Abstract: Systems and methods for pre-warning a monitoring tool for a communication bus are disclosed. In exemplary aspects, a monitoring tool is coupled to a communication bus. The monitoring tool initially monitors the communication bus in a first manner. When a host changes a parameter of signals on the communication bus, the host sends a signal change command. The monitoring device receives the signal change command and changes the manner that the monitoring device uses to monitor the communication bus or the manner that the monitoring device uses to check protocol. By providing the signal change command before the parameter on the communication bus changes, the monitoring device may use a new manner of monitoring the communication bus in a timely fashion such that the monitoring device does not provide erroneous information about the state of the communication bus.
