manage it causes lost or retransmitted data.
Baud Rate
The unit and attached serial device, such as a modem, must agree on 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 WFS802g.
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 WFS802g 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.
