The Tablet Mini-Office

23rd Thursday, 2014  |  Life at LAVA  |  no comments

The LAVA SimulChage USB, in conjunction with one of the supported Samsung tablets, can make the backbone of a highly functional mini-office system.

Peripherals such as keyboards, mice, touch pads, printers, memory sticks, external hard drives, and Ethernet adapters can all be components. As far as printers go, there are basically two routes: using the Samsung software that comes installed in the tablets (“Samsung Mobile Print App”) and that is compatible with certain Samsung printers, or using a third-party application (such as PrinterShareâ„¢ Mobile Print (https://play.google.com/store/apps/details?id=com.dynamixsoftware.printershare&hl=en)) to print to assorted makes and models of printers. You will need to verify compatibility in your particular case.

Here are a some sample setups:

Setup 1: Wired keyboard, mouse, external hard drive, and printer

This first setup is a fully wired office. The power requirements for such a system involve wall power for the printer, and for two USB power domains.

Setup 2: Wired keyboard, mouse, external hard drive, and wireless printer

This second setup is a hybrid design that uses the wireless printing supported natively in the tablet by the Samsung Mobile Print App. The software is supplied with the Samsung tablets, but the printer needs to be one of the Samsung-supported printer models.

Setup 3: Wired USB memory stick, and wireless keyboard/touch pad and wireless printer

This third setup has simplicity as its characteristic, as it uses no USB hub (powered or otherwise).

Setup 4: Wired Ethernet, network attached storage, networked printer, and locally connected keyboard and mouse

Many more combinations are possible. Using a wired Ethernet connection, for example, is easy and described in a blog post and video.

In general, the things to bear in mind are that the system needs to be designed with 1) supported components, 2) correct printer support, and 3) care to observe the USB OTG power budget. Discussion of USB power budgeting can be found in this LAVA white paper.
