Serial Digital I/O Upgrade Installation

Board Location Guide

This board location guide is provided to help you install a serial digital I/O board
in a PDR200 or PDR100. The 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. Use this
information when:

• Adding a board to the Profile system and selecting a slot into which you can

install it.

• Moving boards to meet requirements for new boards.

As you move boards, remember that some circuit 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 1).

From the factory, a single, two-channel serial digital I/O board comes installed in
slot J14 in a PDR202D. The recommended slot for the additional serial digital I/O
is slot J15, although it could be installed in any available slot from J5 to J15. In
order to use embedded audio, however, the serial digital I/O boards must be close
enough to the Audio Signal Processing Board (ASPB) for the audio clock and
Sharcnet cables to reach. Also, the board must not be in a slot with shared inputs
when all the inputs are taken by the adjacent board, such as the four-channel
analog output board or the analog composite monitor board.

This section provides a general, simple 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 this and other 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 meets those needs.
