SV3-1167408762 “SV3-029” Version:1.1.3

AIS baud rate:
config.devices.ais:serial {serialPort=LX4, baudRate=38400, mode=rs232}

%ais.getDeviceSerialParameters()
default for AIS baud rate is 115200, some older CCUs/AIS receivers will be set to 38400.

%ais.changeBaudRate(<baud_rate>)

Also there is an issue with 3.2.2 upgrade and make sure that:
%config.readPath("devices.iridiumModem.useMSSTMandSBDLOE") should = false, if true issue this command:

%config.writePath("devices.iridiumModem.useMSSTMandSBDLOE",false)
