Definition and purpose of the sensor

Angle sensor "ESCORT DU-180” (hereinafter – sensor) designed to measure tilting angle of tilting parts of different machinery and mechanisms (for example: excavator bucket, jib crane). It provides, in cooperation with GPS/GLONASS terminal, transmission the accurate tilting angle of a controlled mechanism to the monitoring program with data displaying as the time diagram.

More detailed technical specifications are presented in the device's data sheet.

Basic Terms and Concepts

Serial number - code consisting of letters and numbers assigned to a device (sensor).

Data transfer protocol - a set of specific logical-level rules or conventions that govern the exchange of data between different programs or devices. For DU-180, the main transmission protocol is LLS via the RS-485 interface.

Data transfer mode - this is a type of boundary between two objects or nodes, which are regulated by a special accepted standard and implemented using established methods, tools and rules. DU-180 has the following operating modes:

  • RS-485
  • Frequency

Interface - a physical connection method and/or a set of software tools that allows data to be transferred between two or more devices.

RS-485 - digital data transmission mode. The sensor waits for a corresponding request from the receiving device. Works using the LLS protocol. Based on CNT, a value is generated in conventional units

Converter - digital converter RS-485 to USB (С200М или С200М2) for configuring wired sensors.

Frequency - zero angle corresponds to the frequency of 300 Hz. Maximum angle corresponds to the frequency of 480 Hz. Frequency is formed in the green wire.

Navigation terminal - the main element of the system for monitoring the operation of transportation carried out by means of satellite communication. Without it, it is impossible to control transportation, to determine the coordinates of the vehicle location. It collects information from sensors and on-board system of the vehicle, and then transmits it to the device/server, which belong to the controlling specialist.

Scope of Supply

 

Connection to the sensor, setup via the configurator on a PC

In order to connect DU-180 to the computer you will need an RS-485-USB adapter (we recommend using Escort C200M and C200M2). Strictly follow the connection algorithm described below. Download and install the configurator 1.0.2.38. This will install the drivers for the C200M converter. If other model of converter is used, install the driver for it.

1. Open the configurator

2. Connect the converter to the computer (the sensor must be de-energized)

 


3. Select (1) the COM port that appears (selected automatically if only one external device is connected as a virtual serial port)

 

4. Connect DU-180 to the converter and press (2) DU 180 in the configurator (this must be done in the first 15 seconds after connecting the sensor to the power supply or to the converter using the connector). After that, the DU-180 settings interface should be displayed. If this does not happen, then disconnect the sensor connector from the converter, the converter from the computer connector, close the configurator and start the connection from point 1.

Connection to the sensor, setup via mobile application on Android

Wired sensors can be connected to a smartphone with the Escort Configurator application. To do this, you will need:

  • A smartphone with a Bluetooth Android system with OTG technology support
  • An RS-485 - USB converter, for example, Escort C200m2
  • USB-OTG adapter for connecting the converter to a smartphone

Attention! You cannot update the firmware on the sensor through the application on the smartphone, this can only be done using a computer and the Bootloader program.

After connecting the sensor to the smartphone, you can connect:

  • Change the network address
  • Select the sensor operating mode

  • Connect the sensor to your smartphone according to the diagram
  • Check that the converter is turned on (there is a power indication), on some models the OTG mode must be enabled manually in the phone settings
 
Example of enabling OTG mode on OPPO smartphones
  • Select the RS-485 tab (1)
  • Select Fuel level sensor (2)
 
  • When connecting for the first time, the phone should ask for access to the converter, click OK
 
Providing access to the C200M2 in the app
  • If such a request does not appear and the sensor is not detected, try connecting additional power to the sensor according to the connection diagram, also check that the power indication on the converter is active and that the OTG mode is enabled on the smartphone
  • If, after asking for permission, you receive the error “Unable to connect the device,” this is normal. Just select the fuel level sensor again.
 
Error failed to connect device after requesting permission
  • If you are using a C200M inverter, you can connect an additional power supply to the inverter. To do this, you need to take a power supply for charging your smartphone with a microUSB connector and connect it to the C200M using the ADD PWR connector
  • Once connected successfully, you will see the main screen of the sensor.
