The T2 card card has a DMB II connector located at the rear of the card, on the opposite side of the I/O bracket. It serves as a maintenance port for developer access to the following ports:

UART to RFSoC
This UART operates at a baud rate configured within the Zynq® UltraScale+™ RFSoC design, and can be used for software debugging of RFSoC PS applications as required.
JTAG to RFSoC
This JTAG chain to the RFSoC can be used for communication with the Vivado® Design Suite during development for programming and debug.
UART to SC
This UART operates at 115 kBd and can be used for querying the SC for system-level information during development.
SWIO to SC
This port can be used to program the SC if the in-band SC firmware update mechanism is not implemented within the RFSoC.
