    3. Press the Take Key. All the illuminated keys turn off. Input 1 is disconnected from all the outputs on both levels. If all the illuminated keys on the panel do not turn off, or if the Cancel Key flashes, the command was not successful. Press the Cancel Key to clear. Regardless of the system response, execute the test switch.
  • Page 44 Executing Switches Executing Switches When executing a switch with one output, either the Input Key or the Output Key may be selected first. To route an input to multiple outputs, the Input Key must be selected before the Output Key. This example routes Input 2 to Output 1 on both levels.
  • Page 45 Select the outputs that you want to disconnect and then press the Take Key. Any output keys that remain illuminated are still connected. To disconnect a single switch: (Input 4 is routed to Output 1 on the Video Level) 1. Press the Video Level Key. The Video Level Key is the only key illuminated.

  • Page 46: Verifying Signal Status

    Verifying Signal Status Verifying Signal Status You can verify signal status to confirm that a switch has executed correctly, or that multiple outputs are correctly routed. An output can only receive a signal from one input; so verifying the status of an output will only illuminate the key of its one current input.

  • Page 49: Chapter 7 - Bcs Serial Control Protocol

    BCS Serial Control Protocol AutoPatch has developed a command language, BCS (Basic Control Structure), for operating the system through an external device and for diagnosing problems. The Precis uses a subset of this language for switching, disconnecting, and verifying status of commands. BCS command lines are entered into a terminal emulation program (e.g., Windows HyperTerminal) from an external control device which sends commands to the system.

  • Page 51: Generating Commands (Execute, Disconnect, Status)

    Command lines begin with the applicable command character, followed by the characters and numbers indicating levels, inputs, and outputs. Command lines must always end with “T” (Take) command, which tells the system to execute the command. Example of a command line: CL1I2O3T (C)Change on(L1) Level 1,(I2)Input 2 to(O3) Output 3, (T) Take to execute the command.

  • Page 52: Disconnect Commands

    Generating Commands (Execute, Disconnect, Status) Example: CI2O3T Change on both levels, (I2O3) Input 2 to Output 3, (T) Take to execute the command. Disconnect Commands Disconnect command lines begin with “D” and specify an input or output, followed by the Take command. Example: DL2O3T (DL2) Disconnect on Level 2, (O3) Output 3, (T)Take to execute the command.

  • Page 53: Command Line Responses

    Command Line Responses Command characters and numbers appear on the screen when the system accepts them. A command line has successfully executed when the entered “T” command appears. If a command or number is not accepted, a different character appears and the command is not executed.
  • Page 54 Executing a Test Switch All command characters appear when accepted by the system. When a command is successfully executed, all of the characters appear as entered. If a command character or a number is not accepted, a different character appears indicating that the command did not execute.
