Port Settings
Protocol
Select the protocol type from the pull down menu for the
selected channel.
Flow Control
Flow control manages data flow between devices in a network
to ensure it is processed efficiently. Too much data arriving
before a device is prepared to manage it causes lost or
retransmitted data. None is the default.
Channel 1
: None, Xon/Xoff, Xon/Xoff Pass Chars to Host
or CTS/RTS (hardware).
Channel 2
: None, Xon/Xoff or Xon/Xoff Pass Chars to
Host
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.
Pack Control
Enable Packing
Select the checkbox to enable packing on the WiPort.
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 WiPort 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 Immediate
After the detection of the byte sequence, indicates whether to
send the data frame or the entire buffer. Select
Yes
to send
only the data frame. The default setting is No.
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.
