7.5.3 Data/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.
7.5.4 Handshaking
This setting controls handshaking. You can select XON/XOFF or Disabled for this setting.
7.5.4.1 Disabled (No Handshaking)
If handshaking is disabled, the UPS transmits and receives data via the serial port, ignoring
all inputs from handshaking lines.
7.5.4.2 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 receiving 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.
7.5.5 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.
7.5.6 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, which you select
when configuring the port using the Setup Port screen.
