Baud Rate 
Select “Baud Rate” to change the rate the modem transfers Data bites per second, the DS displays the 
following: Default is 9600  

 

 

 

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. 

 

Select “Stop Bits” the DS displays the following: Default is 1.
