Connect a USB A to Micro-B USB cable from the host PC to the ZCU1285 USB/UART connector
(callout 5, Figure 1-2). In the SCUI click File → Change the System Controller Port. In the Select
the system controller port window, select the COM port associated with Silicon Labs Quad
CP210x USB to UART Bridge: Interface 2, and press OK. The SCUI is now connected to the
ZCU1285 board.
IMPORTANT! Make sure J121 is set to position (2-3) DUT PMBUS DIS to isolate the DUT PMBUS/I2C signals
and prevent bus contention. If contention occurs, the system controller cannot execute commands.

or the SuperClock-RF2 Module (CLK-103).
CLK-101 Tab
This section includes a description of the CLK-101 tab options that are used to control the
SuperClock-2 Module. Arbitrary field value entries are used to illustrate the operations. The
