Configuration Using Web-Manager
WiPort™ User Guide 22
disables communication through the serial port.
Port Settings
Protocol Select the protocol type from the pull down menu for the
selected channel. RS-422/485 4-wire and RS-485 2-wire
options are available on the WiPort-485 only.
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.
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 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.
