Rs 232 waveforms 8 This is the instruction bytes. Note that the voltage swing of the instruction waveform is about +/-10 V. This is typical of the USB to RS 232 converter to which the device is connected This is a closeup of the instruction byte 2. The "S" on either end represents the start and stop bits respectively. The start bit is always positive and the stop bit is always negative. The bit sequence is Start, 0, 1, 2, 3, 4, 5, 6, 7, Stop. The data is output with the least significant bit first, so the byte shown is actually 0011 in binary or 32+16+2+1 = 51 in decimal. EMLAB
