How it Works: Lithium-Ion Battery Explained (PDF)
Power to go—that’s the promise batteries deliver. They give us all the convenience of electricity in a handy, portable form. The only trouble is, most batteries run flat very quickly and, unless you use a specialized charger, you then have to throw them away. Learn how to extend battery life and how to avoid common mistakes with the lithium battery charging.
SIMULCHARGE™ Technology (PDF)
Simulcharge (s’aɪmʊltʃʌrdʒ) noun is a mode that allows portable devices such as tablets or phones , also called OTG devices, to operate as a USB Host controller while simultaneously being charged. 1 USB mode where tablet is placed into OTG/Host Mode but has its battery simultaneously charged. 2 Mode where tablet act as a USB Host and has its battery simultaneously charged. 3 USB mode for portable devices. Currently limited to Samsung Tablets.
USB Power Budgeting (PDF)
Devices powered on the USB bus face a very limited power budget, particularly in USB 2.0 and earlier. This white paper discusses how to assess the power needs of USB-powered systems, looks at power budgeting, discusses the impact of voltage drops on the power budget, and makes suggestions on supplementing power with the use of powered USB hubs.
Power over Ethernet (PoE) (PDF)
Devices powered over their Ethernet connection — using the same cable as that carrying data — are becoming increasingly commonplace. In many applications PoE saves the need for additional cabling and dedicated power sourcing. This white paper discusses the technology and its applications.
Serial Device Server Applications (PDF)
Serial device servers — LAVA Ether-Serial Links — are a well established and powerful means of making a serial port available over a LAN, WAN, or Internet. Beyond simply IP-enabling serial peripherals however, Ether-Serial Links can manage multiple ports, convert serial port configurations, and much more.
RS-232 Serial Ports (PDF)
Here’s a white paper with useful information on the most commonly-used serial interface, RS-232. It includes cabling and pinout information that will help you set up your port, and a full theoretical overview that will make you better understand the ins and outs of RS-232.
IEEE 1284 Parallel Ports (PDF)
IEEE 1284, better known as parallel, was the workhorse high-speed peripheral interface for many years. Although eventually overtaken by USB in many applications, parallel ports are still an important part of the computing world.
USB 3.0: SuperSpeed USB (PDF)
It’s here, it’s fast, and it’s so much more. USB 3.0 offers better power management and more intelligence all round, in addition to being ten times faster than USB 2.0. Now is a good time to learn what’s up with USB 3.0.
Choosing USB Hosts (PDF)
Covers USB 1.1 and USB 2.0 host adapters, with general considerations that also apply to USB 3.0.
