Word Size
The word size is the measurement of the actual data bits in a transmission. Which setting you choose
depends on what information you are transferring. For example, standard ASCII has values from 0 to
127 (7 bits). Extended ASCII uses 0 to 255 (8 bits). If the data being transferred is simple text
(standard ASCII), sending 7 bits of data per packet is sufficient for communication. A packet refers to
a single byte transfer, including start/stop bits, data bits, and parity.

Select “Word Size” and the DS displays the following: Default is 8
Stop Bits
The Stop Bits are used to signal the end of communication for a single packet. Since the data is
clocked across the lines and each device has its own clock, it is possible for the two devices to become
slightly out of sync. Therefore, the stop bits not only indicate the end of transmission but also give the
computers some room for error in the clock speeds. The more bits that are used for stop bits, the
greater the lenience in synchronizing the different clocks, but the slower the data transmission rate.
