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.

Required Equipment and Software

To configure your SGX 5150 and test its operation you need:

1. SGX 5150 Serial Device Server (normally installed in the data logger enclosure)

2. A USB to Serial Adapter, Lantronix Serial Port adapter cable

3. Computer with a Wi-Fi network adapter (most laptops have built in Wi-Fi and USB Wi-Fi adapters are

readily available to add Wi-Fi capability to a desktop)

4. Data logger (normally installed in the data logger enclosure)

Note

−

The data logger system should have the serial cable which connects the SGX 5150 serial port to the data

logger serial port already installed.

Configuring the SGX 5150

This Application Note describes how to configure the SGX 5150 to operate in an infrastructure network. It does

not cover configuring for an ad-hoc network.

Gather Information about your Wireless Network

Before you can configure the SGX 5150 you need to understand the wireless network that you are connecting

the SGX 5150 to. Work with your systems administrator to obtain this information, specifically:

SSID

Example: MyNetworkName

Provided by your IT Department

Passphrase

Example: SecretPhrase

Provided by your IT Department

Security Type

Example: WPA2, WEP

Provided by your IT Department

IP ADDRESS

nnn.nnn.nnn.nnn

Assigned by your IT Department

SUBNET MASK

nnn.nnn.nnn.0

Assigned by your IT Department (Typically 255.255.255.0)

Default Gateway

nnn.nnn.nnn.nnn

Assigned by your IT Department

(Table 1 - Note: ‘n’ can be any digit 0 to 9)

Note

−

The SGX 5150 does include support for DHCP but it is NOT recommended to use this as IP addresses can be

re-assigned which will require MultiLogger



configuration to be updated. Names can be assigned to an IP address,

and MultiLogger



does support name resolution of IP addresses, however this requires additional configuration that is

beyond the scope of this Application Note.

Configuration over a Serial Port

The following steps are for configuration of the SGX 5150 over the serial port. This configuration method does

not require extra software or network access. If you have access to the network you want to configure for,

please see Appendix D for an alternative method.

1. In order to start the configuration, first set SGX 5150 to Factory Defaults; See Appendix A.

2. Turn off power to the SGX 5150.

3. Open the terminal program HyperTerminal (or similar program like PuTTY) and set serial communications

to: (9600, 8, N, 1, No Flow)

▪Baud rate: 9600

▪Data bits: 8

▪Parity bit: None

▪Stop bit: 1

▪Flow control: None

4. Set your terminal program to the proper COM port (Check Device Manager).

5. Connect the USB-Serial Adapter to a Null-Modem cable. Plug the Serial Cable adapter into Serial 2 (use

Serial 1 if configuring for an MLGPS) on the SGX 5150 and the DB-9 end to the Null-Modem cable.

6. In the terminal window, Hold down the “!” key (shift + 1).

7. Turn on the power to the SGX 5150.

8. Keep holding the “!” key for about 10 seconds until a “!” character appears in the terminal window.

9. Release the “!” key and type “xyz” within 5 seconds.

10. The SGX 5150 prompt should appear in the window:

(Figure 3 - Terminal Window)

Enter the commands as shown below. Black text is the command prompt. The red text indicates commands

you enter. Blue text indicates command responses from the SXG 5150. For brevity, not all SGX 5150

responses are shown.

Connection is complete once WLAN and SIGNAL lights on the SGX 5150 turn on, this may take a few minutes.

Using the Lantronix SGX 5150 Serial Device Server

Confirm Connection

The SGX 5150 should now be configured for your wireless network. This can be tested by opening a web

browser and typing the SGX 5150 IP address into the address bar. When prompted for a username, enter

"admin". The password, for devices manufactured after January 1, 2020, is the last 8 characters of the Device

ID, or for older units use “PASS”. Once the user name and password have been entered click OK. If you see

the SGX 5150 homepage (shown below), you have correctly configured your SGX 5150.

(Figure 4 - SGX homepage that displays when connected and properly configured)

Testing SGX 5150 Configuration

To test the operation of the Serial Device Server with a CR300 (or similar) Control Module, open MultiLogger

and update the IP:Port configuration for the new device, CR300 example shown below.

Connect the datalogger’s Serial Port to Line 1 on the SGX 5150.

Note

−

Be sure to use the settings utilized with your infrastructure.

The ports for the Serial Ports are as follows:

▪Serial Port 1: 10001 (Serial Port 1 is Line 1 on the SGX 5150)

▪Serial Port 2: 10002 (Serial Port 2 is Line 2 on the SGX 5150)

Press Save in MultiLoggerwhen settings are updated.

(Figure 5)

Double-click the node, CR300_1 in the example above, or select it and press the Logger button, to open the

Logger form.

Using the Lantronix SGX 5150 Serial Device Server

Press the Monitor button on the Logger toolbar to start the Monitor mode.

This initiates a socket connection to the device and attempts to start the Monitor mode.

If successful, the Datalogger Clock starts updating to indicate successful communication.

(Figure 6)

Appendix A –SGX 5150 Reset

To reset the SGX 5150 and restore the manufacturer default settings: Press the Reset button as shown in the

figure below for 6 seconds. The SGX 5150 configuration automatically reboots as the button is released.

(Figure 7)

Appendix B –Troubleshooting PC Wireless

If your PC’s wireless adapter will not connect to the SGX 5150, then these steps may help resolve the lack of

connectivity:

1. After the device connects, go to the PC’s Network and Internet settings.

(Figure 8)

2. Right-click on your Wi-Fi adaptor and select Properties.

(Figure 9)

3. In the Wi-Fi Properties, select Internet Protocol and select Properties again.

(Figure 10)

Using the Lantronix SGX 5150 Serial Device Server

If Use the following IP address is selected, then select Obtain an IP address automatically and skip to step

5. If Obtain an IP address automatically is selected, then proceed to the following step.

(Figure 11)

4. Select Use the following IP address and enter a Default gateway, Subnet mask and unique IP address

for your network. (Example shown in Figure 11)

(Figure 12)

5. Then click on OK.
