1.5.2 Restore GMAC5 factory settings
If desired, you can clear GMAC5’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”.
1.5.3 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 20).
Figure 3: 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 GMAC5 receives its IP address from DHCP server. If no address is received, GMAC5
uses the default IP address: 192.168.0.198.
When GMAC5 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 GMAC5 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. 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, GMAC5 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 GMAC5 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 GMAC5 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 GMAC5 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/GMAC5.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 4: The main web interface screen
See chapter 5 for further important details on the software configuration process.

3. User interface
The User Interface (UI) is built for quick and intuitive access. The usual page structure is:
Figure 5: Layout of the user interface screen
1. Company logo, name, and the current firmware version, required for support
purposes.
2. UPS, 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
of no mouse activity so as not to create unnecessary network traffic, and a message will be shown in status
bar (item 6 in Figure 4). 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 obsolete.
To restore the dynamically updated connection, just refresh the page in your browser.

3.2.1 Monitoring a UPS or a 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 GMAC5’s rear panel,
and configuring the connection in GMAC5, using the “Serial” option in the “Configuration” menu.
3.2.1.1 UPS MONITORING
When UPS monitoring is enabled as described in section 13.2.1 above, and the “UPS” menu option is
selected, the UPS’s status and other general information is displayed. 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.
