LMU-4200™ Hardware and Installation Guide
o [./L]:
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.
For example you may see this if the vehicle is in a garage when the LMU is powered up.
