PSC SystemThe "Device" column lists the devices that should be connected to the CAN bus for the current configuration.The "Status" column indicates "Connected" if the device is detected. The "Status" column indicates "Not Found" if the device is not detected. The "Status" column may indicate the minimum required application firmware version for a device if the current application firmware version is too old.The "Status" column may indicate the minimum required loader firmware version for a device if the current loader firmware version is too old. If both the loader firmware version and the application firmware version are too old, the "Status" column indicates loader firmware version as the priority.The "App." column indicates the current detected application firmware version for the device. If the device is not detected, the "App." column is left blank.The "Loader" column indicates the current detected loader firmware version for the device. If the device is not detected, the "Loader" column is left blank. If the loader firmware version is not reported for a device the "Loader" column is left blank.The "Diagnostics" device display screen content will vary. The content of the "Diagnostics" device display screen will depend on the type of machine that the AccuGrade system is installed upon. However, for Hex applications, the "Diagnostics" screen content may contain all or a portion of the following devices:
CD700
MS990C – Left
MS990C – Right
AS21 - Pitch
