Using the Lantronix SGX 5150 Serial Device Server
Application Note #28 - Revision 01/2021
Overview
The Lantronix
industrial wireless device serial servers and Ethernet Bridge/Routers are built for networking
equipment in an array of machine-to-machine (M2M) applications. The SGX 5150 features an industrial
strength enclosure and operates over
a wide temperature range (-40° to 70°C) to withstand challenging M2M
environments. Dual port design allows connection of up to 2 devices. Dual-band Wi-Fi supports both 2.4GHz
and 5GHz networking.
Security features include wireless security; network security; and device security (multi-level encryption
capability to protect configuration data).
This Application Note details the configuration steps necessary to use the Lantronix SGX 5150 Device Server
with several Campbell Scientific
®
data loggers including the CR2XX, CR3XX, CR800, CR1000 and CR6 and
the Canary Systems
MLGPS
module.
Definitions
Ad-Hoc Network
: An ad-hoc network is one of the two types of wireless networks (the other is "Infrastructure")
and is not very common. Ad-hoc networks do not require a wireless network access point and are considered
"de-centralized". Ad-hoc networks are convenient to allow devices and/or PC's to communicate with each other
in the absence of a centralized network.
DHCP
: Dynamic Host Configuration Protocol (DHCP) is a mechanism used in computer networks to assign IP
addresses automatically.
Infrastructure Network
: An infrastructure network is one of the two types of wireless networks (the other is
"Ad-Hoc") and is the most common. Infrastructure networks require a wireless network access point to manage
and forward traffic to and from the wireless network.
SSID
: Service Set Identifier (SSID) is the unique identifier for a wireless network, either infrastructure or ad-
hoc. The SSID is used to configure each device or PC to select the wireless network that you want it to
communicate on.
Wireless Network Access Point (AP)
: A wireless network access point is a Wi-Fi router that is used to setup
a wireless network. Access Points support "Infrastructure" networks as opposed to "Ad-Hoc" networks. The AP
is responsible for forwarding network to and from connected wireless devices and PC's.
Serial Interface
: Typically, the data loggers are connected to one of the serial interface connectors on the
Lantronix SGX 5150. The serial interface port support baud rates up to 921.6Kbps and RS-232 or Multi-
protocol RS-232/422/485. The default serial port settings are 9600 baud, No parity, 8 data bits, 1 stop bit and
no flow control.
