NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE
SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY
SITUATIONS. No OEM Linx Remote Control or Function Module
should be modified for Life and Property Safety Situations. Such
modification cannot provide sufficient safety and will void the product’s
regulatory certification and warranty.
Customers may use our (non-Function) Modules, Antenna and
Connectors as part of other systems in Life Safety Situations, but
only with necessary and industry appropriate redundancies and
in compliance with applicable safety standards, including without
limitation, ANSI and NFPA standards. It is solely the responsibility
of any Linx customer who uses one or more of these products to
incorporate appropriate redundancies and safety standards for the Life
and Property Safety Situation application.
Do not use this or any Linx product to trigger an action directly
from the data line or RSSI lines without a protocol or encoder/
decoder to validate the data. Without validation, any signal from
another unrelated transmitter in the environment received by the
module could inadvertently trigger the action.
All RF products are susceptible to RF interference that can prevent
communication. RF products without frequency agility or hopping
implemented are more subject to interference. This module does not
have a frequency hopping protocol built in.
Do not use any Linx product over the limits in this data guide.
Excessive voltage or extended operation at the maximum voltage could
cause product failure. Exceeding the reflow temperature profile could
cause product failure which is not immediately evident.
Do not make any physical or electrical modifications to any Linx
product. This will void the warranty and regulatory and UL certifications
and may cause product failure which is not immediately evident.

Introduction
The Linx GPS and GNSS modules offer a simple, efficient and
cost-effective method of adding GPS or GNSS capabilities to any product.
The Master Development System is intended to give a designer all the tools
necessary to correctly incorporate the modules into an end product. The
development boards themselves serve several important functions:
•ꢀ Rapid Module Evaluation: The boards allow the performance of the
modules to be evaluated quickly in a user’s environment.
•ꢀ Application Development: An onboard prototyping area allows for the
development of custom circuits directly on the development board. All
signal lines are available on a header for easy access.
•ꢀ Design Benchmark: The boards provide a known benchmark against
which the performance of a custom design may be judged.
The Master Development System includes one assembled development
board, one receiver module on an evaluation board, one spare receiver
module for use on your first prototype, one SH Series active GPS antenna,
4 AAA batteries and full documentation.

Initial Setup
The Prototyping Area
Unpack the development system and install the AAA and coin-cell
batteries. Connect the external GPS antenna. The power switch selects
between the battery pack or USB power if the board is plugged into a
USB bus. To use the display, turn the OLED display power switch on. The
development board is now ready for use. After turning on the power, the
module determines its current position. Please note, the time required for
an initial fix or after long periods of storage is considerably greater than in
subsequent operation. Please refer to the module’s data guide for complete
information regarding Time-To-First-Fix (TTFF). To protect the display and
extend its life, turn off the display before turning off the board.
In addition to its evaluation functions, the board may also be used for
actual product development. It features a prototyping area to facilitate the
addition of application-specific circuitry. The prototyping area contains a
large area of plated through-holes so that external circuitry can be placed
on the board. The holes are set at 0.100” on center with a 0.040” diameter,
making it easy to add most industry-standard SIP and DIP packages.
External circuitry can be easily interfaced with the receiver through the
breakout header (J3) on the upper right of the prototyping area. A switch
controls the routing of data into the receiver module. By default the switch
is set for operation with the on-board USB module. When communicating
with the module from the prototyping area this switch should be set
to Prototype Control. At the bottom of the prototyping area is a row
connected to ground and at the top is a row connected to the 3.3V power
supply.
Troubleshooting
If the boards fail to work out of the box, then try the following:
•ꢀ Check the batteries to make sure they are not dead
•ꢀ Check to make sure that the power switch is in the correct position
•ꢀ Check that the antenna is installed correctly
Note: The on-board 3.3-volt regulator has approximately 300mA of
headroom available for additional circuitry. If added circuitry requires a
higher current, the user must add an additional regulator to the prototype
area or power the board from an external supply.
•ꢀ Check that the data routing switch is set appropriately
If all of these appear to be in order, please call +1 800 736 6677 or e-mail
techsupport@linxtechnologies.com for technical support.

The Receiver Section
The USB Section
The development board features a Linx QS Series USB module for
interface to a PC. This allows the board to be used with the supplied
development software or with custom software developed by the user.
The receiver module is mounted on an evaluation board which plugs into
headers on the main development board. The evaluation board has an
SMA antenna connector to allow the attachment of many different styles of
GPS antennas, including the included SH Series active GPS antenna. Each
receiver module has its own evaluation board, but all of them are designed
to fit into the same socket on the main board.
Figure 6: The Development Board USB Section
Drivers for the USB module are included on the software CD in the kit
or may be downloaded from www.linxtechnologies.com. Additional
information on using the QS Series USB module can also be found on the
website.
Figure 5: The Development Board Receiver Section
On the bottom of the main board is a CR2032 coin cell battery that
provides power to the Real Time Clock (RTC) and SRAM when the receiver
is powered down. This allows the receiver to start up and obtain a position
fix faster. This cell provides about two years of operation.
The USB connection also allows the board to be powered by the USB
bus instead of batteries. This can be convenient during development to
eliminate the need for frequent battery replacement.

The Display Section
Master Development Software
The Master Development System features an OLED screen that displays
the navigation information from the receiver module. This allows the
development board to act as a stand-alone evaluation system without the
need for any additional software.
The development system is supplied with Windows-based software that
communicates with the development board through the USB module. This
software displays the information from the receiver module in the different
NMEA formats and the satellite information, signal strength, and positions
are displayed graphically. If the PC is connected to the internet, the
software plots the current location on Google Maps. Full details are in the
software’s User’s Guide.
Figure 7: The Development Board Display Section
The display is driven by an on-board microcontroller located under
the display. Data from the receiver module is connected directly to this
microcontroller. The microcontroller receives data at the receiver’s default
9,600bps.
Note: If the receiver’s baud rate is changed, it will not be able to
communicate with the microcontroller.
The display and microcontroller pull about 100mA when fully powered, so
a power switch is supplied to deactivate the display area when not in use,
saving battery life. To protect the display and extend its life, be sure to turn
the display section off before turning off the main power to the board.
