Description:
In order to carry through remote digital communication between computers with various standard series interfaces converter facilities or intelligent instruments, it needs inter exchange of standard series interface converter of compatible RS-232C and RS-485/422 standard is able to convert mono-end RS-232 signal to balance difference RS-485/422 signal and extend the communication distance to 1.2km. No external power but adopts a particular
RS-232 charge pump to drive the system, and gains electricity without initializing the RS-232 series interface. An internal zero delay auto transceiver and particular I/O circuit automatically control the data stream direction in stead of an handshake signal (for example RTS,DTR etc).There by in guarantees the function under RS-485/422 without changing the program compiled under RS-232 Full-duplex mode and assures the adaptation to current operation software and interface hardware. The transmission rate of 300-115.2kbps. Is capable of applying between host computers, host computer and is extensions or external equipment and forms point-to-point or point-to-multipoint remote and multi-communication network, It implements multi-machine response communication and commonly used in systems of industrial automation control all-one-card. Door safe, car parking, ATM, bus charge, eatery sell out, staff attendance management, and toll highway etc.

This particular module is suitable for tutorial use and perhaps for some hobbyists. Its drawback is that its I2C address is hard-wired to all zeros. (Note that I2C is a very effective 2-wire communications standard that is used by many small semiconductor devices such as microcontrollers and sensor peripherals.) If the address lines could be jumpered high or low, then several identical modules could be placed on the same I2C lines. I would therefore recommend the alternative module named the Mini PCF8591 AD DA Shell Module because it has that capability. It is also at least three times the price.
The IC permits only 8 bit data allowing only 256 steps in the analog output value or the digital output value. This is likely borderline for hobbyists who may want to build instrumentation or test equipment.
My tests show another frustration: A lower than expected analog output voltage. For a 4.88 volt supply the output is only 4.17 volts (85%) at maximum value setting. Since the maximum supply voltage is 8 volts, increasing the supply to 6 volts may get a 5 volt result. I did not remove the green LED and related resistor to see if the problem was simply an excess current drain from the IC’s AOUT.
