4.4.3 System Data
System Data screens (see figures 4-6 through 4-16) contain a record of setup information (software
identification and jumper configuration) and real-time sensor data. If you have problems with the SKY497,
verify the configuration screens match the wiring diagrams (see figures 2-2 and 2-3) and have this
information available when contacting BFGoodrich Avionics Systems Field Service Engineering. The field
service engineer must have adequate information to diagnose a problem. System Data screens are accessed
by selecting that option from the Service Menu (i.e., press SELECT with System Data high-lighted).
The System Data screen provides the following choices:
• Software Version
• Configuration
• Data Monitor
