Interface
- is a physical connection method and/or a set of software tools by which data
is transferred between two or more devices.
RS-485
- digital data transmission mode. The sensor waits for a corresponding request
from the receiving device. Works under the LLS protocol. Based on CNT, a value is
formed in arbitrary units of the selected range (1-1023 c.u. or 1-4095 c.u.)
Active (periodic) RS-485
- a variation of the above mode of operation, in which the
sensor, without waiting for a request from the receiver, itself transmits data packets
every 2 seconds.
RS-485 Modbus
- is a variation of RS-485. The only difference is that data transfer is
carried out using the
Modbus
protocol. Available only for TD-500.
Analog
- is a mode in which the corresponding voltage is formed on the basis of CNT
in the approximate range of 0.2-5V (TD-500) or 0.2-9V (TD-150).
Frequency
- the mode in which the corresponding frequency in Hz is formed on the
basis of CNT (301-1323 Hz with a range of values 1-1023; 301-4395 Hz with a range of
values 1-4095)
Pulse
- a mode in which a burst of pulses with a frequency of 27 Hz is formed on the
basis of CNT. The number of impulses in a pack corresponds to the measured fuel level.
The minimum level corresponds to a pack of 2 pulses, the maximum - a pack of 1025
pulses. Available only for TD-500.
Navigation terminal
- is the main element of the system for monitoring the operation
of transport, carried out using satellite communications. Without it, it is impossible to
control the transport, to determine the coordinates of the location of the vehicle. It
collects information from sensors and the onboard transport system, and then
transfers it to a device / server that belongs to a specialist who controls the process.
