X=0
– the number of an activated output
Y
– speed km/h, which activates the selected discrete output when being violated
The command «
ACCELALARM
» sets acceleration and braking values which violation is
notified to the driver.
ACCELALARM X,Y,Z,A
X=0,…5 – the number of an analogue input whose data are replaced by acceleration and
braking
Y
– braking limit activating the output
Z
– acceleration limit activating the output
А – the number of an activated output
7.4 RS-485 Interface
7.4.1 Working with a digital fuel level sensor
The tracker allows a simultaneous connection of three fuel level sensors to the RS-485 bus.
The tracker interrogates sensors one by one and transmits fuel level and temperature values in
the “FUEL” data block.
Before connecting to the tracker, it is necessary to set the sensors:
- set the network address (addresses 0,1,2 will be interrogated by the tracker by default);
- select the interface speed 19200 bauds;
- switch off the automatic data output.
Connect sensors to the contacts 6, 18 of the MF-24F plug. Connection layout is provided on
the Figure 11.
It is necessary to activate the “FUEL” data block transmission with the
«PROTOCOL»
command. The current fuel level value is displayed in the response to the «
FUEL
» command.
If necessary, the addresses of the sensors interrogated might be changed by the
«LLS485
X,Y,Z»
command.
X,Y,Z are addresses of interrogated sensors and addresses 0,1,2 are interrogated by default.
