LBI-39224

error/warning triggered outputs are assigned to consoles by use of a console mask.

Type (Device) and Assign (Device)

Each event is assigned to a specific interface module (device) within the CEC/IMC. The Device Type and Assignment fields uniquely identify the Controller Board to which the I/O equipment will be wired. All Controller Boards support Aux I/O except XLTR Controller Boards. Select the device type from the Type drop-down list box; enter the assignment number of the selected device in the Assign text box.

Bit

The Bit field specifies which (Controller Board) input or output bit (0 -

7)is assigned to the event. There are eight input bits and eight output bits per Controller Board. Enter the bit value (0 - 7) in the Bit text box.

Active State

Each I/O event must be assigned an active state − "High" or "Low." An output event will be set to its active state whenever its trigger condition is present. An input event will display its message at the console whenever the specified input transitions to its active state. The high or low state of an I/O event is relative to the actual state of the I/O pin as seen by the Controller Board's processor. This may be inverted from the state of the user equipment connected to the Auxiliary I/O Concentrator Card due to the wiring of the external connections and the buffering circuitry on the Controller Board. See CEC/IMC Digital Audio Switch Installation, Set-Up and Troubleshooting (LBI-38938) for details on the logic characteristics and wiring connections to Controller Board auxiliary I/O ports. Select either High or Low from the Active State drop-down list box.

Event Type

Each event must be defined as either an output event or an input event. Output events change state in response to the specified trigger condition. Input events display a message (up to eight characters in length) at consoles in response to a change in state of the respective input bit. Interlocking group control (Output Interlock), available only with the C3 Maestro for Windows NT console, will allow tying up to eight output events together; acting on one event will also act on the other events in that "interlocked group." As mentioned earlier, this console feature is not available in the first release, and see C3 Maestro for Windows NT Engineering Release Notes (1551-CXC 112 887 Uen) for the console limitations in its first release. See CEC/IMC Digital Audio Switch Installation, Set-Up and Troubleshooting (LBI-38938)
