1. Scope:
This document provides a detailed hardware interface description and some general operating instructions for the
WiFi1500CF. It does not cover the detailed operating instructions of the individual WiFi (GS1500M) or GPS (JN3)
modules. Please refer to the documentation listed in the Applicable Documents section for further information
concerning operation of these modules.
2. WiFi1500CF Overview
The WiFi1500CF provides Wi-Fi connectivity and an optional GPS receiver in a footprint compatible with the Janus
line of CF Plug-In products. A GainSpan GS1500M module provides WiFi 802.11 b/g/n radio features and comes
with S2W (Serial-to-Wi-Fi) application firmware. The GS1500M is easily configured via an AT type command set
over a UART interface, and support for a SPI interface is available through an optional firmware load. A Telit JN3
GPS receiver is available as an option and provides a standard NMEA UART interface and 1PPS output for tracking
solutions and precision timing requirements.
The power supply and I/O signals are compatible with Janus CF Plug-In host products such as the Terminus T2
and 400AP, or the WiFi1500CF can be used in a custom based solution. The WiFi1500 was specifically designed
to provide customers with a cost effective product that is easily integrated into new and existing designs. It is
completely interchangeable with other CF Plug-In products to allow for maximum network flexibility while removing
the worry of product obsolescence.
