Wireless Serial Server
User Manual
Configuration and
setup
discard data can be more than, less than, equal to, or non-equal to a specific number of data (in Bytes). Within
the timeout interval, if the condition is not satisfied, the data in buffer will be packed and sent out.
Max Bytes
:
SW550XC will transmit the serial data in its buffer when the specified length in the unit of bytes
has reached
.
The range of maximum bytes is between 1 to 1452 bytes
.
Enable this option if you would like
SW550XC to queue the data until it reaches a specific length
.
This option is disabled by default
.
Character
:
SW550XC will transmit the serial data in its buffer when it sees the incoming data include the
specified character
(
in hexadecimal
(
HEX
)
format
).
This field allows one or two characters
.
If character
delimiter is set to 0x0d, SW550XC will push out its serial buffer when it sees 0x0d
(
carriage return
)
in the serial
data
.
This option is disabled by default
.
Send one character every
□
ms
:
SW550XC will save packets received from the network to its buffer, while
kepp sending one character every designate time interval
.
Network to Serial Packet Delimiter
:
This group of options is the same as the delimiters described above, but
they control data flow in the opposite direction
.
SW550XC will store data from the network interface in its
queue
.
Until one of the delimiter conditions described above is met then SW550XC will send the data over to
the serial interface
.
Character Send Interval
:
This option specifies the time gap between each character
.
When set to one second
(
1000ms
)
, SW550XC would split the data in the queue and only transmit one character
(
a byte
)
every 1 second
.
The maximum value for this option is 1000 milliseconds or 1 second
.
This option is disabled by default
.
Response Interval Timeout
:
This option only affects the Request & Response Mode and has no effect on the
Transparent Mode
.
Please see the discussion about Request & Respond Mode versus Transparent Mode
later
.
When TCP data is received
(
a request from network
)
and passed to serial
device side, the SW550XC
device will wait for the set time before transferring another TCP data if the serial
device side did not receive
any data
(
no response from the serial device
).
The maximum value for this option is 60,000 milliseconds or 1
minute
.
Serial
Serial FIFO
:
By default, SW550XC has its First
-
In
-
First
-
Out
(
FIFO
)
function enabled to optimize its serial
performance
.
In some applications
(
particularly when the flow control mechanism is enabled
)
, it may deem
necessary to disable the FIFO function to minimize the amount of data that is transmitted through the serial
interface after a flow off event is triggered to reduce the possibility of overloading the buffer inside the serial
device
.
Please note that disabling this option on baud rates higher than 115200bps would noticeably reduce
the data integrity
.
Serial Buffer
:
By default, SW550XC will empty its serial buffer when a new TCP connection is established
.
This means that the TCP application will not receive buffered serial data during a TCP link breakage
.
To keep
the serial data when there is no TCP connection and send out the buffered serial data immediately after a
TCP connection is established, you can disable this option
.
