IMPORTANT
This manual is for GreenEye Monitors models with “WiFi / Ethernet Combination”module only (with or
without an XBee module). The picture in Figure 1 displays the “WiFi/Ethernet Module” (outlined in blue).

MISSION
The objective of this document is to establish a connection between a PC and the GEM allowing the
GEM firmware to be upgraded if needed and gaining access to the GEM Setup page. Tasks covered in
this manual are listed below.
Setting Communication Module to Factory Defaults. This provides a known IP address for initial
connection
Connecting a PC directly to the GEM for configuration purposes.
Establish a direct connection between a PC and the GEM. This enables the user to enter local
network information such as SSID, Password, etc., allowing the GEM to connect to a network
Connecting the GEM to a Network. Once the GEM is connected to a local network, the PC can
then connect to the same network
Connecting to the GEM’s Setup Interface. The setup interface is browser based. Once a PC
connects to the GEM via network, all GE settings may then be configured
Upgrading the GEM’s Firmware. A guide is provided to perform firmware upgrades to the GEM
STEPS
A typical setup procedure would consist of the following order of steps, although some scenarios may
differ.
1. Set communication module to factory default
2. Establish a WiFi connection between a PC and the GEM
3. Configure the ”SSID”, “Password”, etc. to create a WiFi connection between the GEM and a
local network
4. Connect the PC to the same network and establish a TCP/IP connection to the GEM over the
network
5. Upgrade the firmware if needed
6. Open the GEM Setup page with a browser
Once the GEM Setup page has been opened, then refer to the “GEM Configuration Manual” (Document
code: GEM-CFG) to proceed with setting up the GEM
REQUIREMENT
The “GEM Network Utility” version 4.2 or higher for Windows based PCs
For “Mac” or “Linux” users, a “Java” application is available for firmware upgrades, however
different instructions are required
THE COMMUNICATION MODULE
The WiFi/Ethernet module option for the GEM incorporates two methods of communication providing
the choice of a WiFi or Ethernet connection. Both options are integrated on a single module.

Typically, a connection to a local network is established allowing data to be sent to a local server or
remote host via internet.
START-UP SEQUENCE
When the GEM is powered up, the “Communication Status LED” (see Figure 2 on page 5) will remain
dark (off) for approximately 30 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 to amber.
COMMUNICATION STATUS LED
The communication status LED is a dual color “amber” and “green” type. When both LED are on, the
resulting color is yellow. The three LED states are:
Dark: The communication module is booting up.
Amber: The communication module is active but there is no connection.
Yellow (green +amber): The module is connected.
Figure 2
The picture in Figure 3 shows the “Communication Status LED”which consists of an amber LED and a
green LED together in the same package. The combined color is yellow when the amber LED and the
green LED are both lit.
Figure 3
RESET TO FACTORY DEFAULTS
The communication module factory reset provides a means of setting the GEM to a known IP address
and port. This allows a PC to connect to it in order to re-direct it to a local or remote network.
Factory reset can only be done with the communication module fully booted up which occurs roughly 30
seconds after the GEM is powered. This is apparent when the “communication status LED” comes “on”.
1. Make sure the “Comm Status LED” is “on”!

2. Locate the ”Factory Reset Push Button”switch on the edge of the module (see Figure 4) then
press it for approximately 6 seconds and release. (There will be no immediate LED response
when the switch is released).
3. After roughly 10 seconds, the communication status LED will go dark. This indicates that the
module is in the process of re-booting.
4. After approximately 30 seconds, the amber LED comes on. A few seconds after this occurs, a
wireless access point becomes available.
5. Use a PC with WiFi capability and search for wireless networks. The GEM will now appear as a
WiFi “Access Point” with a WiFi network name: “GreenEye_xx”, where “xx” are the two last
characters of the MAC address.
Figure 4
Proceed to the next chapter “Connecting Directly to the GEM” for instructions on connecting to the
GEM with the PC.

CONNECTING DIRECTLY TO THE GEM
IMPORTANT NOTE
This chapter describes the procedure for creating a WiFi connection between the GEM and a PC. The
main purpose of this connection is to configure the GEM to connect it to a network.
If a PC with WiFi capability is not available, an Ethernet connection may be used for this step, although
this method is a bit more tedious. Refer to Appendix A for instructions on using Ethernet for initial
configuration.
Make sure there is no Ethernet cable connected between the GEM and a network when conducting
the steps in this chapter.
FACTORY DEFAULT VALUES
Once the communication module has been reset to its factory defaults, a WiFi connection may be
established between a PC and the GEM.
The factory default settings are:
Set to Access Point (AP) mode
DHCP enabled. The server will assign an IP address to the PC, providing the PC is set to obtain an
IP address automatically
The SSID is “GreenEye_xx”, where xx is the last two digits of the MAC address
WiFi security mode “Open”
Local IP address: 192.168.2.2
Network setup port 80
GEM setup port 8000
CONNECTING TO THE GEM VIA WIFI
The goal is to create a connection between the PC and the GEM as shown in Figure 5.
Figure 5

Steps
1. Search for WiFi networks and click on “GreenEye_xx” to connect.
2. Open a browser and set the address to 192.168.2.2 and press “Enter”. A “Sign In” box should
come up prompting for a “User” and “Password”. If so, then skip to step 4.
3. If the browser did not connect to IP address “192.168.2.2” in the previous step, the PC may not
be set to “obtain an IP address automatically”. Modify the PC’s network settings to do so then
repeat the steps in this section. If you don’t know how to change this network setting, then
search “how to obtain an IP address automatically” on the internet for instructions for your
operating system.
4. A “sign in” box will prompt for a user name and password. Use “admin” for both.
A web page as displayed in Figure 6 will open. This is the interface used to setup the communication
module to connect to the Network.
Figure 6
NETWORK CONNECTION OPTIONS
Two options are available to connect the GEM to a network, “WiFi” or “Ethernet”.
WiFi Connection
This option consists of connecting to the network wirelessly. This method is usually preferred as long as
the GEM is within acceptable RF range of the WiFi Router it will be connected to.
Ethernet Connection
An Ethernet connection consists of connecting a network cable between the GEM and a network router
or hub. This method is preferred when a WiFi connection is impractical due to signal range or if a
dependable connection is desired.

WIFI CONNECTION TO A NETWORK
This chapter describes how to create a WiFi connection between the GEM and a local network. See
Figure 7.
CONNECTING THE GEM TO A NETWORK
The GEM can connect to a WiFi router or access point. This requires changing the GEM’s communication
module from its default access point mode (AP mode) to station mode (STA mode).
As most WiFi networks are security enabled, the SSID security type and passphrase will be required for
the network that we wish to connect to. Before starting the configuration, you should determine the
following information with regards to the network you will be connecting to:
The WiFi router’s SSID and Pass Phrase (WiFi password)
The gateway IP address
An available static IP address
The IP address or domain name of the data host.
