TX, – When the *BW is open or held low, the TX output delivers
asynchronous serial with an RS232 format, except voltages are 0-
Vcc. The output is an ASCII capital “R”, followed by three ASCII
character digits representing the range in inches up to a maximum
of 255, followed by a carriage return (ASCII 13). The baud rate is
9600, 8 bits, no parity, with one stop bit. Although the voltage of 0-
Vcc is outside the RS232 standard, most RS232 devices have
sufficient margin to read 0-Vcc serial data.
If standard voltage
level RS232 is desired, invert, and connect an RS232 converter
such as a MAX232
