Board Location Guide
This board location guide is provided to help you install the DVCPRO boards in a
PDR 200 Video File Server that is not an Option DV, that is, not shipped from the
factory as DVCPRO ready. The board layout for an Option DV PDR 200 eases
DVCPRO board installation, but other systems may require that you move
existing boards to accommodate the DVCPRO boards. This guide will help you
do that.
If you move any circuit boards, remember that some boards must occupy specific
slots, while others can be installed in almost any slot as long as their I/O
requirements are met (see Table 10 on page 57). The board location guide
identifies the video router inputs and outputs of each Profile board currently
available, as well as the input and output connections on the video router
connectors on the motherboard.
This guide provides a general approach to board location. It explains the
relationship between the motherboard and video router connectors and provides
tables, charts and examples to assist you in installing boards.
Video Router to Motherboard Relationship
The video router provides and controls video data to twelve connectors on the
motherboard. These video data connectors are aligned with the main motherboard
connectors for slots J5 through J16. Since the Reference Genlock (Ref Gen) board
must occupy J16 to provide the necessary system clocks, this discussion excludes
J16.
When choosing a slot for a board, the major constraint for a slot is how the board
connects to the video router. Not all boards require the same number of video I/O
connections, and not all video data connectors provide the same number of video
I/O connections. Therefore, you must know how many input and output
connections the board needs, if any, and the slots available that meet those needs.
Table 10 on page 57 lists each of the boards which may be installed in the Profile
system and the recommended slots, possible alternatives, and restrictions for each
board. If more than one slot is recommended or possible for a board, those slots
are listed in the order of preference.
