The following serial server properties are ordered alphabetically to assist you in finding the
information you need.
Baud Rate
When in VCOM mode this parameter is grayed out, because its value is controlled by the VCOM
driver on the computer.
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 230.4k. (Refer to Appendix B for specific baud rates that
are supported.)
Character Count
Character Count controls the maximum number of characters to buffer before sending the
characters to the network. Larger values will decrease the number of network packets, but will
increase the amount of time to receive characters. Smaller values will increase the number of
network packets, but will decrease the amount of time to receive characters. The range is 1
through 8192.
Configuration Files
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 (fromVlinx 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
When in VCOM mode these parameters are grayed out, because their value is controlled by the
VCOM driver on the computer.
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.)
