INTRODUCTION
This manual describes the procedure for setting up communication for a GEM having the WiFi/Ethernet option (GEM-
WE).
THE COMMUNICATION MODULE
The GEM has a separate communication module with its own dedicated processor to provide WiFi or Ethernet
communication. Because of this, there will be two setup web interfaces:
WiFi/Ethernet setup page
GEM setup page
START-UP SEQUENCE
The GEM is powered up when the 5VDC power adapter is
plugged into an outlet and to the GEM (Figure 1).
When the GEM is powered up, the “Communication Status LED”
(Figure 2) will remain dark (off) for approximately 6 seconds.
This is the time required for the communication module to boot
up and create or join a network. Once the module is booted the
LED will turn AMBER. If there is a WiFi connection to the GEM,
the LED will change from AMBER to YELLOW.
The “System Status LED” (Figure 2) will be GREEN unless a PT
is not connected. If there is no PT signal this LED will flash
RED on-off continuously. Note: The PT signal is not required
when setting up the GEM communication.
COMMUNICATION STATUS LED
The “Communication Status LED” (Figure 2) will glow AMBER (orange) or YELLOW.
Dark: The communication module is booting up.
AMBER: Communication module is active but there is no WiFi connection although there may be an Ethernet
connection.
YELLOW: The module has a WiFi connection in AP or STA mode.
Note: If using Ethernet cable connection, the LED will remain AMBER regardless of whether or not there
is a connection.

HARDWARE
The WiFi antenna connector
The antenna screws on to the antenna connector. It is a 3dBi RP-
SMA type. If the antenna location is in a bad area and range or
interference issues arise, you can order an antenna extension to
position the antenna for optimum signal.
The Ethernet cable connection
The Ethernet jack is a standard RJ-45 type.
Note: There are no activity LEDs on this jack
Factory default reset switch
This push button switch is used to reset the WiFi/Ethernet
settings to its factory default values. Push the switch button for
approximately 5 seconds to reset.

WiFi Security

WIFI SECURITY
By default the GEM’s WiFi Access Point (AP) is unsecured. This is equivalent to having a network router with no
password protection. Once the GEM has a connection to your network via WiFi or Ethernet cable, your network would
be open to anyone within WiFi range since the open AP is bridged to your network. This issue is resolved by enabling
WiFi security.
HOW TO SETUP SECURITY
Note: Although the following steps refer to using a personal computer
(PC), a Laptop, Tablet or Smart Phone may be used instead.
The GEM creates WiFi network called “GreenEye_xx” where ”xx”may
be any two characters. The goal is to connect to the GEM’s access point
(AP) with a PC. The steps are described below:
1. Make sure the WiFi antenna is installed on the GEM. Connect
the 5Vdc power supply to the GEM (Figure 4). After six seconds
the Communication LED will come on and glow AMBER
(orange). It is not required to have the PT (12Vac wall
transformer) plugged in at this point. If the PT is connected, the
“System” LED will glow GREEN otherwise it will be flashing RED.
2. Use the PC to search for a wireless network named
“GreenEye_xx” (where the two “xx” could be any two
characters). See Figure 5. If you have more than one
WiFi/Ethernet GEM operational, you will probably see more
than one “GreenEye_xx” network. If this is the case, unplug the
other GEM(s) until you’re done with the current GEM. Connect
to this WiFi network. Once you have established a connection
the Communication LED of the GEM will change from AMBER to
YELLOW. Your device is now connected to the GEM.

3. Using your connected device, open a web browser and enter
the IP address “1.2.3.4” (you may need to use “http://1.2.3.4”).
You will be prompted for a Username and Pass Phrase. Use
“admin” for both. See Figure 6.
4. On the side menu (left), click “AP Interface Settings”. This will
open the “AP Interface Setting” (Figure 7). If you wish to
replace “GreenEye_xx” with a different SSID (1), you may
enter the new SSID in this field. The new SSID must not have
any spaces or special characters. In this example
“Sub_Panel_GEM” was used. This is the SSID that will be
displayed when you search for wireless networks. Click “Apply”
(2). Disregard the “Set Successfully” page (Figure 8). Click “AP
Settings” from the menu.
5. The screen on the right shows the “AP Interface Settings”
screen once again. Set the “Security Mode” to “WPA2-PSK” (1).
Set the “WPA Algorithm” (2) to “AES”. Enter a password (3).
Remember to obey the rules for password such as no spaces or
reserved characters. The password is also case sensitive. Click
“Apply”.
6. Click “Device Management” (Figure 10)from the menu (1).
Click “Restart” (2). The GEM will now save the changes and re-
boot the communication module. Wait approximately 30
seconds. If you modified your SSID search for the new SSID and
connect to it. Remember that you will now need to use the new
Pass Phrase.
The GEM now has a secure connection. BEWARE: Anytime the GEM’s WiFi Ethernet module is reset to the factory
default settings, the WiFi security will reset to unsecure!

WIFI CONNECTION
If you are connecting the GEM to the network using an Ethernet cable, skip this section and proceed to the “Ethernet
Connection” chapter.
Make sure you do not have an Ethernet cable connected when using WiFi connection. Having completed the Security
Setup, you should be connected to the GEM with your device (PC, Laptop, Tablet or Phone). If you are not connected,
search the SSID that you have given the GEM and connect to it.
WIFI CONNECTION BETWEEN GEM &NETWORK
1. Open a web browser and enter the IP address “1.2.3.4” (you
may need to use “http://1.2.3.4”). You will be prompted for a
Username and Password. Use “admin” for both. (Figure 13)
2. Refer to Figure 14. On the main page, select “STA Mode”(1)
then click “Apply” (2). You will be prompted to select the
“Device Management” page and to restart the module. DO
NOT DO THIS AT THIS TIME!
3. On the side menu (left), click “STA Interface Settings” (1).
This will open the “STA Interface Parameters” box (Figure 15).
Click “Search” (2). A “Site Survey” window (Figure 16) will
open displaying the WiFi network(s) in range. Find the
network you wish the GEM to connect to. Click the radio
button to the left of the desired network. Click “Select” at the
bottom of the site survey page. A box will open prompting
you to “Please Input Key!”. Click OK.

4. Refer to Figure 17. Enter the “Pass Phrase”(1) which is the
password of the WiFi network you are connecting to. Set the
encryption to “AES” (2). Although “TKIP” is shown in the site
survey, TKIP does not function properly. Click “Apply”(3).
5. After clicking “Apply”, the window in Figure 18 will be
displayed. Click “Device Management”
6. The “Device Management” page is displayed in Figure 19. Click
“Restart” and proceed to the next step. Wait approximately 30
seconds for the module to save settings and reboot.
7. Connect your PC to the same network the GEM is now
connected to. Doing so will automatically disconnect your
device from the GEM AP. Once you have completed this, verify
that the “Communication LED” of the GEM is glowing YELLOW.
This indicates a successful WiFi connection between the GEM
and your network. If the LED is glowing AMBER, that would
indicate that the GEM has not connected to your WiFi network.
Skip over the next chapter (Ethernet Connection) and proceed to “Discover GEM’s IP Address” chapter.

ETHERNET CONNECTION
Skip this chapter if you are using WiFi to connect the GEM to the network!
This section describes how to connect the GEM to the network using
an Ethernet connection instead of WiFi. (see Figure 21)
Do not attempt to connect to the network using Ethernet and WiFi at
the same time as this will cause strange behaviours.
Note: An Ethernet cable is not included in your kit because the
required length will vary based on the distance between the GEM and
your network router.
ETHERNET CONNECTION TO THE NETWORK
If the GEM’s WiFi/Ethernet module is set to its factory default values, connecting it to a router via Ethernet cable will
allow the router to detect the GEM and assign it an IP address on the network.
1. Plug an Ethernet cable between the RJ-45 jack on the GEM and your network router
2. Make sure the GEM is powered up. The communication LED should be orange
The GEM should now be connected to the network.
Proceed to the next chapter.

the router

Discover GEM’s IP Address
© Brultech Research Inc. 11 www.brultech.com
DISCOVER GEM’S IP ADDRESS
At this point, the GEM is connected to your network either via WiFi or Ethernet cable.
There are many options for discovering the GEM’s IP address. Two of them are explained in this chapter. Additional
options are described in Appendix A.
Windows OS: Download and install the Brultech Device Discovery program from:
“https://www.brultech.com/software/files/downloadSoft/Brultech_Device_Discovery_130.exe”
iOS, Android, Linux or Mac: Non-Windows system or smart phone you can use the free “Fing” app.
Fing for Windows, Linux and OSx: https://www.fing.io/download-free-ip-scanner-desktop-linux-windows-osx/
Fing for iOS and Android: https://www.fing.io/
Windows User
1. Install and run the Brultech Device Discovery program
(Figure 22).
2. Click “Search”(1).
3. Double-click “GEM Network Setup”(2) from the found
devices.
4. Once the browser opens, use “admin” for both the
User and Password.
Non-Windows User
1. Install and run the “Fing” app (Figure 23).
2. Connect you PC, tablet or phone to the same network the GEM is connected to.
3. Perform a network scan using Fing.
4. Look for a device with MAC address beginning with “AC:CF:” or with the name
“Hi-flying Electronics Tech”. Make note of the IP address for this device.
5. Open a browser and enter the IP address.

CONNECT TO DASHBOX
If you are connecting to a data host other than the DashBox, skip this chapter and proceed to “Connect to Data Host”
DISCOVER DASHBOX IP ADDRESS
If it’s not feasible to connect the GEM to the DashBox using RS-232 communication
then the next option is to connect using WiFi or Ethernet cable.
The DashBox manual describes how to find the IP address for the DashBox. Ideally
the DashBox has been set with a “static” address meaning that the router will not
change this IP address.
If you have installed the Brultech Device Discovery program you may use it to
discover the DashBox’s IP address. If you used the “Fing” app you may use it also.
Other options are described in Appendix A.
Fing
Figure 24 shows a scan done using the free “Fing” app running on an iPhone.
Notice that a DashBox was discovered and the IP is listed on the left (192.168.2.79)
in this case. The port used to send data to the DashBox is port “80”.
Device Discovery program
Figure 25 shows a “Search” done using the free “Brultech Device Discovery”
program.

SEND DATA FROM GEM TO DASHBOX
We now need to configure the GEM so that it has the following information:
IP address of the DashBox
Packet format and send interval to the DashBox
Data post header information
1. If you are using the “Brultech Device Discovery” program
(Figure 26), click “Search” then double click the GEM device
that was found. A browser will automatically open. If using
“Fing” then open a browser, enter the GEM’s IP address and
add the suffix “:8000” to access the GEM Setup page via
port 8000. Ex: “192.168.2.23:8000”.
2. Enter the setup page and click “Network” from the menu
(Figure 27).
3. Enter the IP Address for the “DashBox” which was obtained in step 1. Enter “80” as the port number. Click
“Save”. Wait 30 seconds. The GEM data is now sent to the DashBox from the GEM.
4. Re-Enter the GEM setup page. Click “Packet Send”from the menu. Make sure that it is configured for the
following:
a. Realtime = “on”.
b. Primary Packet Format = “3. HTTP GET”.
c. Packet Send interval “5” or greater.
5. If you modified any of the above parameters, click “Save”.
6. Select “Data Post” from the menu. Click the “DashBox / Standalone Software” button.
7. Enter the DashBox IP address in the “URL Address” field.
8. Leave the “URL Extension” with the preset value
9. Click “Save”
This completes the setup. The GEM is now sending packets to the DashBox over the network.

Connect to Data Host
© Brultech Research Inc. 14 www.brultech.com
CONNECT TO DATA HOST
If you are using a DashBox webserver skip this chapter.
WHAT IS A DATA HOST?
The “Data Host” is the device or website that will receive packets from the GEM. You can make the comparison of a
Data Host to a network printer. When your PC sends a document to your network printer, it needs to know the printer’s
IP Address and Port. This was done when you initially setup the printer. The same principle applies here. The GEM send
energy data instead of printer data and the Data Host stores the data information whereas the printer prints it.
Data Hosts Examples
1. DashBox Webserver (Brultech)
2. Standalone Software (free from Brultech) running on a local Computer
3. “BTmon” running on a local PC or Single Board Computer (SBC). BTmon is free courtesy of Matthew Wall who
has done an excellent job! This option is for more computer savvy people.
http://lancet.mit.edu/mwall/projects/power/btmon-howto.html
4. Emoncms running on a local PC or Single Board Computer (SBC)such as Raspberry Pi or running on a remote
web site. This is an open source program which requires computer savvy.
https://github.com/emoncms/emoncms
5. Hosting site such as http://mysolarstats.com or http://smartenergygroups.com There is a charge for these
services.
Although the GEM is now connected to the network, it needs to send its packet data to a specific device on the network
or over the internet. This requires knowing the IP address or URL of the host device including the port used. If you have
a system which includes a DashBox, we would set the IP address and port to that of the DashBox.
Data Host
If you are sending data to a third party host over the internet, contact the host to acquire their URL. For example
“smartenergygroups.com” requires data packet to be sent to “api.smartenergygroups.com”.
If you are using a local computer to host, you can use any of the four options listed in Appendix A find the host
computer’s IP address or go to the host computer and view its IP address from its network settings.
SETTING IP AND PORT
At this point, you should have the IP address of the host. The port will be Port 80 for almost all situations.
Setting the IP of the data host can only be done using the GEM setup page. Accessing the GEM setup page has been
described in the previous chapter.
Refer to the screenshot below to set the IP address (or URL) and port.

Connect to Data Host
© Brultech Research Inc. 15 www.brultech.com
1. Open the GEM setup page
2. Click “Network” from the menu (Figure 28)
3. Enter the IP address or URL in the corresponding field. In this example it is “192.168.2.41”. If you are sending to
“api.hostsite.com”(fictional site), you would enter api.hostsite.com in this field.
4. Enter the port number. This is typically port 80 especially if sending data over the internet
5. Click “Save” and wait approximately 30 seconds
This will cause the GEM to direct packets to your data host. The GEM manual explains how to configure the “Packet
Send” and “Data Post” for the specific data host used.
1. Re-Enter the GEM setup page. Click “Packet Send” from the menu. Make sure that it is configured for the
following:
a. Realtime = “on”.
b. Primary Packet Format = (dependent on data host requirement)
c. Packet Send interval “5” or greater.
2. If you had to modify any of the above parameters, click “Save”.
3. Select “Data Post” from the menu. Click the “DashBox / Standalone Software” button.
4. Enter the DashBox IP address in the “URL Address” field.
5. Leave the “URL Extension” with the preset value
6. Click “Save”
This completes the setup.

ADDITIONAL SECURITY OPTIONS
DISABLE AP
You have the option to disable the AP completely when connected to the network using WiFi. Although this is not
recommended, it may be needed in certain situations.
This option is only functional if you are connected to the network using WiFi. It allows you to disable the Access Point
altogether. This option should only be used in extreme cases and generally not recommended!
If you choose to disable the AP mode, you will not be able to connect to the GEM’s Access Point any longer until a
factory reset is done which will reset all your network connections settings.
1. Connect to the GEM Setup Page. This is different than the WiFi/Ethernet setup page accessed previously. This is
done by using the same IP address in your browser and adding “:8000” at the end if the address. For example if
the browser was set to IP address was http://192.168.1.45, use http://192.168.1.45:8000. You should get the
screen shown in Figure 29. You may need to refresh the browser a couple of times.
2. Click “Enter Setup Mode”. The page should look like Figure 30.
Figure 29

TROUBLESHOOTING
ACCESS POINT (AP)
Cannot see “GreenEye_xx” when looking for wireless network.
Remember that the “xx” after “GreenEye_” may be any two characters representing a HEX value and will not be “xx”
You are out of the GEM WiFi range. Move your computer/tablet/phone closer to the GEM and search again.
Antenna not installed or damaged
Channel conflict with other WiFi access point. Cycle power to the GEM to allow it to find a quiet channel.
The SSID for the Access Point was changed or the AP was set to “Hidden”. Reset WiFi/Ethernet to factory
defaults.
AP has been disabled in the “ADV” (advanced) section of the GEM setup page. Connect to the GEM, access the
GEM Setup page, select “ADV” from the menu, click “AP on” button. If you cannot connect to the GEM over the
network, you may need to reset to factory defaults to connect to the AP.
WIFI CONNECTION TO NETWORK
Site search does not show desired network
Router’s WiFi signal is out of range with the GEM
Too many WiFi access points detected. The site survey will list the networks in order of channel numbers. There
are two options to resolve the issue:
oManually enter “SSID”, security, etc.
oAccess the router and set it to use WiFi channel 1
No WiFi connection to the router.
You are using the wrong security type to connect to the router.
Verify the Pass Phrase (password). Remember that it is case sensitive.
If using TKIP algorithm, try AES or vice versa.
The router has been configured to allow connection with devices of specified MAC address. Connect to the
router setup and investigate.

Troubleshooting
© Brultech Research Inc. 19 www.brultech.com
ETHERNET
No Ethernet connection to the router.
By default, the GEM is set to DHCP which means it will wait for the router to assign an IP address.
Defective Ethernet cable or not plugged in all the way. Routers have LEDs indicating Ethernet connection for
each Ethernet jack. If the LED is dark, try a different router channel or Ethernet cable.
If the router LED for the channel you are using is active then perhaps there is a problem with DHCP. Try assigning
a static IP address. In the setup page, select “STA Interface Setting” from the left menu. Select “Static (fixed IP)”
from the drop-down menu. Enter your router’s IP address in the “Default Gateway” and “DNS” fields. Use
“255.255.255.0” for the “Subnet Mask”. For “IP Address” us the first three octet as your router the use a high
value below 254 as the fourth octet. For example if your router’s IP is “192.168.1.1” then set your IP address to
“192.168.1.99”. Don’t forget to “Save” and “Restart” after changing those settings.
TCP/IP
The Data Host device is not receiving packets
Verify that the GEM is sending packets. The red system LED should flash briefly at whatever packet send interval
the GEM is set to (typically 5 or 8 seconds). If there is no red flash then realtime is turned off or the GEM is stuck
in setup mode. If stuck in setup mode you can cycle power to the GEM and it will begin sending packet after 30
seconds of reboot.
If the GEM is sending packets as indicated by the brief red LED flash at regular interval, then you may be lacking
a TCP/IP connection. This may be due to using an improper IP address or port.
