HARDWARE CONNECTIONS
The I/O configuration allows creating several different connections between the recorder and the external devices.
See the example figures below.
Figure 60. Hardware Connection 1
In this example, all of the recorders send and receive events from one main recorder (Recorder #1) that is the interface
between the DX9000 and the external devices.
Figure 61. Hardware Connection 2
In this example, each recorder sends and receives events from its own external devices.
Figure 62. Hardware Connection 3
In this example, the entire system sends ASCII codes to the CM9760 matrix via the CM9760-DT.
