4 The GS22X-XX Series Gateways
1.1 Overview
The LSI Wireless Gateway system consists
of one or more
LSI Wireless Gateway and
one or more
LSI GS series sensors. The LSI
Gateway is a generic receiver/transmitter that
transfers information received from the sensors
to an external user interface or control unit. The
LSI Gateway is compatible with LSI GS series
sensors. There are many variations and possible
congurations of the
LSI Gateway designed to
integrate with a wide variety of applications.
External communication with the
LSI Gateway
can be handled through a number of different
optional communication ports including RS232,
USB, CAN-bus, J1939, and voltage outputs. The
LSI Gateway allows information to be exchanged
in both directions between the
LSI wireless
network and the communication port.
The
LSI Gateway has two operating modes:
network controller and listen only. Understanding
the two operating modes is important to successful
set-up of the wireless network.
Network Controller Mode
The
LSI Gateway controls a wireless network
of up to 32 sensors. The
LSI Gateway wakes
and initiates communication with all sensors in
its network on start-up. On shut-down the
LSI
Gateway instructs all sensors in its network to
enter low power sleep mode.
Listen Only
The
LSI Gateway listens to all LSI GS series
sensors within range but does not actually
communicate with them. The
LSI Gateway has
no direct effect on the network it is listening to.
System sensors need a network controller to avoid
entering low power sleep mode. The network
controller can be any compatible display or
LSI
Gateway.

WARNING! The system is designed to aid
in the collection of information and is in no
way a substitute for safe operating practice.
