These settingsdetermine the number of bits transmitted per ASCII character. The data size and stop bitsyou 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 databits/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, youshould set your equipment to NO PARITY.7.4.4 HandshakingThis setting controls handshaking. You can select XON/XOFF or Disabled for this setting.7.4.4.1 Disabled (No Handshaking)If handshaking is disabled, the UPS transmits and receives data via the serial port, ignoringall inputs from handshaking lines.7.4.4.2 XON/XOFFIf handshaking is enabled, the UPS uses special characters (XON and XOFF) to handshakewith the host terminal. The XON character is defined to be ASCII value 11 hex, and theXOFF character is defined to be ASCII value 13 hex. Upon reception of an XOFF command,the UPS halts transmission until an XON command is received. In the same way, if theterminal receives an XOFF command, the UPS expects the terminal to halt transmissionuntil the UPS sends an XON command.7.4.5 SaveSet 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.7.4.6 Default SettingsThe following are the default configuration settings for the serial communication ports:Port 1 Remote Monitor 300 baud 8/1 Handshaking DisabledPort 2 Terminal 9600 baud 8/1 Handshaking DisabledEach communication port on the UPS operates in one of five modes which you select whenconfiguring the port using the Setup Port screen.
