    903-0628-00 Rev. 1 Model 903-HD User's Guide – FMB-X-2.5 For real-time control systems, average bus loads above 30% are not recommended due to the non-linear increase in latency inherent with contention based protocols. For non-critical applications, average bus loads should be kept below 50% to maintain good performance. LEDs on the AIB-CANBUS card may be used for diagnostics during bench testing.

    903-0628-00 Rev. 1 Model 903-HD User's Guide – FMB-X-2.5 The Model 903 diagnostics software is also helpful during bench testing. Presence of data errors on the program’s display screen may be used instead of the “Link” LEDs to determine the receiver thresholds. This provides a more accurate power budget, since as received power drops, errors occur in the data frames before synchronization is lost.
