distinguish which unit is reporting. If the Vehicle ID is included, it is delimited with a

semicolon.

;ID=AAAA

The default setting is: ID set to “0000”

To include the vehicle ID in a TAIP sentence, you would use the TAIP Enables parameter

(2048). Bit 1 controls the presence of the Vehicle ID. If this bit is set, then the ID is

included. If it is cleared, it is omitted.

The Vehicle ID is controlled by Parameter 2050. Each of the four indices of this parameter

map to a single ASCII character of the ID string. Index 3 maps to the least significant digit

and index 0 maps to the most significant digit. The value should be the decimal

representation of the desired character. Valid values range from 48 to 57

As an example, to include a vehicle ID value of 9450 with each TAIP sentence you would

use the following five commands:

Set the LMU to include the TAIP Vehicle ID:

AT$APP PARAM 2048,0,2,2

Configure the vehicle ID:

AT$APP PARAM 2050,0,57

AT$APP PARAM 2050,1,52

AT$APP PARAM 2050,2,53

AT$APP PARAM 2050,3,48

12.1.5.2 Event Code

TAIP sentence may include an optional Event Code. This is generally used when TAIP

messages are generate by means of a PEG script as opposed to querying or scheduled

reporting.

The extension’s format is as follows:

EV=XXX

The event code may range from 0 to 149 or 255. A value of 255 is used to indicate that the

TAIP sentence was generated by a Real-Time PEG Action, a query request or a scheduled

report. Only a PEG script generated message will contain Event Codes 0-149.

To include the Event Code with a TAIP sentence, you would use bit 6 of the TAIP Enables

Parameter. If this bit is set, the Event Code is included, if it is cleared, the Event Code is

omitted. To include the event code you would use the command:

AT$APP PARAM 2048,0,64,64
