mTrak vehicle tracking system | Preferences

Preferences

The way that the mTrak units operate can be configured with at text message.
The syntax is:-

Prefs [unit select],[settings], [currency symbol],[name],

[unit select]
This is "k" to indicate that texts should be in km or km/h or blank for miles and mph

[settings] In this section the following functions are turned on

  • "N" If this is included, the phone and the GPS receiver in the unit will stay on all the time.
  • "V" Voltage. If this is included, the supply voltage (and backup voltage on mTrak Plus) will be included in texts
  • "S" Signal. If this is included, the mobile network signal level will be included on texts
  • "I" Ignition sense. This is for mTrak plus units use voltage for ignition status, the way that the mTrak basic units always do.
  • "C" Permanent charging. This is to get the internal battery to charge whenever there is a power supply connected.
  • "P" Positive ground. This is to get the ignition input to work the opposite way, so a voltage nearer to the negative supply indicates that the ignition is on.
Not all these features are on all levels of firmware, but trying to use a feature that isn't there will have no effect on the rest of the message.
There are no commas between any of these feature letters.

[currency symbol]
Any characters here will be used as the currency symbol in texts, instead of the default "£" sign

[name]
Any text here will included at the start of texts, to help identifying the mTrak unit

Notes:-
There is no direct way to find the existing settings.
The mTrak unit will replace all the settings each time a new preferences text is received.
The commas separate the items in the preferences texts, and must be included.
