10.1.5 User Memory
This non-volatile memory block is reserved for users’ notes and not related to other functions in the
DPM. It can be used to save user-specific information such as manufacturing data and location, serial
number, application code, configuration file version, warranty or repair information, etc. A total of 1024
Bytes organized in 4 pages is provided. The user memory can be accessed via the GUI System
Configuration window shown in Figure 9 or directly via the I
the user memory can be saved into the configuration file by clicking OK in the User Memory window
shown in Figure 6.
10.2
The ZM7300 DPM includes all necessary circuitry to control and monitor four Auxiliary Devices.
Virtually any device which has an on/off input and a monitoring output can be an Auxiliary Device.
Typical examples of Auxiliary Devices include analog POL converters, linear regulators, and fans.
Auxiliary Devices are controlled and monitored via the Graphical User Interface.
The DPM treats Auxiliary Devices as Z-One™ POL converters: each Auxiliary Device has an address
and is assigned to one of the groups as shown in Figure 9 (device at addresses 03). Turn-on and off
delays can be programmed, and faults can be propagated from POL converters to the devices.
Auxiliary Devices are controlled through standard group turn-on and off commands and are fully
synchronized with turn-on/off timing of POL converters.
