5.Setting and display

1)interface(Output level value)

- Interface: This device provides RS232 data port, analog output voltage  

- RS232 serial port: The default is 9600 baud, level sensors in real time values for each

measured pass 10S (in units of 0.1mm). The baud rate can be modified according to the user

needs to be done, the time interval data transmission

-Voltage sampling port:The output voltage of the voltage output from the current level value and

the size of the set range determined.

2)Digital display content                                      

-Liquid level value:Shown as picture 2,current level value is 242.0mm

-Signal Value:as shown in picture 3,the value is 3,max9,due to the specificity ofultrasonic,Signal value is not the bigger the better, the control signal is 2 or 3 when the tank is full of oil.

3)Parameter setting

A.Setting the signal valuewhen the poor signal (too big or too small) touch of a button press "1" key for 8 seconds or more to enter the signal reception sensitivity settings, press the "2" key signal sensitivity increases, press "3 "key signal sensitivity decreases, press" 1 "key for 8 seconds or more, save sensitivity digital interface jump back to Figures 2 and 3 switching state.Without having to power transmission, can modify the signal sensitivity, Sensitivity defaults to 20

B.Setting the device full measuring Shown in Figure 5, when the modified full-scale equipment, while long press touch of a button "1 and 2" button for 8 seconds or more full-scale settings, press the "2" key full-scale increases, press the "3" key full scale decreases, press "1" key for 8 seconds or more, save full-scale sensitivity digital interface jumps back to Figures 2 and 3 switching state. Equipment needed to re-power program will be executed.Full measuring range defaults to 80 cm.

C.Setting the baud rateAs shown in Figure 6, when devices change the baud rate, while long press touch of a button, "2 and 3" button for 8 seconds or more full-scale settings, press the "2" key to increase the baud rate, press "3 "key to reduce the baud rate, press" 1 "key for 8seconds or more, save baud rate, the digital interface jump back to Figures 2 and 3 switching state. Equipment needed to re-power program will be executed. The default baud rate is 96 * 100= 9600

D.Set device algorithm execution(Not suggest to modify)Shown in Figure 7, when the modified algorithm devices while long press touch of a button, "1, 2 and 3" key 8 seconds algorithm settings, saving algorithm mode, the digital interface jump back to Figures 2 and 3 switching state. Equipment needed to re-power, the program will execute the new settings. Algorithm defaults to "1" mode.

E.Wiring

- Power cord: Coarse red (car battery positive), bold black(Car Ground).

-Signal line: yellow (connected user devices (GPS) of the RS232 RX line), blue (user equipment

connected to the RS232 TX line), green (user equipment connected to a voltage sampling port),

thin black (user equipment to).

-Ultrasonic probe line: 9 meters long, plug end of the terminal 6 holes

6.Installation guide

A.Probe line extension cable installation

- Extension cord should outsource a protective cover, such as heat-shrink tubing. When the

vehicle wiring along the skeleton or the location of the original wiring go, extension cords and

vehicle heating parts, components should be at least 20 cm distance.

- Extension cord can be lengthened if necessary, the total length of the probe line does not allow

more than 15 meters.

-Power red wire car battery positive and black wire to the car's Ground
