Working Principle

Assembly Options

With NEMA17 Plastic Flange

ADM42 Series RS485 Stepper Motor Controller with NEMA17 size plastic flange:

Direct Mount to NEMA17 Motor

When the RS485 Stepper Motor Controller without NEMA17 Plastic Flange, it can be assembled to NEMA17 Stepper Motor directly:

NEMA17 Integrated Stepper Motor, more concise and aesthetically pleasing:

DIP Switch Configuration

RS485 Stepper Motor Controller, using 6 DIP switches for setting the communication baud rate and device ID.

Device ID Setting (SW1 ~ SW4)

The formula for calculating the ID: ID = 1×SW1 2×SW2 4×SW3 8×SW4. The default ID value is 0, broadcast mode accepts data but does not return data.

Communication Baud Rate Setting (SW5 ~ SW6)

CRC Check Routine (C#)

Uint16 Funct_CRC16(unsigned char * puchMsg, Uint16 DataLen)
{
    Uint16 i, j, tmp;
    Uint16 crcdata = 0xFFFF;
    for(i = 0; i < DataLen; i )
    {
        crcdata = (*puchMsg) ^ crcdata;
        puchMsg ;
        for(j = 0; j < 8; j )
        {
            tmp = crcdata & 0x0001;
            crcdata = crcdata >> 1;
            if(tmp)
            {
                crcdata = crcdata ^ 0xA001;
            }
        }
    }
    return crcdata;
}
