The NetGuardian LPG Controller
Meet the NetGuardian LPG Controller
The NetGuardian LPG Controller is ideal for remotely managing up to 4 liquid propane tanks. The LPG
Controller analyzes the propane flow from each tank to achieve a balanced consumption of propane
from all tanks assigned to the automation process. The unit also has an override feature, so that a tech
can manually turn on and off valves through the web browser interface. The NetGuardian LPG Controller
has an indicator LED for each tank showing valve status (open/close) and for trigger points for tank
level.

The Back Panel of the NetGuardian LPG Controller
Power Connection6.1
The NetGuardian LPG Controller uses a single power input, powered through one barrier plug power connector.
NetGuardian LPG Controller Power Terminals and Fuses
To connect the NetGuardian LPG Controller to a power supply:
1. Locate the metal grounding lug next to the symbol . Use the grounding lug to connect the unit to earth ground.
2. Insert the eyelet of the earth ground cable between the two nuts on the grounding lug (Ground cable not included).
3. Choose a barrier plug power connector to attach your power cable to. One plug is used for main power and the
other is used for backup power. Both plugs are interchangeable so it does not matter which plug you select. Each
plug's right terminal is Ground and its left terminal is Battery Lead.
4. Insert a battery ground into the power connector plug's right terminal (GND) and tighten the screw.
5. Insert a battery lead to the plug's left terminal and tighten its screw.
6. Insert fuse into the fuse distribution panel.
7. Check the power status LED for polarity.
8. Measure voltage. Connect the black cable onto the ground connector of your Digital Voltage Meter (DVM) and red
cable onto the other connector of your DVM. The voltmeter should read between the values listed on the silk
screen next to the power connector.
9. Insert the local fuse into the power fuse slot. The power plug can be inserted into the power connector only one
way to ensure the correct polarity.
Note: The negative voltage terminal is on the left and the GND terminal is on the right.
10.Verify that the LED is lit. To confirm that power is correctly connected, the front panel status LED will flash
RED and GREEN, indicating that the firmware is booting up.

Quick Start: How to Connect to the NetGuardian LPG
Controller
7
Most NetGuardian LPG Controller users find it easiest to give the unit an IP address, subnet and gateway through
the front craft port (TTY interface) to start. Once these settings are saved and you reboot the unit, you can access it
over LAN to do the rest of your databasing via the Web Browser interface.
Alternative option: You can skip the TTY interface by using a LAN crossover cable directly from your PC to the
NetGuardian LPG Controller and access its Web Browser.
...via Craft Port (using TTY Interface)7.1
NetGuardian LPG Controller Craft Port
Use the front panel craft port to connect the NetGuardian LPG Controller ITto a PC for onsite unit configuration.
To
use the craft port, connect the included DB9 download cable from your PC's COM port to the craft port.
Note: The following images display the setup process done in Windows XP.
The following steps will occur the first time any DPS USB equipment is used on this PC. If you've used a
different DPS USB device before and have installed the DPS USB drivers, then skip to Step 9.
When you first connect the NetGuardian LPG Controller to your PC via USB, a "Found New Hardware" message
will appear:
1. Click the "Found New Hardware" message/icon to launch the "Found New Hardware Wizard".

12
2. Select "Install from a list or specific location (Advanced)"
3. Click "Next >"
4. Select "Search for the best driver in these locations."
5. Insert NetGuardian LPG Controller Resource Disc (CD) into your PC.
6. Click "Browse"

13
7. Select the "Driver" folder of your NetGuardian LPG Controller Resource Disc Disc (CD) and click "OK"
The following message will confirm installation of a new "USB Communications Port"
8. Click "Finish" to close the Wizard.
Now that the driver has been installed, a new COM port is being emulated on your PC. Before using
hyperterminal, you must confirm the identity of that new COM port (COM1, COM2, COM3...) in the Windows
Device Manager.

14
9. Right-click the "My Computer" icon on your desktop, then click "Manage"
10.Click "Device Manager" in the left pane.

15
11.Expand the "Ports (COM & LPT)" section in the right pane. Look for "USB Communications Port (COMx)".
Note the number of the COM port ("COM3" in the example above).
12.Click on the Start menu > select Programs > Accessories > Communications > HyperTerminal.
13. At the Connection Description screen, enter a name
for this connection. You may also select an icon. The
name and icon do not affect your ability to connect to
the unit.
14. At the Connect To screen, use the drop-down
menu to select the COM port you found earlier in the
Device Manager.

16
15. Select the following COM port options:
• Bits per second: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
Once connected, you will see a blank, white
HyperTerminal screen. Press Enter to activate the
configuration menu.
16. When prompted, enter the default user name
admin and password dpstelecom. NOTE: If you
don't receive a prompt for your user name and
password, check the Com port you are using on your
PC and make sure you are using the cable provided.
Additional cables can be ordered from DPS Telecom.
17. The NetGuardian LPG Controller's main menu will
appear. Type C for C)onfig, then E for E)thernet.
Configure the unit's IP address, subnet mask, and
default gateway.
18. ESC to the main menu. When asked if you'd like
to save your changes, type Y for Y)es. Reboot the
NetGuardian LPG Controller to save its new
configuration.
Now you're ready to do the rest of your configuration via LAN. Please refer to the next section "...via LAN" for
instructions on setting up your LAN connection.
