(Optional, if included)
Possible baud rates: 9,600 - 19,200 - 38,400 - 115,200.
Length: 8 bits
Stop bits: 1 bit
Paring bit: none
Data output modes:
The RS-232 output on Ron systems has two modes of data output that are selectable

Continuous mode:
There are two continuous modes. Each system is factory set to one or the other.
1. Continuous - unconditional constant flow(default): the displayed value will be
output at a rate of about once per second.
2. Changes - upon value change: the displayed value will only be output when there is
a change in the reading. If there is a steady change in value, a reading will be output at
