1.5.2 I/O connections on rear panel
See section 5.1.1 on page 15 for a description of the I/O connections on the G5’s rear panel.
1.5.3 Internal connections
See section 5.1.2 on page 15 for a description of the G5’s internal connections.
1.5.4 Restore factory settings
If desired, you can clear G5’s entire current configuration at any time and return the settings to the factory
default values. To do this:
•Press and hold the Act button on the front panel for at least 20 seconds, until all three status
LEDs are on. Then release the button. The unit will restart with factory settings.
•This procedure also returns the system user name and password to their original default values
of “admin” and “admin”.
1.5.5 Booting into bootloader mode
Bootloader mode allows you to perform system software upgrades and also to upload a previously saved
configuration.
In case you need to use the bootloader mode, use the “Switch to bootloader” button in the Configuration
screen on the web interface (Figure 2).
Figure 2: Bootloader mode button
Another method for entering bootloader mode is to press and hold the Act button on the front panel, and
then press the Reset button right next to it, or just plug the power in while holding the Act button.
In bootloader mode G5 receives its IP address from DHCP server. If no address is received, G5 uses the
default IP address: 192.168.0.198.
When G5 is in bootloader mode and has received an IP address from DHCP, the green status LED (see
Figure 1) blinks slowly. If the default IP address is being used (after a timeout), the yellow status LED will
also be blinking. During file upload the LEDs will also blink; the rate at which they will blink depends on the
file type.
Note: if you boot the device to bootloader mode (normally for performing updates or restoring user
settings), but don't log into the web interface of the device for 5 minutes, the device automatically restarts in
normal operation mode.
If the G5 unit always boots in to the bootloader, this means that the main software is corrupt. You will need
to update the software file again.

2. INSTALLATION
The initial configuration of the device is fully performed through the web interface, and therefore the
installation begins with connecting it to the local network.
2.1 Physical setup
1. If you plan to use any of the I/O connectors, you must prepare all the necessary wires and sensors in
advance, and make sure they can reach the device. Connect all wires to the appropriate connectors,
according to the information in the relevant sections of this user guide. (See chapter 5 for information
on the physical connections.) After making the connections, close the G5’s top cover.
2. The G5 can be secured in a 19" rack using the provided accessories. In any case, the G5 unit must
remain fully accessible, front and rear.
3. Connect an Ethernet cable to the RJ45 connector marked LAN on the front panel.
4. Connect input power to the plug on the rear of the unit.
2.2 Access the web interface setup
1. When switched on for the first time, the device attempts to acquire an IP address automatically from
DHCP on the network. In the case that there is no DHCP server available in the network – for
example, when you are connecting the G5 directly to a computer – or in any other case of failure to
set the IP address automatically, the device falls back to the default address of 192.168.0.198, subnet
class C. This process can take up to one minute.
2. When configuring the G5 through a direct connection to a computer, the “network segment” (the first 3
nodes) of your computer’s IP address must match the network segment of G4’s default IP address.
So, change your computer's IP address to 192.168.0.100 and subnet mask to 255.255.255.0.
Remember to return your computer to its original IP settings when you're done, otherwise this may
cause issues on your LAN.
3. You can find the G5 on computer network by running the Discover.NET software, which is compatible
with Windows XP and later Windows releases. Discover.NET can be downloaded by navigating to the
web page at “http://www.gamatronic.com/G5.html” and selecting the icon “Download Discover.net”.
The software is very easy to use, and it lists all Gamatronic devices in the current subnet.
4. Type the device's IP address in to web browser's address bar and press enter. You should see the
main web interface screen. This is the place to begin the configuration.
Figure 3: The main web interface screen
See chapter 6 for further details on the software configuration process.

5. All data related to the current informational or configuration page is shown in the middle of the screen.
6. System-wide conditions shown in the status bar can include cellular modem alarms, page refresh
information and so on.
3.1 Dynamic updates
The web pages are dynamically updated every 3 seconds. This auto-refresh process stops after 5minutes
of no mouse usage so as not to create unnecessary network traffic, and a message will be shown in status
bar (item 6 in Figure 3). When the page has stopped refreshing data, it will still display the last information
received on the screen. Keep in mind that that this information may already be stale.
To restore the dynamically updated connection, just refresh the page in your browser.

3.2.1 UPS / Power System
To monitor a UPS or other power system, a serial connection to the device in question must be established.
This is done by connecting the device to be monitored to the serial connector on the G5’s rear panel, and
configuring the connection in G5, using the “Serial” option in the “Configuration” menu.
When UPS monitoring is thusly enabled, the “UPS” menu option displays the UPS’s status and general
information. The “Measurements” and “Commands” options display additional information, and enable the
user to send commands to the unit, to switch it on or off, or to run a test, and so on.
Be aware that the information displayed and the commands supported depend on the specific UPS or
power system model. Not all UPSs support every possible command.

4. ADDITIONAL FEATURES
4.1 Cellular modem
The presence of a cellular modem is an optional feature of G5. With a cellular modem, G5 can send
notifications of alarm conditions to your mobile telephone, using SMS. You can also use SMS to query G5,
which will send you responses with real-time system data.
Replies to cellular queries will be sent only to registered recipients. The process of registering a recipient is
described in section 6.9 “Define a target for alarm notifications”. The recipient’s phone number must be
entered when defining the notification target.
All cellular data requests are read-only.

kWh Actual kilowatt-hour counter values.
4.2 Automated shutdown of computers
If a UPS is being monitored by G5, and that UPS is providing power to computers, you can instruct G5 to
shut down any of those computers in an orderly fashion in the event of a prolonged ac input failure, before
the UPS’s battery is exhausted. To achieve that you must install Shutdown Agent software on the
computers to be shut down. The Shutdown Agent can be downloaded through a link on the remote
shutdown configuration webpage (see section 6.7), or can be obtained from your G5 dealer. Use the same
configuration webpage to configure remote shutdowns.
Remote computer shutdown can also be achieved through special dedicated software installed on one of
the servers. Such software monitors the UPS through SNMP, and can be configured to send appropriate
shutdown signals to specific servers in response to a specific alarm condition. Such software may provide
more shutdown options.

4.3 The bootloader
Bootloader is a separate software program that runs before the main program is loaded. It lets the user
upgrade the main software version when fixes or new features are released. Bootloader mode is also used
to restore a previously saved configuration. In normal conditions, the system boots directly in to the main
program, so the user will not see the bootloader in action unless it is run manually.
There are two ways to put G5 into bootloader mode:
•Reset (or power on) the device while pressing the "Act" button;
OR
•Press the bootloader button in the web interface "Configuration" webpage (see Figure 2).
In both cases, the unit will switch on in bootloader mode with the user-defined IP setting (see section 6.1
“Network configuration”). By default, the unit then automatically attempts to receive a DHCP address.
Failing this it will use the static address (as found in the “Network > configuration” screen). The default
static address is 192.168.0.198 class C. The unit will then be discoverable with Discover.NET software
within a given subnet (broadcast).
After 5 minutes in bootloader mode without user activity, bootloader exits (try to run the main program). If
the main program has not been flashed properly, the unit reboots again in the bootloader mode to let you
try to upload the new firmware again. If you are having trouble with a system upgrade, please contact
support.
4.3.1 Using bootloader mode
Using a web browser, put the G5 in bootloader mode by pressing the “Switch to bootloader” button in the
"Configuration" webpage (see Figure 2). Then follow the simple screen prompts to perform the required
function.
Figure 10: The bootloader login screen
User name and password will match the ones set up in the main program. Default username and password
are "admin" and “admin”, and are case sensitive.
The next page will offer you to upload a file. After choosing a file and pressing "Upload" let the upload
finish, do not navigate away or refresh the page until you're informed that the upload is complete.

Figure 11: Using the bootloader to update a file
The bootloader can work with three file types. The valid file extensions are:
•.gam – Web UI software update files
•.bin – Firmware update files
•.mem – System settings files that were previously saved through the by using the
“Download” button on the Configuration main screen

GAMATRONIC ELECTRONIC INDUSTRIES LTD.
14 G5 User Guide
4.4 Upgrades
You will not have to upgrade the software unless serious issues are reported and fixed. Your distributor will
contact you if a critical update is required. Never try to upload any *.gam or *.bin files without being
instructed to do so by an authorized distributor or the manufacturer.
Usually, the web user interface file version must exactly match the specific firmware file version, and
therefore you will be asked to upload both .bin and .gam files for an upgrade. Do not change the names of
the files you receive for upgrade. The bootloader will only accept English letters and numbers in the
uploaded file name. The only valid file extensions are “.gam”, “.bin”, and “.mem”.
To perform an upgrade, just choose the relevant file (normally the .bin file goes first) in the upload page and
press the "Upload" button. After you are informed that the upload is finished, choose to upload another file
if required. After all files have been uploaded, press the "Reset" button to return to normal operation.
4.5 Saving system settings
You can save the current system configuration values from the "Configuration" web page by selecting the
“Download configuration” button. The configuration will be downloaded with the name “config.mem” to the
location of your choosing.
You can rename the file if you like, but use only Latin (English) letters and numbers in the file name, and do
not change the .mem extension, otherwise you may have issues uploading it in the boot loader on a later
stage.
When you need to restore the configuration, simply choose the file through the bootloader upload page and
press the "Upload" button. After you are informed that the upload is finished, press the "Reset" button to
return to normal operation.
