Palm Multi-Connector

Palm Multi-Connector is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Palm Multi-Connector rather than just read about it. In short: The Palm Multi-Connector (also Athena Connector) is a power, audio and data interface connector designed by Palm, Inc. Use The connector is used by: LifeDrive, Tungsten E2, Tungsten T5, Treo 650, Treo 680, Treo 700p, Treo 750, Treo 755p, Palm TX, Palm Centro.

Key takeaways

Palm Multi-Connector belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Palm Multi-Connector to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Palm Multi-Connector from memory before moving on to harder problems.

Reference excerpt

The Palm Multi-Connector (also Athena Connector) is a power, audio and data interface connector designed by Palm, Inc.

Use The connector is used by: LifeDrive, Tungsten E2, Tungsten T5, Treo 650, Treo 680, Treo 700p, Treo 750, Treo 755p, Palm TX, Palm Centro.

Changes Palm, Inc. has changed the connectors it uses over time:

some early models used model-specific connectors or Palm Serial. some models connected via Palm Universal Connector (Older Standard for Palm Handhelds, circa 2001-2004) some machines used a standard Mini USB (Some Low-Budget Handhelds) some machines used a Multi-Connector (Newer standard for palmOne and Palm Handhelds) The Connector can be used to charge the device, transfer data to a computer, HotSync, and play audio. It is the new standard to replace the previous Palm Universal Connector, which performed similar functions but did not have an audio output capability. This port has also been used to connect to an external microphone or to GPS units

Specification The connector is divided in two sections: the longer one has thirteen pins numbered from right to left (5 to 17); the shorter one has three pins, on the left (3), top (2) and right (1). The cable shield connectors (4,18) are located on each side of the thirteen pins.

Pins 10 and 11 have TTL levels and cannot be directly connected to the RS-232 port.

Opinion The Multi-Connector has received criticism from users who were familiar with previous connectors such as the Universal Connector. Users have been frustrated with the requirement to replace their Universal Connector cables, cradles, keyboards, sleds, and attachments as they have become incompatible. Another criticism is that the connector is fiddly, harder to remove and feels fragile. All that is needed to charge the Treo is to connect +5 V to VDOCK and 0 V (negative) to VDOCK_RTN.

Worked examples

Example 1 — a first encounter with Palm Multi-Connector

Start with the simplest possible case. Write down what Palm Multi-Connector claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Palm Multi-Connector before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Palm Multi-Connector ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Palm Multi-Connector

In research: Palm Multi-Connector appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Palm Multi-Connector in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Palm Multi-Connector is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer buses, Palm OS devices, so understanding it makes those chapters shorter.
In everyday life: Look for Palm Multi-Connector outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
