Data Bits
Select 7 or 8 Data Bits.
Parity
Select Even, Odd, or None. The default is None.
Stop Bits
The stop bit follows the data and parity bits in serial communication.
It indicates the end of transmission. Select 1 or 2 stop bits.
Pack Control
Enable Packing
Select the checkbox to enable packing on the Wi232.
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 Wi232 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 when the network connection to
or from the device is disconnected.
At Time of Disconnect
Select Yes to clear the input buffer with a connection initiated from
the network to the device.
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.
