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.

NOTES:

N/A – not applicable

VIO – I/O logic level. VIO is 2.8V by default; can be conﬁgured to 3.3V by

changing 0 ohm jumpers on the board.

1. SUPPLY pins are internally connected.

2. Disable input for WiFi supply (independent of GPS supply). Pin is

internally pulled up to SUPPLY voltage and can be left ﬂoating for always-

on operation. For shutdown, pull low with open collector/drain driver.

3. The GS1500M UART interfaces are cross connected to appear as a

DCE devices on the WiFi1500CF pinout.

4. N/C (no connection). The pin has no function and makes no electrical

connection.

5. Must be enabled by installing 0 ohm jumpers on the board. See

Conﬁguration Options section.

6. Not supported in standard ﬁrmware

7. Enable input for loading GS1500 ﬁrmware. Pin is internally pulled up

to VIO voltage and can be left ﬂoating. For enabling ﬁrmware load,

pull low with open collector/drain driver. (There is also provision for a

jumper for this on the board.).

8. Connected to GS1500 RESET pin and a 22K pullup resistor to 3.3 V

through a 1 k series resistor.

9. Only available on WiFi1500CF V1.0 boards (with GPS). Pin is N/C

(no connection) on WIFi1500CF V2.0 boards.

2.4 Power Connections

SUPPLY – 5.0 volt supply for the module (referenced to the GROUND pins). The two SUPPLY pins (pins 1 and 2) are

internally connected together.

PWRMON / VAUX – These pins are connected to the internal VIO supply that powers the level shifters used on

several of the I/O pins. The two pins are internally connected; the different names are used to maintain compatibility

with other CF Plug-In products. This voltage can be used as a reference for an external interface. The VIO supply

can be connected to an internal 2.8 volt supply or an internal 3.3 volt supply. The default is the 2.8 volt supply so

as to be compatible with the CF Plug-In host products (e.g T2, 400AP). See the Conﬁguration Options section for

information on changing the VIO supply.

The following I/O pins use the level shifters or are associated with the VIO supplies:

14 UART1_RX 41 SPI_MOSI

15 GPIO301 42 SPI_CS

16 GPIO31 43 SPI_CLK

17 SERVICE2

1. These pins are not connected on the WiFi1500CF v2.0 (w/o GPS)

2. This pin uses a discrete transistor implementation for a level shifter.

ENABLE – Used to disable the GS1500M and level shifter power supplies. This pin is internally pulled up to the

SUPPLY voltage which enables the power supplies by default. Pulling this pin low will disable the internal GS1500M

and level shifter power supplies. The GPS supply is unaffected. This can allow for reduced power consumption by

disabling the GS1500M WiFi module while allowing the GPS receiver to continue to operate.

2.5 Screw Mounting

The WiFi1500CF allows for the use of a #4 machine screw to help keep a socketed module in place where

environmental variables may cause problems otherwise. If the user wishes to have a stand-off underneath the

module to help alleviate possible stress from mounting hardware, below are the Janus part numbers and associated

drawings for an available solution.

1 Jumpers must be installed to connect these pins. See the Conﬁguration Option section.

2 The GS1500M VOUT_1V8 pin can be jumpered to the JN3 module’s BOOT pin. See the Conﬁguration Option section.

Antenna

The GS1500M has an on-board PCB (printed circuit board) antenna and a u.FL RF connector to support an external WiFi

antenna. The u.FL connector is located on the edge of the GS1500M module board that overhangs the WiFi1500CF board.

Commands entered via the GS1500’s UART or SPI port can be used to select which antenna is used.

UART interface

UART0 on the GS1500M is brought out through a level shifter and support is provided for TX, RX, CTS and RTS signals. While

the GS1500 has DTE (Data Terminal Equipment) UART conﬁguration, an internal crossover network converts this to appear

as a DCE (Data Communications Equipment) device on the pin-out of the WiFi1500CF. This makes it compatible with host

processors (e.g. Janus 400AP, T2) and other microcontroller devices that typically present a DTE UART interface. The default

settings for the UART0 interface are 9600 baud, 8 bit characters with no parity bits and one stop bit (8N1).

ASYNC

Connected to the GS1500M GPIO19 pin through a level shifter. When enabled via the command interface, this pin can be

used to provide notiﬁcation of asynchronous messages at the UART0 port. (See ‘Enhanced Asynchronous Notiﬁcation’ in the

GS1500M Serial-to-WiFi Adapter Application Programming Guide.)

SPI interface

The GS1500M SPI slave port is brought out through a level shifter and support is provided for the SPI_MISO, SPI_MOSI, SPI_CS,

SPI_CLK and the SPI_WAKE pins. The SPI port provided as an alternative to the UART0 interface on the GS1500M, and can

provide faster communication speeds (up to 3 Mbps) than the UART0 interface.

SPI_WAKE

Connected to the GS1500M GPIO28 pin through a level shifter. This pin is asserted high during data transmission periods.

It notiﬁes the host (SPI master) that it can begin receiving data by providing the SPI clock signal. In addition, it provides an

indication that the SPI interface is operational following start up. (See ‘SPI Interface Handling‘ and ‘Node Start Up Handling’ in

the GS1500M Serial-to-WiFi Adapter Application Programming Guide.)

3. WiFi Module Continued

3.2 WiFi Module Operations

Operation of the GS1500M WiFi module requires a serial connection to the device, either through its UART0 port

or its slave SPI port. (The SPI Mode 0 ﬁrmware load is required to support the SPI port connection.) Operational

commands and data strings are transferred using the serial connection. A complete description is beyond the scope

of this User Manual; please refer to the GS1500M Serial-to-WiFi Adapter Application Programming Guide.

The GS1500M can operate in 3 different modes that are related to how the serial interface is utilized:

Command mode (default) – Command strings using an ‘AT’ command format can be used to conﬁgure the module.

Data processing mode – Using escape character sequences, data can be sent and received from up to 16

different IP address-port locations.

Auto connect mode – The module can be pre-conﬁgured to connect to a network at start-up as either a TCP

or UDP client or server. Following start-up, serial data is automatically sent to and received from a remote IP

address via the selected protocol.

3.2.1 Set-up:

This section describes the minimum hardware set-up requirements and some basic command procedures to

operate the GS1500M module.

3.2.1.1 Hardware Set-up

Hardware set-up requires the following:

- UART connection (GS1500M UART0). At a minimum the TX and RX lines must be supported. The WiFi1500CF

interface pins are at VIO voltage levels; the default value is 2.8 volts. The default UART conﬁguration is 9600 baud, 8

bits, no parity, 1 stop bit (8N1).

- Antenna selection. The GS1500M has a printed circuit antenna that is selected by default. Alternatively, an external

WiFi antenna may be connected to the u.FL connector on the GS1500M module board. In this case the U.FL

connector antenna must be selected via a AT command; see the Basic Conﬁguration section below.

- Power. Apply power to the unit by providing 5.0 +/- 0.25 volts across the WiFi1500CF SUPPLY and GND pins.

3.2.1.2 Basic Commands:

In general, the AT commands are insensitive to character case. Successful commands usually return the characters “OK”

(if the default verbose mode is enabled). Please refer to the GS1500M Serial-to-WiFi Adapter Application Programming

Guide for details. Those commands requiring user parameters are indicated with the parameter being given in inequality

brackets, e.g. <PARAMETER>. Below are a few basic commands that can be used to demonstrate serial connectivity

with the GS1500M:

AT+NSTAT=?  NetworkStatusquery

AT+WS   ScanforWiFinetworks

WT+NMAC=?  MACaddressquery

The following disassociate command should be used before proceeding with any of the operational examples given in the

sections below to insure that any previous operating mode is cleared:

AT+WD   Disassociate

A reset to factory default conditions can be achieved with the following command:

AT&F   Restoretofactorydefaults

3.2.1.3 Basic Conﬁguration:

When ﬁrst powered, the GS1500M module will initialize and then send “Serial2WiFi APP” to the UART port, whereupon

the module is ready to receive commands. (If the module has been conﬁgures to auto connect, a network status message

is sent instead.)

The antenna output should be set to the printed circuit board antenna or the external antenna connected to the u.FL

connector. The antenna selection command is:

AT+ANTENNA=<n>

Where <n> speciﬁes whether the printed circuit board antenna or the external u.FL antenna is selected:

1 = printed circuit board antenna

2 = u.FL connector

3. WiFi Module Continued

3.2 WiFi Module Operations continued

3.2.2 Operation examples

Below are several examples of conﬁguring the GS1500M module. The UDP Client example conﬁgures the

module to connect to an existing infrastructure WiFi network using command mode, then sends UDP data to

a server using data mode. The Web Provisioning example is a command mode sequence of instructions that

initiates the module’s provisioning web server. The Auto Connect example conﬁgures the unit to automatically

connect as a TCP server to a speciﬁc client. Upon restart in the Auto Connect mode a connection is made

between the client and server, at which point data can be transparently passed back and forth between them.

These examples assume that the GS1500M WiFi module begins conﬁgured in its default state, and that no

encryption is used.

3.2.2.1 UDP Client

Issuing the following sequence of commands will set up the GS1500M module as a station in an existing infrastructure WiFi

network:

AT+WM=0 Mode(0=infrastructure).

AT+NDHCP=1 DHCP(1=enable).

AT+WA=<SSID> AssociatewithaWiFinetworkhaving

 designatedSSID.

AT+NCUDP=<Dest-Address>,<Port> SetupUDPClient.SuccessfulCommandwillreturn

Returns:CONNECT<CID> aConnectionIdentiernumber.

At this point UDP data can be sent to a server (at <Dest-address>, <port>) with the following command:

<Esc>S<CID><data><Esc>E   SendUDPdata.

3.2.2.2 Web Provisioning

The web provisioning feature included in the default ﬁrmware load allows the GS1500M to host a few simple web pages

that allow for provisioning of the module. It can be set by issuing the following commands:

AT+NSET=<IP>,<SUBNETMASK>,<GATEWAYIP> StaticConguration.

AT+WM=2     Mode(2=limitedAccessPoint).

AT+WA=<SSID>,,<CHANNEL>   StartAPnetworkusingSSIDondesignatedCHANNEL.

AT+DHCPSRVR=1    DHCPserver(1=enable).

AT+WEBPROV=<USERNAME>,<PASSWORD> Startwebprovisioning.TheUSERNAMEandPASSWORD

      willberequiredtologin.

At this point a client can connect to the GS1500M module at it’s <IP> address. The GS1500M will request the

<USERNAME> and <PASSWORD> to be entered. This gives access to web pages hosted on the module that allow for

provisioning of the GS1500M.

3.2.2.3 Auto Connect

In the example below, the GS1500M module is conﬁgured to connect to an access point, the auto connect feature is

enabled, and the settings are stored in a proﬁle. When re-started, the unit will connect to the access point whereupon

serial data can be transferred to and from a remote IP address.

AT+NDHCP=1     DHCPenable

AT+WAUTO=0,<SSID>    Setautowirelessparameters(0=infrastructure).

AT&Y0     Settoloadprole0atstart-up

At this point the GS1500M module should be restarted, either by pulling the RESET pin (WiFi1500CF pin 47)

low or by removing and re-establishing power to the unit. The GS1500M will respond with its network settings

upon successfully associating with the wireless network. Serial data can now be sent to and from the GS1500

via the serial port. A telnet session or a simple TCP terminal can be opened at the client (destination IP) to

demonstrate the sending and receiving of serial data.

In order to terminate the Auto Connect session, enter a sequence of three ‘+’ (plus) symbols followed by one

second of no data being entered. Following this the command mode will be available.

3.3 WiFi Module Firmware

The GS1500M WiFi module can be loaded with several versions of the S2W (Serial-to-WiFi) application ﬁrmware.

Because of limited memory, certain features are only exclusively available in speciﬁc ﬁrmware loads. By default,

the module is loaded with the Web Provisioning ﬁrmware. The table below illustrates the features available on the

available ﬁrmware loads:

4. GPS Module (Optional)

The Telit JN3 GPS receiver provides position and timing information using standard NMEA (National Marine

Electronics Association) strings over a UART interface. In addition, a 1PPS signal is available to provide an accurate

timing mark when a high quality ﬁx is available. A complete description of this module is beyond the scope of this

document. Detailed hardware and operational information can be found in the JN3 GPS receiver documentation

listed in the Applicable Documents section.

Antenna

A u.FL connector is provided for connecting a GPS antenna. This connector is located on the top surface of the

WiFi1500CF board at the pin 25 corner. This connector also provides a 3.3 volt bias at the antenna connector for

powering remote ampliﬁers that are often built in to GPS antennas.

Do not short the antenna output

UART interface

The UART on the JN3 GPS module is brought out through a level shifter and support is provided for the TX and

RX signals. The default setting for the JN3 GPS UART interface is 4800 baud, 8 bit characters with no parity bits

and one stop bit (8N1).

The JN3 GPS module provides a NMEA interface on the UART; more information can be found in the ‘JN3

Product Description’ document listed in the Applicable Documents section.

1PPS output

A 1PPS (one pulse-per-second) output is available from the GPS receiver when a high quality (3D) position ﬁx is

obtained. The pulse width is 200 ms and the leading edge of the pulse is synchronous with one second timing.

The 1PPS signal appears on the WiFi1500CF pin that is designated as the GS1500M UART0 DCD pin. The DCD

pin is a standard 1PPS interface on serial connections to hosts running NTP (network timing protocol) applications.

For a full implementation, the JN3 UART TX and RX signals should also appear on the UART0 interface. This can be

accomplished by changes to the conﬁguration jumpers. See the Conﬁguration Options section.

4.2 WiFi Module Operation

Hardware set-up requires the following:

- UART connection (JN3 UART). The TX and RX lines are supported on the WIFi1500CF pins 34 (GPS_TX) and 35

(GPS_RX). These interface pins are at VIO voltage levels; the default VIO value is 2.8 volts. The default UART

conﬁguration is 9600 baud, 8 bits, no parity, 1 stop bit (8N1).

- Antenna connection. The JN3 requires that a suitable external GPS antenna be connected to the u.FL connector

on the WiFi1500CF board. The GPS antenna has to be located so as to allows a reasonable ‘view of the sky’ in

order to receive the GPS satellite signals.

- Power. Apply power to the unit by providing 5.0 +/- 0.25 volts across the WiFi1500CF SUPPLY and GND pins.

Basic operation of the JN3 GPS module consists of utilizing the NMEA messages that are output by the module on

the UART interface. By default, the module will output the following NMEA messages on start-up:

Message Rate

GGA once per second

GSA once per second

RMC once per second

GSV once every ﬁve seconds

NMEA input messages can be used to control a number of the JN3 GPS modules operational characteristics,

including the UART interface parameters, the standard NMEA messages being output, and the rate at which the

NMEA messages are output. See the SiRF NMEA Reference Manual for additional information. Below is a complete

list of the available NMEA messages:

Message Description

GGA GPS Fixed Data

GLL Geographic Position – Latitude/Longitude

GSA GNSS DOP and Active Satellites

GSV GNSS Satellites in View

RMC Recommended Minimum Data

VTG Course Over Ground and Ground Speed

ZDA 1PPS Timing Message

In addition to the NMEA messages, the JN3 module supports the SiRF One Socket Protocol (OSP) protocol. Please

refer to the Applicable Documents section for further reference material.
