Inserting Telemetry
All telemetry messages sent from telematic units to the Manifold will be of the following format:
<tmu type>,<id>,<message type>,<time stamp>,{message-specific parameters}[,{name/value pairs}]<CR><LF>
| Attribute name | Value(s) | | tmu type | Type of device which sent this message:
eg. raptor, opticon, halo, ibright | | id | The id of the TMU:
eg. 104489 or 0110130001525004%2F3 where the id is 0110130001525004/3 | | message type | Can be of one of the following values:
- beacon
- ignition
- antenna
- trailer_connection | | time stamp | Time stamp of when the message was sent, in ISO8601 format:
eg. 2008-06-04T03:27:59Z | | Supplementary name/value pairs (optional) | An HTML form-encoded string holding other undefined parameters for the message:
eg. temperature=15&name=fred&trailers=plc_12%2Cplc_34
TRAILERS
If the supplementary name/value pair list includes trailers, then the value is considered a comma-separated list of trailer ids. Naturally, the commas must be encoded as %2C.
Each trailer provided will receive the same telemetry message as their master.

Note: The ID attribute and all message-specific values must be URL-Encoded Message Type: Positional Beacon [beacon]
A positional beacon.
| Attribute name | Value(s) | | latitude | The latitude in decimal degrees (WGS84 coordinate system):
eg. -39.49115 | | longitude | The longitude in decimal degrees (WGS84 coordinate system): eg. 176.88822 | speed
| Speed in km/h at which the vehicle is driving at: eg. 73 | | heading | GPS heading degrees true: eg. 141 | | horizontal dilution of precision | Value between 0.8 (good satellite geometry) and 10 (poor satellite geometry). Vigilo filters values > 10:
eg. 1.2
| | number of satellites | Number of GPS satellites used in GPS position fix:
eg. 9 | | beacon sequence number | 1 |
Message Type: Ignition [ignition]This message communicates the current status of the ignition of an asset. It does not necessarily imply a change in the status of the ignition.
| Attribute name | Value(s) | | ignition state | ON or OFF - Specifies whether the vehicle ignition is currently on or off |
