Serial Port Configuration
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

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
