TTU-2900 Hardware & Installation Guide - PULS Wiki
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.
o
<mobile ID type>:
This will be the type of Mobile ID in use by the LMU. The available types are, Off, ESN, IMEI, IMSI, USER, MIN and IP
ADDRESS.
INB:
o
<inbound IP address>:
This is the current IP address in use by the LMU. This value should match the IP address of your LM Direct
™
server.
o
<inbound port>:
This is the current UDP port the LMU will use to deliver its LM Direct
™
data. This value should match UDP port you are
using on your LM Direct
™
server. It is typically 20500.
o
<Inbound Protocol (LMD/LMX)>:
This is the current UDP/IP messaging protocol in use by the LMU. In general it should be LMD.
