BB2400 Installation
And
Operation
Overview
The BB2400 system consists of a single ISA format PC card and an external antenna/transceiver
unit used in a x86 based personal computer and configured as a wireless router. The PC is
configured with a version of the Linux operating system combined with a special driver to
exercise this system. This configuration lends itself to two discrete steps. The first is hardware
installation in the PC. The second, is the physical installation of the system.

Due to the unique nature of the product, installation should be limited to qualified individuals,
understanding the local building and safety codes.

PC Hardware Installation
The ISA portion of the system is designed to be installed into a standard PC system. As
mentioned, the LINUX operating system is the “heart” of the router, assisted by a custom driver
unique to the BB24000 card. Since Linux is an “open source” architecture, to simplify
installation and ensure correct hardware-software compatibility, the software is available at
installation only in a compiled, ready to run, image. All unnecessary code is eliminated and a
very compact and efficient operating system is the result. This router operating system software
is distributed on 3.5” floppy disk, and is a completely bootable image at this point. The PC can
function by booting directly from the floppy with no additional mass storage. If a hard drive is
present, booting from the hard drive can be accomplished by copying this floppy image to the
hard drive. Depending on master or slave configuration, a different floppy is used. This
simplifies the installation and reduces the chance of installation error.

Every unit has a unique MAC address, just as with a conventional network card. When a master
is set up, and prior to operation, the MAC address of the slave unit must be entered into a table at
startup. This allows the master to send out a request to its associated slave. In this way, its
associated master can only address slaves. Likewise, a slave could possibly decode data from
another master, but will throw away any data not destined for its unique MAC address. This
method of operation is very similar to a wire based LAN.

Once the system is setup, it is attached to a LAN just as any other router. Since network
topologies are widely varied, this installation is left to a network professional, and is outside the
scope of the basic hardware installation. Operation requires no user intervention, once
programmed with the proper addresses and netmasks. Upon application of power, the unit loads
the program code, and becomes a wireless router.

Antenna Hardware Installation
The BB2400 Transceiver/ Antenna is designed to be mounted so that it has direct “line-of-site” to
its companion. Since most installations must comply with local building codes and safety
