The programming data (DPM and POL setup registers and the user memory) can be preloaded into
DPMs by Power-One or the DPMs can be programmed by the user via the GUI, I
programming interface. The DPMs can be programmed either before or after installation on a host
board.
To modify POL converter settings, the user can directly access the registers of a POL converter via the
I
converted into appropriate SD commands to read / write from / into the registers of a POL converter.
Writing into these registers is limited by the hardware (LCK_N) and/or software write protections. Since
POL converters do not have non-volatile memory, data written directly into POL converter registers will
be lost when the input voltage is removed.

10.4.1 POL Monitoring
Z-One™ POL converters continuously monitor their own performance parameters such as output
voltage, output current, and temperature. The monitored parameters are stored locally in the POL
converters and updated every 1ms. If monitoring feature is enabled, the DPM will be continuously
copying status and parametric data from POL converters into DPM’s monitoring data registers.
The monitoring is enabled by checking the appropriate Retrieve Monitoring bits in the GUI Group
Configuration window shown in Figure 10 or directly via the I
If the status monitoring is enabled, the status of each protection (overcurrent, overvoltage, etc.) is being
reported.
temperature are being reported.
Status and parametric monitoring data of a single POL converter and groups of POL converters can be
examined in the GUI IBS Monitoring Window shown in Figure 11 or directly via the I
specific commands. Status data for each group of POL converters is presented in the Group Status
block in the left top corner of the window. Parametric data for individual POL converters is shown in
Voltage [V], Current [A], and Temp [T] screens.
DPMs also monitor and report programming status of each POL converter and results of CRC
operations.
