The OmniMetrix (OMNI) TrueGuard PRO monitor, with Modbus TCP functionality,
comes with default network configurations, and since it is easy to configure the
network settings on the PowerZone (PZ) control in the field, please configure the PZ
as follows:
The OMNI unit is configured for these network values:
IP Address: 10.0.1.202
Subnet Mask: 255.255.0.0
Gateway: 10.0.1.1
For a single PZ control, set the following:
Modbus Slave ID = 1
IP Address: 10.0.1.101
Subnet Mask: 255.255.0.0
Gateway: 10.0.1.1 (this is not important)
If multiple PZ controls are to be connected, such as in an MPS
configuration, use the following:
MPS Gen #

In the case of a single PowerZone, simply connect the OMNI and PZ via a
CAT5 cable:
In the case of multiple PowerZone controls, connect the system using a
Hub or Switch as shown. This Hub / Switch should be powered by a genset
battery or other uninterruptible power source:

The PowerZone Synch has a display
that is rectangular, horizontally mounted,
and with a nice touchscreen display.
The display will typically be mounted
into a cabinet, as shown here.
The backside of the display, looking from
the inside of the cabinet, is the point of
connection for the OmniMetrix monitor.
The OMNI CAT5 cable goes into the top RJ45
connector, initially labeled “COMPUTER”
Existing Generac CAT5 connection
to the main controller

The OMNI unit may mount onto the shelf
shown inside the cabinet, on the underside
of the top of the cabinet, or on the cabinet
door. The OMNI unit should be mounted so
that the cables cannot drain water down and
into the OMNI unit.
The antenna cable can route out through the
louvers of the cabinet, and the OMNI power
wires (Red and Black) pick up BATTERY+
and DC GND from the customer connection
area at the bottom of the cabinet.
For reference, this is the
PowerZone Synch Control. No
connection from the OmniMetrix
monitor is made to this panel.

The PowerZone Pro looks like the image below. It is somewhat square, and the display is small, consuming only a
fraction of the front face of the control:
There should be a small device
called the “Connectivity Server”,
which allows generator techs to
configure the control wirelessly.
This device, shown to the right, is
also the point of data connection
for the control.

Attach the OMNI power wires, Red and Black, to generator Battery + and –
respectively.
On the bottom side of the Connectivity Server is
an RJ45 connector in the center. Plug the OMNI
CAT5 cable into this RJ45.
