Chapter 5 Troubleshooting Note: The SM could receive messages not intended for it. In this case, the SM discards the messages and stays in this state. This state indicates that the headend controller is not receiving data and is not registering the SM.
Status Monitor Troubleshooting Error State If the SM is in the "Error" state, then the transponder core module in the SM is defective. Replace the transponder core module or the entire SM as necessary. WARNING: Be sure that the LCM software and transponder core module software match. Software versions prior to 3.00.03 are not compatible with software versions 3.00.03 and above.
