"Satellite Information" screen (PL121SR and PL321SR)Note: Disregard the value of the "Average Wireless Communication Error Count" when satellite communication status value equals "Not Established". An "Average Wireless Communication Error Count" message is normal if communication with the satellite is not established.

Satellite Communications Status Information    
Communications Status Information    System    Description    Notes    
Satellite Communication Status     PL121SR and PL321SR     Established: The PLM has an active connection to a satellite.        
Not Established: The PLM does not have an active connection to a satellite. The message, "Not Established" is not an error mode. Satellites move quickly. Often times a satellite has moved out of view of the antenna and another has not yet moved into view of the antenna.
Satellite Network Control Center Communication Status     PL121SR and PL321SR     Established: The satellite that the PLM is communicating with has a connection to a Network Control Center (ground station).        
Not Established: The satellite that the PLM is communicating with does not have a connection to a Network Control Center (ground station). The message, "Not Established" is not an error mode. Satellites move quickly. Often times a satellite has moved out of view of the antenna and another has not yet moved into view of the antenna.
Average Wireless Communication Error Count     PL121SR and PL321SR     This value is an indication of the quality of the connection with the satellite used for troubleshooting satellite connections. The lower the number, with a minimum of zero, the better the signal strength. As the value increases, the amount of transmit time for signals increases.        
Communications Satellite Identification Number     PL121SR and PL321SR     This value identifies the particular communications satellite that the PLM is tracking.     If no satellite is in range, the indication will be "Conditions not met".    
Communications Modem Signal to Noise Ratio     PL121SR and PL321SR     This value indicates quality of the communications signal expressed as a number. The higher the number, the better the signal.     A value below 10 will typically cause no transmissions. The higher the value above 10, the better the chances of successful message transmission.    
Communications Modem Signal Quality     PL121SR and PL321SR     This value indicates the overall quality of the communications signal based on several factors expressed as a percentage.     0% = poor quality
100% = best quality    
Communications Modem Status     PL121SR and PL321SR     This value indicates the provisioning status of the communications modem.     Normal status is enabled. If status is "Disabled" or "Pending", contact your Caterpillar Technical Communicator.    
Communications Modem Activation Delay Time     PL121SR and PL321SR     This value indicates the time that the communications modem has remaining in a "pending" status.     Displayed in h/m/s format.
