Monitoring Voltage and Current
Voltage and current monitoring and control for the Maxim power system is available through
either the ZCU1285 System Controller or via the Maxim PowerTool software GUI.
The ZCU1285 System Controller is the simplest and most convenient way to monitor the voltage
and current values for the power rails listed in
how to use this built-in feature, see
The ZCU1285 board includes these PMBus connectors:
• J21 (callout 32,
PMBus interface dongle (Maxim part number MAXPOWERTOOL002) and the
PowerTool
GUI.
• J4 and J145 (callout 11,
serial transceiver power module's PMBus. The pinouts for J4 and J145 are shown in the
following figure
• J25 (callout 39,
module PMBus. The pinout for J25 is shown in the following figure.

The onboard Maxim power controllers by default are isolated from the serial transceiver power
module's PMBus. However, the two interfaces can be linked by removing the shunt on J8 or J154
(serial transceiver PMBus isolation). This configuration is required when using Maxim PowerTool
to monitor and control both the RFSoC power rails and the serial transceiver power rails using
the Maxim InTune Digital PowerTool GUI.
