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.

Appendix C –Diagnostic Lights
The lights on the front of the SGX 5150 can be used for basic network troubleshooting:
WPS Status
Blink Pattern
WPS is enabled and on
Short, continuous
WPS has a profile error
Long, long, long, short, short, 2 seconds off, continuous
WPS has a timeout error
Long, long, long, short, short, short, short, 2 seconds off, continuous
(Table 2)
Note - For the above table, a “long” blink is 0.7 seconds of light followed by 0.3 seconds of no light. A “short” blink is a
light that is on for only 0.2 seconds and followed by 0.2 seconds of no light.
The diagnostic blink patterns reflect the highest priority fault condition. Also, the Diagnostic LED gives an
initial, identifying blink pattern to indicate the type of diagnostic information it will display. All power and other
non-network related diagnostic patterns begin with one long blink. All wired LAN related diagnostics patterns
begin with two long blinks. All WLAN-related diagnostics patterns begin with three long blinks.

Appendix F –Switched Power Control for Campbell Dataloggers
Campbell Scientific dataloggers include programmable power outputs, such as Switch 12 (SW12), which can
be used to control power to connected devices, such as the Lantronix SGX 5150.
(Figure 28)
SW12 provides a programmable output of 12 volts to the connected device and by doing so, the following can
be achieved:
•Power cycle the connected device, allowing a reconnection to the local Wi-Fi network.
•Reducing the power consumption of an entire unit by turning power on at specified times rather than
being continuously powered.
To use switch power control, the datalogger program must be updated and the device’s power inputs must be
rewired to connect to SW12 instead of the charge regulator.
Note − Devices that requires more than 1 amp of power cannot be powered through SW12. If a device
requires more than 1 amp of power,contact Canary Systems.
