What is the 8-N-1 ASCII protocol mentioned in the manual?
The Servida Motor uses an asynchronous serial interface often described as a “three wire implementation of RS-232.” Asynchronous communications require a stable environment: if any bit of a transmission is lost, there is a high probability that the remainder of any transmitted message will be misunderstood. It is therefore necessary to carefully define the structure of the transmission. A serial bit is a defined period of time, and the state of the bit can either be a 1 or a 0, depending on the voltage state of the transmit line during the duration of the serial bit. When the RS-232 is in the idle state (waiting to transmit a message) it rests in the high (on) state. When a character is to be transmitted the TxD line is brought low for a carefully defined period of time, the time period of the start bit is a function of the BAUD rate. This low state is called the start bit. Immediately following the start bit are a number of data bits. The Servida Motor must use 8 data bits, and this i
