5 Introduction to the Nano Pump
One start bit and one stop bit are always used (not selectable).
Per default, the module will turn into 19200 baud, 8 data bit with no parity.
Forced Cold Start Settings
Switches 1 and 2 do not force storage of this set of parameters in non-volatile 
memory. Returning switches 1 and 2 to other positions (other than being both 
up) will allow for normal operation.
If you use the following switch settings and power the instrument up again, a 
forced cold start has been completed.
To return to normal operation, set switches back to your GPIB or RS 232 
configuration settings.

loading errors.
