This field indicates if the LMU’s log is currently active. An ‘L’ indicates that the log is
currently in use (i.e. one or more records have been stored) where a ‘.’ indicates the log is
inactive.
o
[IP Address]:
This is an optional field if and is only present if the LMU has established a valid data
session. This field will contain the current IP address of the LMU as assigned by the
wireless network. Note that if you see a value of 192.168.0.0, this is an indication that the
LMU has not been able to establish a data session.
o
[<APN>]
The current Access Point Name in use by a GSM LMU.
GPS:
o
[Antenna <Short/Open/Off>]:
This field, if present, indicates a problem with the LMU’s GPS antenna. A value of Short
indicates that the antenna cable has likely been crushed. A value of Open indicates that the
antenna cable is either cut or disconnected. A value of Off indicates that the LMU’ GPS
receiver is off.
o
[No Time Sync]:
If this field is present, it indicates that the LMU’s GPS receiver has not been able to find
even a single GPS satellite. This would likely been seen in conjunction with the above
antenna error, or if the LMU GPS antenna is otherwise blocked.
o
[<FixStatus> <Sat Count>]:
If these fields are present it indicates that the LMU has, or had a valid GPS solution. The
<Sat Count> field indicates how many GPS satellites are currently in use by the LMU. The
<FixStatus> field indicates the type of fix. The Fix Status types are detailed in the LM
Direct Reference Guide.
INP:
o
<input states>:
This field details the current state of each of the LMU’s discreet inputs. This field is always
8 characters long. The left most character represents the state of input 7 where the right
most represents the state of input 0 (i.e. the ignition). A value of 1 indicates the input is
currently in the high state. A value of 0 indicates it is currently in the low state.
o
<vehicle voltage>:
This field will contain the current reading of the LMU’s internal A/D. This will be the
supply voltage provided to the LMU in mV.
MID:
o
<mobile ID>:
This will be the current mobile ID in use by the LMU.
