Cisco Systems DS71-MD4 Manual De Usuario

 

Handshaking, Baud Rate, Word Size, Stop Bits, and Parity are configured through either the serial or 
Ethernet ports using the menus.  Xon/Xoff, RTS and DTR Line Drivers can only be configured through 
the phone line via a modem.  The default settings are 9600bps, 8 data bits, no parity, one stop bit, 
Xon/Xoff Off and RTS/DTR High. 

 

IMPORTANT: Changing the Host module serial port configuration could create a 
communications lock-out if the terminal computer serial port configuration does not match the 
host module. 

 

 

 

 

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
