13.4.3Data/Stop

The data size and stop bits of the equipment connected to this port. These settings determine the number of bits transmitted per ASCII character. The data size and stop bits you specify depend on the configuration of your equipment.

For Port 1, the data size must be set to 8, with 1 or 2 stop bits. Settings of 7 data bits/1 stop bit and 7 data bits/2 stop bits are available for Port 2.

NOTE: When connecting a computer running a terminal emulation program, you should set your equipment to NO PARITY.

13.4.4Handshaking

This setting controls handshaking. You can select XON/XOFF or Disabled for this setting.

DDisabled (No Handshaking)

If handshaking is disabled, the SSBM transmits and receives data via the serial port, ignoring all inputs from handshaking lines.

DXON/XOFF

If handshaking is enabled, the SSBM uses special characters (XON and XOFF) to handshake with the host terminal. The XON character is defined to be ASCII value 11 hex, and the XOFF character is defined to be ASCII value 13 hex. Upon reception of an XOFF command, the SSBM halts transmission until an XON command is received. In the same way, if the terminal receives an XOFF command, the SSBM expects the terminal to halt transmission until the SSBM sends an XON command.

13.4.5Save

Set to YES to save any changes to configuration settings upon exit from the Setup screen. Set to NO if you do not want to save any changes.
