1.4 FCC Advisory Statement

This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly (that is, in strict accordance with the manufacturer's instructions), may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the owner will be required to correct the interference at his own expense.

If this equipment does cause interference, which can be determined by turning the unit on and off, the user is encouraged to try the following measures to correct the interference:

  • Reorient the receiving antenna.
  • Relocate the unit with respect to the receiver.
  • Plug the unit into a different outlet so that the unit and receiver are on different branch circuits.
  • Ensure that mounting screws and connector attachment screws are tightly secured.
  • Ensure that good quality, shielded, and grounded cables are used for all data communications.
  • If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions.

The following booklets prepared by the Federal Communications Commission (FCC) may also prove helpful:

  • How to Identify and Resolve Radio-TV Interference Problems (Stock No. 004-000-000345-4)
  • Interface Handbook (Stock No. 004-000-004505-7)

1.6 Conventions Used

Filenames and code statements are presented in Courier.

   Similarly, code blocks or sections better suited for
   plain text display, such as example terminal output, 
   are presented in indented preformatted text.

Commands issued by the reader are indicated in bold Courier. New terms or important concepts are presented in italics.

When you see a pathname preceded with three dots, this references a well-known but unspecified top-level directory. The top-level directory is context dependent but almost universally refers to a top-level Linux source directory. For example, .../arch/arm/kernel/setup.c refers to the setup.c file located in the architecture branch of a Linux source tree. The actual path might be something like ~/sandbox/linux.2.6.21/arch/arm/kernel/setup.c.

Hardware interfaces, such as pin numbers or names, are described by ALL CAPS.


Text appearing in this manner offers notes and/or comments that will aid in your understanding.


Text appearing in this manner offers a warning. You can make a mistake here that hurts your system or is hard to recover from.

1.7 TS-WIFIBOX-2 Application Kit

The TS-WIFIBOX-2 is an Application Kit assembled by Technologic Systems, Inc. The TS-WIFIBOX-2 is made up of three major components: 1) the TS-7553 as the base single board computer or main controller board, 2) a USB WiFi Adapter (currently WIFI-G-USB-2), and 3) an enclosure. The TS-7553 is screwed into the bottom of the enclosure, the USB WiFi Adapter is plugged into the top internal USB port, and the rest of the enclosure including the end cap and top are assembled, enclosing the TS-7553 and USB WiFi Adapter. For images, click on the thumbnail on the main product page or simply click here.

The TS-WIFIBOX-2 already includes all the necessary Linux drivers and packages in order to enable out-of-the-box WiFi application productivity. It is designed to provide extreme performance for applications which demand high reliability, fast bootup/startup, and WiFi connectivity at low cost and low power (about 3.2 watts), such as a gateway or firewall, protocol converter, Ethernet to WiFi bridge, web server, WiFi audio, or unattended remote applications. The TS-WIFIBOX-2 supports connections to unencrypted networks, WEP, WPA, WPA2 encrypted networks, and can also operate in Ad-Hoc mode for multi-node connections.

1.8 KIT-WIFIBOX-2 Development Kit

The KIT-WIFIBOX-2 Development Kit for the TS-WIFIBOX-2 series includes all equipment necessary to boot into the operating system of choice and start working. The development kit is highly recommended for a quick start on application development. The KIT-WIFIBOX-2 Development Kit for the TS-WIFIBOX-2 includes:

  • Development 2GB microSD with ECLIPSE IDE and USB microSD card reader (MSD-2GB-USB-7500)
    • Debian Linux 5.0 (Lenny) Distribution compiled for ARM
    • Full tool-chains (uclibc and glibc) for cross compiling for ARM
    • Utility source code (ie. sdctl.c) and example programs
  • TS-9448 Console Board to 1) bring out TTL level console UART to RS-232 levels and 2) provide a recovery mechanism.
  • Regulated DC power supply and all cables including NULL Modem cable, etc.


TS-WIFIBOX-2 is not included in the KIT-WIFIBOX-2 Development Kit (sold separately).

1.9 Benefits

Out-of-the-Box Productivity

Technologic Systems Linux products get you to your application quickly. Our Single Board Computers boot directly to Linux as shipped. There is no complicated CMOS setup or configuring of a Linux derivative Operating System to source, define, and load. A Technologic Systems SBC user can power up the board and immediately begin application development.

Of course, should you wish to configure your own version of Linux or use a different operating system, this is easy too. Technologic Systems provides the solution to fast application development without tedious OS configuration.

Small Form Factor

The TS-WIFIBOX-2 is packaged in a clean, compact plastic enclosure which can fit comfortably within most spaces when compared to it's full sized PC counterpart. The TS-WIFIBOX-2 measures 139.88mm (5.507 in.) W x 102.02mm (4.016 in.) D x 35.06mm (1.380 in.) H.

A Plethora of External Connections

The TS-WIFIBOX-2 Application Kit offers many connections and buses via the 26-Pin header, such as GPIO, SPI, I2C, I2S, that give the TS-WIFIBOX-2 Application Kit the added benefit of being able to interact with external peripherals and sensors while being wirelessly connected to a network.

Talk with Engineers Directly
