SXL1
The SXL1 is a small but fully self-contained, global satellite-based tracking device capable of
determining location using GPS and reporting the location over a low earth orbit (LEO) satellite
network. The SXL1 is powered by a field replaceable battery and requires no wiring or harnesses for
use.
The SXL1 communicates data via the Globalstar Simplex Data Service. This satellite service utilizes
low power, one-way transmitters to relay data from locations globally to a back office server
accessible over the internet through secure connection. The use of one-way, simplex satellite
communications is a proven, reliable method to inexpensively collect widely scattered asset data.
The device is speak only, so there is no way to communicate to the device in the field. This feature is
mitigated by a rich configuration capability that enables the SXL1 to automatically detect situations
where a data update is desired, such as start and stop or while in motion.
This Users Manual describes how the SXL1 is configured and the protocol for on-air data payload
and internet XML packets. This document provides a generalized overview only. Consult Numerex
for more details and options of relaying data.
Connecting the SXL1 to the
Computer
The SXL1 is available in preconfigured
operational modes. These modes are
determined at point of manufacture or at OEM
depot distribution. Field configuration should
only be performed by installation specialists
to avoid configuration errors. Since the
device does not support over-the-air
configuration and must be connect using a
short range RF link, it is important the devices
are properly configured for use.
The SXL1 contains a short range RF
transceiver for setting the device for
operation. This transceiver communicates with a like transceiver in the SXL1 programming device.
The SXL1 programmer provides the interface for configuring the device using the SXL1_Programmer
setup tool available from Numerex.
The SXL1_Programmer software tool is designed to operate on a Microsoft Windows
®
XP -based
computer. The Microsoft .NET framework is also required to run the configuration setup software.
This is a default Windows
®
XP add-on, and may also be downloaded from www.microsoft.com
without charge.
A USB Type A cable coming from the SXL1 programmer (right) is used to connect to the computer
being used to configure the device. Connect the computer to the SXL1 programmer using the USB
cable, and then run the SXL1_Programmer software tool. The SXL1_Programmer software will
automatically begin searching for available SXL1 units.
SXL1_Programmer Software
The SXL1_Programmer is a Windows
®
executable software program designed to access and
configure the SXL1. The program can simply be copied to a directory on the computer.
