Application Example

The 972 responds to commands received from the Access System, or it can respond to Product Select Buttons connected directly to the 972 PSB ports. When the 972 receives a switching command from the Access Bus, it translates the number of the product that is to be selected into appropriate RS-232 commands that can be sent to as many as 16 switches in the HDMI selection tree, allowing the desired HDMI source output to be routed downstream to the rest of the demonstration system.

The 972 operates in either Master or Slave Mode. In Master Mode, the 972 behaves like other Access electronics modules and is addressed in the same way as an Access source module except for the special Module ID addressing (see the HDMI address tree on page 6). The address scheme must accommodate the tree structure required for HDMI switches. Module ID addressing is explained in detail below.

In Slave mode, the 972 mirrors the switching activity of an Access electronics module, such as a 922, 954 or 947. The 972 in Slave mode is not directly connected to the EXPANSION port as other Access expanders are, but must be addressed identically to the “master” Access module so that it can receive commands from it through the System Bus. See page 3 and page 7 (Figure 10) for more on Slave mode.
