Pre-defined timeouts are set using switches 8 through 11.
Resistor selectable baud rates are set by inserting a
through-hole resistor (R-9) on the circuit board.
Timeout selections are equal to one character time at the
indicated baud rate. Setting the converter to 9600 will
generally work at 9600 and higher baud rates.
In RS-422
mode, timeouts are not required.
