retransmitted data. See
Table 5-5. Flow Control Options
for
available flow control options.
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, and
921000.
Data Bits
Indicates the number of bits in a transmitted data package.
The default is 8.
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.
The default is 1
Pack Control
Enable Packing
Select the checkbox to enable packing on the MatchPort.
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. Two bytes must occur sequentially to indicate to the
MatchPort the end of the data collection.
Send Frame Immediately
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
.
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 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.
