802.11b/g Wireless LAN – TCP/IP (BISM II Pin Compatible)
Part Number: WISMC01BI
1. General Description
EZURiO’s Wireless LAN Module is a fully integrated and qualified solution unlike other modules all the
drivers and antenna are integrated. This makes certain the module is designed for lowest cost of
integration and ownership for designers wishing to incorporate Wireless LAN functionality into their
products.
The Wireless LAN module is one of the most compact complete Wireless LAN solutions, incorporating
all the required 802.11b/g drivers and an Ultra Compact TCP/IP and the EZURiO UWScript language
embedded directly into the module, making it ideal to integrate into Machine 2 Machine applications.
The EZURiO Wireless LAN module contains all of the hardware, firmware and embedded drivers for a
complete Wireless LAN solution, requiring no further components. The Module has an integrated, high
performance antenna which is matched with the Wireless LAN RF and baseband circuitry. The
firmware integrated into the module interfaces with the host via a UART which carries control and
data frames. The TCP/IP stack requires minimal operating overheads from the operating system and
allows simple passing of control frames contain simple commands used to configure and monitor the
module operation into EZURiO’s command interpreter.
The feature rich command set abstracts the Wireless LAN protocol from the host application, saving
many months of programming and integration time. A low cost development system is available for
fast product evaluation and development.
In addition to the Wireless LAN functionality, the module provides access to 9 General I/O lines and 2
analogue input lines. These can be configured using scripts to provide control or monitoring of simple
devices such as switches or LEDs without requiring any external processing. Both the GPIO and ADC
lines can be accessed using scripts over either via the wired host UART connection, or remotely over
the Wireless LAN connection.
The Wireless LAN module is supplied in a small pcb form factors (22.0mm x 34.0mm x 7.6mm), that
connects to a main pcb using a 40 way Hirose connector which is pin compatible with the EZURiO
Bluetooth Intelligent Serial Module BISMII. The module includes a high sensitivity, high gain antenna
which provides excellent range. Typical open field performance provides ranges of over 100 metres.
Support is provided for low power modes that make the Wireless LAN module particularly applicable
to battery powered installations. The Wireless LAN module is Lead-free and is RoHS compliant and
supports an industrial temperature range of -40°C to +85°C.
