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
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.
