7.6.2 Connection parameters for RS-232/RS-485 interface
To connect DUT-E S7 Radiobox RS to Telematics terminal , you should configure parameters of
the RS-232/RS-485 in the Interface submenu Service S6 DUT-E software (see figure 32):
1) Select the data transfer protocol from the dropdown list Output Protocol Type:
Modbus or DUT-E COM (DUT-E COM by default).
For DUT-E COM areas for additional settings are available:
a) in the field RS Settings you can select:
•
Mode of the sensor outgoing messages transmission from the dropdown list Data
Sending Mode :
- On Request — automatic data transfer is off; only data transfer upon the terminal
demand is on (mode by default);
- Auto HEX — hexadecimal format of the automatic data output;
- Auto ASCII — text format of the automatic data output;
- Auto ASCII EXT — extended text format of the automatic data output. In case it is
used, fields of additional parameters are available for editing:
- Text Message Prefix and Text Message Suffix which respectively establish the
beginning and the end of the transmitted data in the text format (32 characters at a
maximum).
• In the field Sending Interval, s you can set the value of the time interval for which
the sensor transmits data to the connected tracking device. The time interval values for
the messages output may vary from 1 to 255 s (increment size 1 s). 1 s is set by
default.
b) In the field DUT-E COM Setting Mode you can select from the drop-down list
Output Parametr Type Measure :
• y.e. — fuel level in the tank in dimensionless units (0...1000 d.u.);
• mm — level of fuel in the tank (mm), step 0.1 mm;
• Litres — volume of fuel in the tank (l), step 0.1 l (parameter by default);
• % — volume of fuel in the tank (%), step 0.4 %.
2) Select the RS232/485 Baud Rate from the following range of values 2400; 4800; 9600;
19200; 38400; 57600; 115200 bit/s (19200 bit/s by default).
