Monitoring Voltage and Current
Voltage and current monitoring and control for Maxim power system is available through
either the VCU1287 board system controller or the MaximPower Tool software GUI. The
VCU1287 board system controller is the most convenient way to monitor the voltage and
current values for the power rails listed in
Table 3-2
. For details on how to use this built-in
feature, see
Power Monitoring Data Menu
in
Appendix D, System Controller
.
The VCU1287 board includes these PMBus connectors:
• J21 (callout 20, Figure 1-2), for use with the Maxim USB-to-PMBus interface dongle
(MAXPOWERTOOL002
[Ref 5]
) and the InTune Digital Power GUI.
• J4 (callout 21, Figure 1-2) is used to connect to the MGT power module PMBus using
the Maxim USB-to-PMBus interface dongle (MAXPOWERTOOL002
[Ref 5]
) and the
InTune Digital Power GUI.
Note:
Use wires to connect the J4 pins to the Maxim MAXPOWERTOOL002 dongle as shown in
Figure 3-2
.
