1 INTRODUCTION
1.1 OVERVIEW
This manual provides instructions for establishing communication with a GreenEye Monitor (GEM)
equipped with “Wifi Only” option (model GEM-W).
1.2 OUTLINE
This section is a brief overview of the steps required to connect the GEM to a network and connect to
the GEM setup page. The purpose of this section is to understand the process before executing each as
explained in later chapters. The required tasks are:
Set the GEM to Access Point (AP) mode (Figure 1)
Make a Wifi connect directly between a computer and the GEM (Figure 2)
Change GEM network settings to connect to a network (Figure 3)
Connect the computer to the GEM via the network (Figure 4)
Upgrade the GEM firmware if required (Figure 5)
Access the “GEM Setup Page”
Each of these are illustrated and described briefly below. Each procedure is detailed in subsequent
chapters.
Set GEM to AP Mode
Figure 1
The first task is to set the GEM to “Access Point”(AP) mode. This make the GEM appear as a typical WiFi
router does. This provides a known SSID (Wifi network name) and IP address allowing a PC to connect to
the GEM.

Introduction
Page 4
Connect to the GEM with a Computer
Figure 2
A computer connects directly to the GEM in AP mode using the same method used when a PC connects
to a WiFi Network. See Figure 2.
Connect the GEM to the Network
Figure 3
The PC opens the GEM setup page. The setup page is used to change the GEM’s Wifi settings to connect
to the network’s WiFi router. See Figure 3.
Connect the Computer to the GEM via the Network
Figure 4
Once the GEM is connected to the network, any computer on the network can communicate with the
GEM. See Figure 4.

Introduction
Page 5
Upgrade Firmware if Required
Figure 5
If firmware upgrade is required, a computer can load the new firmware to the GEM through the network
connection.
1.3 REQUIREMENT
A computer with Wifi
Wifi Router or Network Access Point
The router’s SSID (wireless network name) and security password
“GEM Network Utility”software ( http://brultech.com/software )
“GEM Firmware Upgrader” software and firmware file (if firmware upgrade is needed )
( http://brultech.com/software )
The GEM needs to have “COM”firmware version 1.70 or greater installed as it incorporates a built-in
web interface to setup the GEM parameters. This also includes a means of setting up the Wifi
parameters. Any GEM purchased after January 15, 2013 would qualify as having compatible firmware.
If the COM firmware is older than version 1.70, an upgrade will be required. Firmware version 2.40 or
better is recommended.
If you do not know the firmware version currently installed on the GEM, it can be acquired using the
GEM Network Utility software using the “Get GEM Info”button.

Set GEM to Access Point Mode
Page 6
2 SET GEM TO ACCESS POINT MODE
Figure 6
2.1 ACCESS POINT MODE
If the GEM is being setup for the first time, it needs to be set to “Access Point” (AP) mode. This will set it
with factory default settings. This allows a PC to connect directly to the GEM. Once connected the GEM
can be setup to connect to a network WiFi router.
2.2 TEST FOR AP MODE
The GEM may already be in “AP” mode, since this is the default setting when shipped. This can be tested
by searching for Wifi connections. If a network called “GreenEyexxx” (where xxx is the GEM’s partial
serial number) is present then connect to it and skip to the chapter “Connect Computer to the GEM” on
page 8.
2.3 SET TO AP MODE
The default Wifi settings are obtained by using a key sequence involving the use of the recessed push
button switch located at the bottom of the GEM enclosure. See Figure 6 for switch location.
Follow the two steps below:
1. Press and maintain the PB switch until the GEM’s “System” LED glows yellow*then release it
immediately.
2. Notice the following GEM LED sequence:
oRed LED flashes on-off three times
oGreen LED flashes on-off three times
oYellow*LED flashes on-off three times
oLED returns to normal operating state
If for some reason this didn’t happen repeat the above procedure.
*Note: “Yellow” is the combined color resulting from the “System” dual color LED glowing red and green at the same time.
The cover’s light pipe combines both colors to provide a yellow glow. With the GEM’s cover removed the light is not
combined through the light pipe, therefore the two discrete colors (red and green) will be seen on the system LED.

Set GEM to Access Point Mode
Page 7
The purpose of the procedure described above is to get familiar with the sequence of LED flashes. No
changes will occur as a result of performing those steps.
In order to set the GEM’s WiFi module to its default values, repeat the two steps described above except
this time, during the sequence where the red LED flashes three times, briefly press and release the PB
switch. This must be done anytime during the red flash sequence but before the next sequence begins.
If for some reason you missed pressing the PB during the red sequence, allow the entire sequence to
complete then try again. It is important not to press the PB switch during sequences other that the red
sequence since doing so will execute a different function.
After this process is completed, the LED sequence will then change to a different flashing pattern as the
GEM re-configures the Wifi module to default settings. This process will last approximately 18 seconds.
Once the changes to AP mode has completed, the “Com LED” (see Figure 7) will flash amber rapidly and
green slowly. This is an indication that the GEM has successfully been set to AP mode.
2.4 DEFAULT AP MODE SETTINGS
When the GEM’s Wifi module is set to its default settings it will have the following settings:
Mode:
Access Point (AP)
SSID:
“GreenEyexxx” (where xxx is the GEM partial serial number)
Security:
Open (no security)
Local IP Address:
1.2.3.4
Local Port:
80
2.5 IMPORTANT NOTE
When the GEM’s Wifi module is in “AP” mode, it sometimes exhibits connections issues such that if a
connection is closed, it may have trouble reconnecting. For this reason, it is recommended to
immediately complete the procedures in the next two chapters to redirect the GEM to a network after
the initial AP mode connection. Once the GEM connects to a network there is no need to worry about
this issue.
If connection issues are experienced while connected in “AP” mode, try cycling power to the GEM. If this
doesn’t work, use the PC to disconnect from the “GreenEye”WiFi network then reconnect.

Connect Computer to the GEM
Page 8
3 CONNECT COMPUTER TO THE GEM
3.1 PURPOSE
Now that the GEM is in AP mode, our goal is to make a Wifi connection with the GEM so that its network
parameters may be modified to have the GEM connect to a local network. The changes are done with
the GEM’s web setup interface using a browser.
3.2 PROCEDURE
Figure 7
The GEM is in Access Point (AP) mode and will appear as a wireless network named “GreenEyexxx” (xxx
is the GEM’s partial serial number) when searching for Wifi networks with a computer. If you are not
familiar with connecting to a Wifi network, consult your computer’s manual or perform an internet
search using the computer’s operating system as a keyword.
After doing a scan for Wifi networks and discovering the GreenEye, simply select “Connect” to establish
a Wifi connection (Figure 8). No password is required since there is no security enabled at this time.
Figure 8 shows an example of a connection made to “GreenEye118” in “AP” mode.

3.3 WEB SETUP PAGE
Once the Wifi connection between the computer and the GEM is established, open a web browser and
enter the following IP address “http://1.2.3.4”. The browser should display the GEM’s “Enter Setup”
page (Figure 9).
Figure 9
If this page is not displayed, try refreshing the browser. It may take a couple of tries to properly display
this page, but once the GEM is in setup mode, the web interface will run smoother.
The goal is to enter the GEM’s “Setup Mode”. This will provide the capability of modifying the network
settings allowing redirection of the GEM to a local network.
1. Click “Enter Setup Mode”
2. Click “Network” Menu (Figure 10)
