(remote on) and RM=0... (remote off) and viceversa. The time can be calculated with the formula:tmin = 2x(1/baud rate) + 60μs.If at the beginning no SPACE CR command is recognizable, theoscilloscope pulls the TxD line low for approx. 0.2ms and causesa break on the PC.Data CommunicationAfter successfully being set to remote control mode, theoscilloscope is prepared for command reception.RS-232 Interface
