CHAPTER 7. 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 of 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.
x
Data Bits
controls the number of bits of data in each character. Options include 5, 6, 7 or 8
data bits.
x
Parity
controls the error checking mode. Options are No Parity, Odd, Even, Mark or Space.
x
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.
