Module Interfaces
7.6.1.
DisplayPort Interfaces
The MMEXT05 provides two standard DisplayPort/DP++ interfaces for connection to two monitors. The interfaces are
implemented as standard DisplayPort/DP++ connectors, J1 und J2, on the front panel.
7.6.2.
Gigabit Ethernet Interface
The MMEXT05 extension module includes one 10Base-T/100Base-TX/1000Base-T Ethernet port based on one Intel®
i210-IT Gigabit Ethernet controller, which is connected to the x1 PCI Express interfaces of the Chipset. The Wake-on-
LAN feature is supported.
The Gigabit Ethernet interface is implemented as one standard, RJ-45 connector, J5 (GbE) on the front panel.
7.6.3.
USB Interface
The MMEXT05 provides one standard, type A, USB 3.0 connector, J7.
Boards with a USB 3.0 flash drive installed on the front panel USB 3.0 port have been found
to slightly exceed the electromagnetic interference limits. If permanent USB 3.0 type
external storage is required to be connected to the USB 3.0 port, it is recommended to use an
external hard disk drive.
7.6.4.
Serial Port (J8)
One PC-compatible, serial RS-232 port (COM) is available, which is fully compatible with the 16C550 controller. This
port includes a complete set of handshaking and modem control signals. Data transfer rates up to 115.2 kb/s are
supported. The serial port is implemented as an 8-pin RJ-45 connector, J8.
