If the remainder of this section confuses you, don't worry. The SCU in the next section will do all
of the work for you in just a few mouse clicks! The remainder of this section is just to document
what the ESS uses and needs, you may skip to the SCU section.
The ESS comes configured from the factory with a default static IP address of 10.9.9.9 With your
ESS at 10.9.9.9, you will need to assign your network adapter to use 10.9.9.2 or another valid
and unused address in the subnet. We recommend that you keep the 10.9.9.9 IP address
assigned to your ESS, since all of our documentation and videos will use that value. In fact MOST
the user keeps this value assigned to their ESS. However, if there is a need to change it, you may
do so with the Configurator Utility.
Power Supply
The MB3 needs only a single 24Vdc power supply to operate the board. Figure 7, shows power
supply input terminals for 0V and 24V. The 24V, 3A power supply is recommended for general
usage.
There is a non-isolated step-down switching regulator that converts 24V (18-24Vdc) down to 5V
to power most parts of the circuit, including the inputs and outputs.
However, there are also two special isolated DC2DC convertors are used to power the ESS board
and AnaSpeed2, 0-10V analog output.
On board there is also a small fuse for protection against over voltage and polarity reversal.
