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, or 230400, 460800, or 921600
Note:
I
t is recommended to use hardware flow control for baud
rates of 38400 and higher or it could result in data loss.
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 to enable packing on the xPico.
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.
Disabled by default.
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 end
of the data collection to the xPico. The default 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 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. The default is
None
.
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. The default is
No
.
With Passive Connect
Select
Yes
to clear the input buffer with a connection initiated
