12.3.3 Data/Stop
The data size and stop bits of the equipment connected to this port 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, set your equipment to NO
PARITY.
12.3.4 Handshaking
This setting controls handshaking. You can select XON/XOFF or Disabled for this
setting.
S XON/XOFF – If handshaking is enabled, the UPS 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 UPS halts transmission until an XON
command is received. In the same way, if the terminal receives an XOFF
command, the UPS expects the terminal to halt transmission until the UPS
sends an XON command.
S Disabled (No Handshaking) – If handshaking is disabled, the UPS transmits and
receives data via the serial port, ignoring all inputs from handshaking lines.
12.3.5 Save
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.
12.3.6 Default Settings
The following are the default configuration settings for the serial communication
ports:
Port 1 Remote Monitor 300 baud 8/1 Handshaking Disabled
Port 2 Terminal 9600 baud 8/1 Handshaking Disabled
Each communication port on the UPS operates in one of five modes that you select
when configuring the port using the Setup Port screen.
