You must obtain the following hardware to create your OpenAP.

An access point based on the Eumitcom WL11000SA-N board.

This is the OpenAP hardware platform. Eumitcom WL11000SA-N boards are resold as:

  • US Robotics (USR 2450) (tested)
  • SMC EZconnect (2652W) (tested)
  • Addtron (AWS-100) (untested)

There may be others based on the Eumitcom board. This particular platform has the following specifications:

  • Ethernet Controller -- NE2000
  • Processor -- AMD ELAN SC400
  • Flash -- 1 Megabyte
  • RAM -- 4 Megabytes

A linearly mapped memory card

This card is used to program the flash chip on the WL11000 board. We use a MagicRAM Industrial SRAM Memory card.

The linearly mapped memory card must be 2 megabytes large and readable at 3.3V. You may use a larger memory card, but the OpenAP build process only supports a 2 megabyte image for the card flash by default.

From our experience, SRAM memory cards are better supported under linux than Flash memory cards.

A null modem cable.

The null modem cable is used to attach the RS-232 serial interface on the back of the access point, to a computer. On the computer, you may run a terminal program to access the unix bash shell on the access point.

A software terminal program

A terminal program such as linux Minicom or windows HyperTerminal is used to access the unix bash shell on the access point, via the null modem cable.
