3.5.6 Ethernet Interfaces
The 9R1 has two 1000BASE-T Ethernet interfaces at rear connector P4 and two 1000BASE-X interfaces at
connector P6. The Ethernet PHY will auto-select between either P4 or P6.
Both interfaces have a Marvell 88E1512 PHY, connected to the Zynq via RGMII.

3.5.7 Serial COM Ports
There are two serial COM ports connected to PMC connector P4, as shown in Figure
. The
default speed of the COM ports is 115.2k.
COM2 uses RS-232 by default but may be configured for RS-485 operation. Please contact Alpha Data for
further details of the RS-485 mode.
COM0 and COM2 are both connected to PS UART1, and are therefore mutually exclusive due to the PS only
having two UART interfaces.
