The initial default hardware implementation for AppleTalk was a high-speed serial protocol known as LocalTalk that used the Macintosh's built-in RS-422 ports at 230. 4 kbit / s.

One common replacement for LocalTalk was PhoneNet, a 3rd party solution ( from a company called Farallon, now called Netopia ) that also used the RS-422 port and was indistinguishable from LocalTalk as far as Apple's LocalTalk port drivers were concerned, but ran over the two unused wires in standard four-wire phone cabling.

When the SCC's internal PLL was used to lock to the clock embedded in the LocalTalk serial data stream ( using its FM0 encoding method ) a divide-by-16 setting on the PLL yielded the fastest rate available, namely 230. 4 kbit / s.

The table below shows the name and purpose of the various pins in the GeoPort-enabled serial connector when used in GeoPort, RS-422 ( LocalTalk ) and RS-232 modes.

These included a port to attach floppy disk drives, two serial ports for devices such as printers and modems ( which could also be used to connect to a LocalTalk network ), an Apple Desktop Bus port to connect the keyboard and mouse, and composite and RGB video ports.

Early installations used mainly LocalTalk and more recently Ethernet but any physical medium could be used which could be directly or indirectly connected to an AppleShare server system.

Like LocalTalk, the theoretical maximum speed for data transfer was 230 kbit / s, and it is generally used in a daisy chain topology.

A similar solution was the 850 kbit / s DaynaTalk, a separate box which plugged in between the computer and a normal LocalTalk / PhoneNet box, and also offered as a PC expansion card that ran up to 1. 7 Mbit / s.

Based on the AppleTalk protocol stack, LocalTalk connected the LaserWriter to the Mac over an RS-422 serial port.

** LocalTalk compatible Local area network port

The topology was a bus: cables were daisy-chained from each connected machine to the next, up to the maximum of 32 permitted on any LocalTalk segment.

LocalTalk is a particular implementation of the physical layer of the AppleTalk networking system from Apple Computer.

The IIGS also supported booting from an AppleShare server, via the AppleTalk protocol, over LocalTalk cabling.

At 230. 4 kbit / s LocalTalk was slower than the Centronics PC parallel interface, but allowed several computers to share a single LaserWriter.

Several other similar systems also existed with even higher performance, but these often required special cabling that was incompatible with LocalTalk / PhoneNet, and also required patches to the networking stack that often caused problems.

With its release, AppleTalk Personal Network was renamed LocalTalk.

These included updates to EtherTalk and TokenTalk, AppleTalk software and LocalTalk hardware for the IBM PC, EtherTalk for Apple's A / UX operating system allowing it to use LaserPrinters and other network resources, and the Mac X. 25 and MacX products.

As with LocalTalk, a number of 3rd party adaptors quickly appeared.

Stanford University pioneered development of a system, MacIP, that allowed IP packets to be routed over LocalTalk networks with the support of a suitable " gateway " machine.

Each node dynamically chose its own node number, according to a protocol ( originally the LocalTalk Link Access Protocol LLAP and later the AppleTalk Address Resolution Protocol, AARP ) which handled contention between different nodes accidentally choosing the same number.

* Apple's LocalTalk implemented CSMA / CA on an electrical bus using a three-byte jamming signal.

Marathon network games can be played over AppleTalk Remote, LocalTalk, TokenTalk, Ethernet, and more recently, a LAN network or the Internet.

LANs were complex and expensive, so Apple developed its own networking scheme, LocalTalk.

The LaserWriter was also the first peripheral to use the LocalTalk connector and Apple ’ s unified round AppleTalk Connector Family, which allowed any variety of mechanical networking systems to be plugged into the ports on the computers or printers.

LocalTalk specifies a system of shielded twisted pair cabling, plugged into self-terminating transceivers, running at a rate of 230. 4 kbit / s.

The phased array is used for instance in optical communication as a wavelength-selective splitter.

The Laguna Seca edition includes a large adjustable splitter in the front, and a X-brace where the rear seats used to be, making it a 2-seater.

This greatly simplified the installation of combined voice and data wiring in countries that used registered jack connectors and American wiring practices for their phone service ( connecting both to the same cable was a simple matter of using a pin-pin RJ45 splitter or punching down the same wires to two ports ).

An additional photomultiplier system viewed a beam splitter in the optical path and was used as a star mapper – to monitor and determine the satellite attitude, and in the process to gather photometric and astrometric data of all stars down to about 11th magnitude.

It would be used with a chisel or splitter for a variety of purposes

Due to a flaw in the design, when two joysticks were used at the same time ( through the approved splitter ) they would interfere with each other.

By starting a cut with a dado and then raising the blade to leave a splitter tab of uncut wood, this type of kickback can be avoided, but raising the blade during a cut cannot be done unless anti-kickback hold downs are used, so it is safe to raise the blade with a free hand.

That is why it is used to form emitter-coupled amplifiers ( avoiding Miller effect ), phase splitter circuits ( obtaining two inverse voltages ), ECL gates and switches ( avoiding transistor saturation ), etc.

* Pellicle mirror, a thin plastic membrane which may be used as a beam splitter or protective cover in optical systems

A splitting maul also known as a block buster, block splitter or " Godevil ", is a heavy, long-handled axe used for splitting a piece of wood along its grain.

The splitter grew out of a much older pitch known as the forkball, which was used in the major leagues since the 1920s.

David Cone was famous for his splitter, used most often in the middle and later part of his career.

As such, a frequency splitter, or DSL filter, cannot be used to allow a telephone line to be shared by both an SHDSL service and a POTS service at the same time.

Later systems didn't build in the game software, used separately plugged in controllers, didn't take batteries, and typically required a special splitter box.

His next-most used pitch is a cutter ( 88 – 91 ), followed by a splitter ( 80 – 85 ).

Later versions used ECCS ( Electronically Concentrated Control System ) engine management, discarded the twelve tiny runners for six much larger ones ( though they retained twelve ports on the head, so there was a splitter plate ), and received a slightly larger turbocharger.

There were a few models with a tube phase splitter in them, but for the most part Music Man amplifiers used the faster responding common Grid, Cathode Coupled drive from a solid state front end that players characterized as " loud as hell ".

They are primarily used at modern roundabout intersections within the splitter islands ( a raised or painted area on the approach of a modern roundabout used to separate entering from exiting traffic, deflect and slow entering traffic, and provide storage space for pedestrians crossing the road in two stages ) and at the ends of pedestrian refuge islands, typically located at mid-block pedestrian crosswalks.

An image splitter was used in the TK-40 / 41 to direct the incoming light into three image orthicon tubes ( specially designed cathode ray tubes ) for recording moving pictures in the red, green, and blue component colors.

* A chain tool or chain splitter is used to ' break ' a chain, in order to remove it from a bike or remove links, or to put a chain back together.

For TDM-PON, a passive power splitter is used as the remote terminal.

* an image focusing system for reflex cameras where a beam splitter is used to generate two images where the subject is out of focus and one where it is in focus.
