CHAPTER 7. LISTING / DESCRIPTIONS OF SERIAL SERVER SETTINGS
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 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 65535.
Configuration Files
contain all of the 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 Bits/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.
Delimiter 1, Delimiter 2 and Delimiter Removal
.
Delimiters and Delimiter Removal enable you
to control how characters received on a serial port are sent across the network. Delimiters are
ASCII characters specified by the user when configuring the serial server. The serial server
takes action when it recognizes the specified character(s) on its serial port.
Delimiter 1
is a
start delimiter.
The range of ASCII values is 0 through 255.
Delimiter 2
is an
end delimiter
. The range of ASCII values is 0 through 255.
Delimiter Removal
controls removing of Delimiter 1 and Delimiter 2 from the received
characters before the received characters are sent to the network.
