2. Configuring the connection.
In order to configure the connection between the PSU and the PowerSecurity program, choose the
“New Power Supply” option from the “Power Supplies” menu.
The “Configuration of connection” window enables defining necessary parameters of the connection
depending on the type of communication interface.
Caution.
Full procedure of configuring the connection is included in the user manual of individual
interfaces.
Transmission of information about the status of the power supply system is enabled by the use of PULSAR
communications modules for Wi-Fi, Ethernet of RS485 communication. It is also possible to connect the power
supply to the computer via the USB-TTL interface.
