Usage
The USB / RS-485 converter is used to connect the fuel level probe RS-485 interface (or fuel filler cap) to a PC-class computer via a USB port
and simultaneously to power the device - the receiver with + 12V DC voltage.
How the converter works
The basic element of the converter - integrated circuit FT232BL- converts USB standard signals into standard UART signals.
The speed of transmitted data ranges from 300bps to 115200bps. The voltage levels of the UART standard are converted to voltage levels RS-485
using the SP485 system. The control of this system is provided by the optocouplers connected to the outputs of the FT232BL system, and the supply
via the + 5V / + 12V converter circuit with a 1W output power with an attached LDO stabilizer system with an output voltage of + 5V.
Green LEDs indicate power supply and red LEDs indicate data transmission. The converter can power the receiver (eg fuel level probe or fuel filler cap)
with a nominal voltage of approx. + 12V and power consumption max. 75mA. The converter uses internal current protection against the effects of shorting
the output power terminals (+ Uzas and -Uzas).
How to connect the converter
The converter should be connected to a fuel level probe type CS-27 / RS / U (or CS-27 / RS-232) or a fuel filler type BAK-Q60 (Q80) and a computer.
Detailed schema can be found in the user's manual.
