int othe female ps2 port on the computer.
If this is the case you have the wrong converter the chester will convert a ps/2 on the mouse or keyboard to a usb on the back of the computer.. Can you tell us what sort of mouse you are trying to connect does the end of the cable have a usb plug on it a bit like the blue usb plug in your picture.
If this is the case then you need a female usb to ps2 mouse adapter
Google it and see the difference.

Wher can i buy a usb reciever for my wireless keyboard

Normally all wireless keyboards work with Bluetooth protocol.
Pls check it in your keyboard's specifications.

If it's so, then you can just buy a USB bluetooth adapter costing around 5$.
e.g. from ebay:

I would like to know what adapter (DVI to VGA Cable Adapter) I need to connect to a Macintosh G4. Thanks

Without knowing what Model Number of MAC G4 you're referring to, I can only give you generic information.

If your MAC G4 has a DVI port it is generally the female style.
The DVI connector on the adapter will need to be a male DVI style.

The VGA end of the adapter will be either male, or female. Most VGA connectors on a monitor cable have a male VGA end.

(The DVI end will have the pins sticking out on the adapter. The VGA end will have the socket holes)

Also stated as the monitor cable end will be a DVI male. The port {Connection} on the computer is a VGA female)

Example of a DVI male to VGA female adapter,

http://sewelldirect.com/dviaftovgam.asp

Barring that you need the other style of DVI to VGA adapter, (DVI female on the monitor cable, VGA male on the computer), this is an example,

[ Note* The newer VGA connectors are also known as an HD-15 connector.
More information on the Video Graphics Array connector,

http://en.wikipedia.org/wiki/VGA_connector

More information on the DVI connector styles, and the Digital Visual Interface technology,

http://en.wikipedia.org/wiki/Digital_Visual_Interface

If you should find all of this confusing, simply state in a Comment as to what connector is on the end of the monitor cable, and what connector is at the computer.

State whether the connectors are Male (Pins sticking out), or Female (Socket holes)

Older ArtZ II with ADB cable won't talk to my laptop

I'm thinking this is a Mac-only tablet. The ArtZ II for Windows came with an rs232 (old mouse) port at the end of the cable, in addition to a built-in spot where the power plug attaches.You didn't mention the power plug on yours, so the Mac version of the tablet must have the power routed in through the cable.

Short answer, the reason the light isn't coming on is because the tablet isn't receiving power. If you go get a cross-platform adapter card for plugging in Mac hardware on your HP, it *might* work.
