Certain non-PC-compatible systems (like the Radio Shack Color Computer) did actually use floppies without the cable twist, but required manually setting the jumpers, and could indeed use four drives at once. It turned out to be hardwired for A and the original computer used a normal cable, but had the signals twisted on the motherboard itself! They're both hard-wired drive Bs that listen to their select B pin, but for one drive we connected the select A pin to its select B so the motherboard can control it through the select A bus. Let's say both drives are hard-wired to be drive B. Now we don't have to setup them, but they both listened to the select B signal, while the motherboard would still want to send a signal to select A to select drive A. Here comes the twist! While this hack allows for the end user to not have to mess with jumpers, it also restricts the system to two floppy drives.

To prevent interference of signals, the frequency band is divided into two sections. Now the drive before the twist will work as a drive B listening to select B signals, while the drive after the twist will work as drive A listening to select A signals. In order for you to be able to control your device (like the TV), your remote and TV must work on the same frequency. Dual Band typically is able to extend IR for the most common products like Blu Ray players and projectors, and if it has RC-MM protocol then it should be able to control majority of cable boxes. Imagine you have just built your dream theater with the latest cable box, a new Blu Ray player, and a great sound system. Problem: since you moved your devices, your remote isn’t able to control your cable box, your Blu Ray player, or your great sound system. Typically, Single Band frequencies are only 33-43 kHz which works with most DVD and Blu Ray Players. All are outputs on the floppy controller and inputs on the drives.

The cable twist allows both floppy drives to be configured identically (for drive selection) when installed (for manufacturing convenience), yet operationally, can be uniquely selected as either the first drive or the second drive based on cable position. The drive before the twist will be drive B while the one on the end will be A. This way, there is no need to "configure" the drives which drive (A or B) are they going to be and what they should listen to. Cable types that are appropriate for DMX512 usage will have a nominal characteristic impedance of 120 Ω. Older installations used the RG-59 cable before the implantation of the RG-6 cable. Theft: the high scrap value of copper and the unguarded, remote installations make overhead cables an attractive target for scrap metal thieves. The term is also used for inductors in radio antennas, or between the antenna and its feedline, to make an electrically short antenna resonant at its operating frequency.

If you want to make sure your thermostat is hooked up correctly the first time and avoid any risk of damaging your system or new thermostat, you can trust the technicians at Malek Service Company to install a new C-wire and get your HVAC system up and running in no time. Obviously, you don’t want it all directly under your TV because it is too clunky and the wires are always messy. The IRQ lines are typically configurable in the hardware as well. Video teleconferencing involves connections among many parties, communicating voice, video, as well as data. Networks that use cable modems on standard cable television infrastructure are called broadband to indicate the wide range of frequencies that can include multiple data users as well as traditional television channels on the same cable. Only apps that are supported by CarPlay will appear on your display. The next time you connect your iPhone to CarPlay, the new order of your apps should appear on the display.
