  • Page 10: Connect Expansion Chassis (Option)

    Use approved ESD precautions, including static-free work area and grounded wrist strap, when handling circuit boards and electronic components. Failure to do so could cause equipment damage due to electrostatic discharge. Only one CSN/Relay card can be used in a ChartScan system. Attempts to install the CSN/Relay card in a slot other than slot #1 of ChartScan’s main unit can cause equipment damage.

  • Page 11: Apply Power To Chartscan

    5. Apply Power to ChartScan ChartScan can be powered from a standard AC outlet. Use the following steps to connect power to your unit. Make sure ChartScan’s power switch is in the “0” (OFF) position. 2. Plug power cord CA-1 into ChartScan’s power connector, located on the rear panel. Plug the other end of the cord into an appropriate receptacle.

    Configuration Aspects for Programmers Configuration Requirements ChartScan does not scan channels on its initial power-up. Even though most user-set configuration states have associated defaults, you must configure a few items before scanning begins. For ChartScan to begin scanning, the controlling computer must perform two operations: (1) Configure each channel, and (2) select the channels that are to be included in the scan.

    Configuration Aspects for Programmers command is used to set these two scan intervals. For example, the following command: I00:00:10.0,00:00:00.1 would set the scan interval to once every 10 seconds and set the post-trigger scan interval to once every 0.1 seconds. As mentioned earlier, the scan interval can be set to run as fast as the current configuration will allow. This is referred to as fast mode.

    Appendix B Pre-Trigger State The Pre-Trigger state is defined as the period after ChartScan has been configured to collect an acquisition (via the Trigger Configuration state, the TRIGGER LED will flash. As in any other acquisition state, the alarms and their associated outputs will be updated at the fastest rate possible under the current channel configuration.
  • Page 201 Configuration Aspects for Programmers To enable this functionality you must perform the following steps: Set the first parameter of the Counts (Y) command to -1. If more than one transition cycle is desired, enable the Auto-Rearm flag of the Trigger Configuration command. If this is done, each transition cycle will be stored in its own Trigger Block within the buffer.

  • Page 202: Post-Trigger State

    Appendix B Post-Trigger State The Post-Trigger state is the period between the occurrence of the trigger event and the occurrence of the stop event. While the unit is in this state the TRIGGER LED will be on and the alarms and their associated outputs will be updated at the post-trigger scan rate.
  • Page 203 Configuration Aspects for Programmers In order for an acquisition to take place, the unit must have a trigger event and can be assigned a Stop Event. This allows different stimuli to begin and end an acquisition. Note: If the trigger start event is level or alarm, at least one pre-trigger scan must be programmed to initiate scanning in order for ChartScan to recognize the event.

The acquisition buffer is a FIFO (First-In First-Out) buffer. In other words, the oldest data to be written into the buffer is the first data to be read from the buffer when a read operation is performed.

  • Page 209: Multiple Trigger Blocks

    Configuration Aspects for Programmers Multiple Trigger Blocks Through the Auto-Rearm capability of ChartScan, it is possible to capture more than one trigger block in the unit’s Acquisition Buffer. Each trigger block would contain one and only one trigger point. These trigger blocks are stacked end-to-end in the buffer; as the last reading of the first trigger block is read by the controller, the next scan to be read will be from the second trigger block.

  • Page 210: Acquisition Buffer Interrogation

    Appendix B Acquisition Buffer Interrogation Note: In the following sections “current trigger block” always refers to the trigger block that is currently being read. The current status of the acquisition buffer may be interrogated at any time by issuing the Buffer Status String (U6) command.
  • Page 211 Configuration Aspects for Programmers 7 - End Scan Pointer This field represents the location in the current trigger block that the end scan occurred. This pointer will always be relative to the trigger point. Since the end scan must always occur after the trigger event this pointer will always be greater than 0.
