Guidelines
1 The Serial ASCII Protocol ignores white space between fields.
2. The Checksum is the decimal sum, modulo 256, of all the characters from after the initial framing character (STX), up to and including the “:” character.
3. Due to floating point conversions, a floating point value sent to the drive may not be exactly equal to the value received from the drive.
4. Address 0 is a global address. All drives will process a message sent to address 0 but will NOT reply. Address 255 is a default address and all drives will process messages sent to Address 255 and WILL return a reply. Therefore, when multi-dropping PC830 drives, assign a unique address (between 1-254, inclusive) to each drive.
