Chapter 3: Installation and Operation
Data from the Daughter Card will be sent into xPortA and/or xPortB and will be transferred through the link. The data stream
would look similar to the image below.
Figure 3-6. Data Stream packet structure. 20 total data allocations: 14 are used for the DVI video signal, 2 are used for the USB
HID data, and the last 4 data allocations are used for the xPortA and xPortB Daughter Cards.
NOTE: If the Tx and Rx modules connected to xPortA and xPortB are matching, the additional peripheral signals will be
transmitted; if not, the Rx will not output any of the optional signals but the base module data will always match because
of that!
3.4.3 Power Connections
Most Interface Cards and some Daughter Cards will have a power interface located on the card. They can be easily found by
looking for the 1- or 2-position brown header located on the board (see the image below).
Figure 3-7. Showing the power connections on the card.
You can remove the cover of the 2-, 4- or 6-Port chassis to access the power connections. You will connect the power
connections from the 2-, 4- and 6-Port chassis to these power connections on the cards. Each chassis will have the power
connections already included that are connected to the power supply. You should find at least one power connection on the
2-Port chassis, at least two power connections on the 4-Port chassis, and at least three power connections on the 6-Port chassis.
You will need to use the Power Jumper Cables to supply more power connections in order to power more cards in certain
applications.
