Description of Serial Server Properties
The following serial server properties are ordered alphabetically to assist you
in finding the information you need.
Baud Rate is the communication speed of the link between the serial server
and the device attached to its serial port. Both these devices must be
configured to operate at the same baud rate. Baud rate values range from 75
to 230,400 Baud. (Refer to Appendix B for specific baud rates that are
supported.)
Character Count controls the maximum number of characters to buffer
before sending the characters to the network. Larger values decrease the
number of network packets, but increase the amount of time to receive
characters. Smaller values increase the number of network packets, but
decrease the amount of time to receive characters. The range is 1 through
8192.
Configuration files contain all configuration settings for the serial server.
When the serial server settings have been configured you can save the
settings using Vlinx Manager. Existing configuration files can be Opened (from
Vlinx Manager), which loads them into the serial server. This allows the same
configuration to be applied to multiple serial servers, or to reload a previously
used configuration.
Data/Parity/Stop Bits. The number of Data bits, type of Parity and number
of Stop bits selected define the serial port parameters at which the serial
server will operate. These parameters must be configured to match the
parameters set on the serial device connected to the serial server's serial port.
 Data Bits controls the number of bits of data in each character. Options
include 5, 6, 7 or 8 data bits.
 Parity controls the error checking mode. Options are No Parity, Odd,
Even, Mark or Space.
 Stop Bits controls the number of bits to indicate the end of a character.
Options include 1, 1.5 and 2. (1.5 bits is only valid when 5 data bits is
selected, which is rare. The 2 stop bits setting is only valid when 6, 7 or 8
data bits is selected.)
The Default Gateway address sets the default route to remote networks,
enabling users to access the serial server from outside the local network.
