a speed or baud rate to use for the serial connection. Valid baud rates
are 300, 600, 1200, 2400, 4800, 9600 (default), 19200, 38400,
57600, 115200, 230400, 460800, or 921600.
Data Bits Indicates the number of bits in a transmitted data package.
Parity Checks for the parity bit. The default is None.
Stop Bits The stop bit follows the data and parity bits in serial communication. It
indicates the end of transmission.
Port Settings
Enable Packing Select the checkbox to enable packing on the WFS802b.
Two firmware-selectable packing algorithms define how and when
packets are sent to the network. The standard algorithm is optimized
for applications in which the unit is used in a local environment,
allowing for very small delays for single characters, while keeping the
packet count low. The alternate packing algorithm minimizes the
packet count on the network and is especially useful in applications in a
routed Wide Area Network (WAN). Adjusting parameters in this mode
can economize the network data stream.
Idle Gap Time Select the maximum time for inactivity. The default time is 12
milliseconds.
Match 2 Byte
Sequence
Use to indicate the end of a series of data to be sent as one group. The
sequence must occur sequentially to indicate to the WFS802b end of
the data collection.
Match Bytes Use to indicate the end of a series of data to be sent as one group. Set
this value to 00 if specific functions are not needed.
Send Frame Only After the detection of the byte sequence, indicates whether to send
the data frame or the entire buffer. Select True to send only the data
frame.
Send Trailing
Bytes
Select the number of bytes to send after the end-of-sequence
characters.
Flush Input Buffer (Serial to Network)
With Active
Connect
Select Yes to clear the input buffer with a connection that is initiated
from the device to the network.
With Passive
Connect
Select Yes to clear the input buffer with a connection initiated from
the network to the device.
At Time of
Disconnect
Select Yes to clear the input buffer when the network connection to or
from the device is disconnected.
Flush Output Buffer (Network to Serial)
With Active
Connect
Select Yes to clear the output buffer with a connection that is initiated
from the device to the network.
With Passive
Connect
Select Yes to clear the output buffer with a connection initiated from
the network to the device.
At Time of
Disconnect
Select Yes to clear the output buffer when the network connection to
or from the device is disconnected.
