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. Connect an Ethernet cable to the RJ45 connector marked LAN on the front panel.
2. 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, GMAC-5 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 GMAC-5 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 GMAC-5 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 GMAC-5 on your computer network by running the Discover.NET software, which is
compatible with Windows XP and later Windows releases. Discover.NET can be downloaded from
“http://www.gamatronic.com/gmac-5.html”. 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 2: The main web interface screen
See chapter 5 for further details on the software configuration process.

GMAC 5 User Guide 5
3. USER INTERFACE
The User Interface (UI) is built for quick and intuitive access. The usual page structure is:
Figure 3: Layout of the user interface screen
1. Company logo, name, and the current firmware version, required for support purposes.
2. UPS, volt-free contacts, environment, and other system indicators showing current status.
3. Language selector, functional on all pages. Language setting is saved with a "cookie" in your browser.
4. Navigation tree lets you efficiently switch between various informational and configuration pages.
Items in navigation tree can vary depending on system configuration.
5. All data related to the current informational or configuration page is shown in the middle of the screen.
6. Messages about system-wide conditions may be displayed in the status bar.
3.1 Dynamic updates
The web pages are dynamically updated every 3 seconds. This auto-refresh process stops after 5 minutes
so as not to create unnecessary network traffic, and a message will be shown in status bar (item 6 in Figure
2). 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 irrelevant.
To restore the dynamically updated connection, just refresh the page in your browser.

3.2 Main screen
After typing in the unit's IP address in the web browser, you will see the main screen that shows general
system condition and basic information about all features that have been enabled.
Figure 4: The main web interface screen

GAMATRONIC ELECTRONIC INDUSTRIES LTD.
GMAC 5 User Guide 7
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 GMAC-5’s rear panel,
and configuring the connection in GMAC-5, 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.

3.2.2 Log
The log menu shows you the total amount of events saved in the log, and will offer to either download the
log to your computer (as a csv file) or clear it. Some systems, like Power+ modular UPS units, have their
own internal log, and in such cases the log screen will enable you download that internal log as well.
3.2.3 Configuration
The configuration menu functions are described in detail in chapter 5.

GAMATRONIC ELECTRONIC INDUSTRIES LTD.
GMAC 5 User Guide 9
4. ADDITIONAL FEATURES
4.1 Automated shutdown of computers
If a UPS is being monitored by GMAC-5, and that UPS is providing power to computers, you can instruct
GMAC-5 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 5.6), or can be obtained from your GMAC-5 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.
4.2 The bootloader
Bootloader mode is used to upgrade GMAC-5’s system software, and to upload a previously saved
GMAC-5 configuration.
There are two ways to put GMAC-5 into bootloader mode:
•Use the “Switch to bootloader” button in the Configuration screen on the web interface (Figure 8);
Figure 8: Bootloader mode button
OR
•Reset (or power on) the device while pressing the “Act” button.
In bootloader mode GMAC-5 takes its IP address according to the user’s instruction in the
“Actual IP address” field in the “Configuration > Network” screen (see section 5.1 “Network configuration”).
When GMAC 5 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), and do not perform any activity for 5 minutes, the device automatically restarts in normal
operation mode.
If the GMAC-5 unit always boots in to the bootloader, this means that the main software is corrupt. You
must update the software again.

GAMATRONIC ELECTRONIC INDUSTRIES LTD.
10 G5 User Guide
4.2.1 Using bootloader mode
Using a web browser, put the GMAC-5 in bootloader mode by pressing the “Switch to bootloader” button in
the "Configuration" webpage (see Figure 8). Then follow the simple screen prompts to perform the
required function.
Figure 9: 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 10: 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.
GMAC 5 User Guide 11
4.2.2 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 unless 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.
4.2.3 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.

5. CONFIGURATION
All system configurations are performed under the configuration menu. Use this menu to update basic
system settings like identification names, and to quickly enable or disable system functions without
removing the functions from the current configuration.
The Identification information entered on this screen (Unit name, Site, Manager) appears on the main
screen upon entry into the system. This is to enable you to distinguish between units in the event that you
are operating multiple GMAC-5 units.
Figure 11: Configuration menu expanded
There are also three buttons near the top of the screen:
•DOWNLOAD CONFIGURATION:downloads to your computer a configuration file that can be kept for
future uploading through the bootloader to restore system configuration to the same state. The
restore works only if the system is of the same software version as was in effect at the time the
configuration backup file was created (unless otherwise mentioned in the documentation for the
new software release).
•RESTORE TO FACTORY DEFAULTS:returns GMAC-5’s configuration to default factory settings
excluding password. To restore the factory default user name and password (admin/admin) see
section 1.5.2.
•SWITCH TO BOOTLOADER: causes GMAC-5 to reboot in bootloader mode. You must refresh the page
manually to see the bootloader web interface. It is possible that when switching to bootloader mode
the device will receive a different IP address. In bootloader mode GMAC-5 takes its IP address as
per the user’s instruction in the “Actual IP address” field in the “Configuration > Network” screen
(see section 5.1 “Network configuration”).

GAMATRONIC ELECTRONIC INDUSTRIES LTD.
GMAC 5 User Guide 13
5.1 Network configuration
Use the “Network” configuration function to specify the details of your connection to the local Ethernet
network.
Under "Static IP address" specify the connection details to be used by GMAC-5 when no DHCP address is
available, or when you specify that the static address is to be used at all times.
Under "Actual IP address" select the desired mode of operation, which can be one of the following:
•Static IP
•DHCP, fallback to static IP
•Device IP, fallback to DHCP
•Device IP, fallback to static IP.
In the operation modes listed above:
•Static IP is the IP address defined under "Static IP address",
•DHCP is the IP address received from DHCP server automatically, and
•Device IP is the IP address received from the controller of connected power system (if supported
by protocol), such as the Power+ UPS or the 1UDC+ Power System.

14 G5 User Guide
5.2 Date/Time configuration
Use the “Date/Time” menu option to set GMAC-5’s internal calendar and clock.
Enter the current time and date, or click on "Get local time" button to update all fields with the current local
time from your PC. The update does not take effect until the “Apply” button is selected.
The date and time is used to timestamp entries in the event log.
If you choose to receive network time updates, the device will try to receive NTP time from the server
(defined in the Network configuration) every three hours. Pay careful attention to the time zone and DST
settings when using network time, since these parameters will not be updated automatically.
"Set current time from SNTP server" will simply try to access the server immediately and return a reply.
This will also instantly update system time upon successful reply.

GMAC 5 User Guide 15
5.3 Configure a serial connection
The “Serial” function is used to describe GMAC-5’s communication link with a UPS or other power system.
Select the protocol and additional serial communication settings. Use the GMAC-5 compatibility table
(Table 6) to find out what protocol is supported by your device.
If you are not sure of the particulars of the connection, use the "Detect" button, which will “talk to” the power
system to determine what protocol it supports. The speed of the power system’s response to the Detect
function can vary. Watch the screen for messages from the auto-detection process. If the Detect function
succeeds, all of the fields in the screen are automatically updated with required values – there is no need to
click "Apply" after detection, detected values (or "Disabled" if nothing was detected) will be saved
automatically.
