Problems: 1. Wrong parameter setting (regional code, master station IP Address, communication port,APN, stipulation type, Baud rate). 2.Abnormal master station parameter(channel group mess). 3.Concentrator fault

Solution steps:1.Check whether the concentrator parameters are set correctly. Reset the concentrator parameters if they are wrong. 2.Check the main channel group of off-line concentrator in On-site Debugging---File Parameters. Synchronize from SG186 may result in loss of main channel group parameters and terminal off-line.3.If the concentrator is still off-line when communication parameters are correct, the concentrator may breakdown and terminals need to be replaced.
