User Manual LineTroll R400D
Response to sender
When this function is enabled, the LT-R400D will send a response message back to a
sender of a command or configuration setting regardless whether the sender is
programmed as one of the recipients or not. If disabled, the responses will only be
sent to the recipients.
The messages sent to the device must be in accordance with the correct message
format to generate a response. E.g. advertising messages sent from the network
provider will not generate any response.
Alarm trigger
When setting this function to ‘1’, the device will send both the alarm message and the
reset message of the same message. Set to ‘0’, the device sends only the active
alarms and not when the same alarm is deactivated.
Limiting the number of SMS per 24h
The number of SMS’ the device can send in a 24 hour period can be set between 10
and 3000.
Passwords
All messages sent to the device must contain a password corresponding to the
programmed password.
It is also a separate configuration password which will lock all configuration settings
(trip-levels and other important functionality settings) to avoid these being
manipulated. It is still possible to request status etc using the main password.
GPS
The LineTroll R400D is equipped with a built-in GPS which is used to read the position and to
synchronize the on-board real-time clock.
The GPS can be activated in a configurable interval (default every 24hour) and will
synchronize the time as well as reading the position every time it is switched on (reset or
sync).
All alarms and status requests will be time-stamped with an accuracy of 100ms.
If the synchronization fails due to no contact with the satellites, the messages from the device
will be logged with the time from the PC clock.
The GPS position can be read from NetTroll FDP configuration utility and will return the
position (longitude, latitude) in decimal degrees.
