SW5502C
Wireless Serial Server
User Manual
Link modes and
Applications
(
usually a Terminal Server
)
with a Telnet program
.
Telnet programs in Windows
/
Linux usually
require special handshaking to get the outputs and formatting to show properly
.
The SW550XC
series will interact with those special commands
(
CR
/
LF commands
)
once Reverse Telnet
application is enabled
.
Pair Connection Master
:
This application is used when the user want to pair two serial devices
over the Ethernet network
.
1.
IP Filter
:
This option will enable the Source IP option below
.
When this option is checked,
SW550XC will block or filter out all other IP addresses from accessing the COM port except the
one specified in the
Source IP
.
2.
Source IP
:
This option specifies the remote
client
’
s Source IP which will be transmitting data to
our TCP Server
(
on SW550X
).
In other words, our TCP Server will only allow data from this IP
address to flow
(
hence its own name implies Source IP
).
Note that only one source is allowed
.
3.
Local Port
:
This option specifies the port number that the TCP Server
(
on SW550X
)
should listen
to
.
It is also used by the remote TCP client to connect to the TCP
server
.
The default local port
is 4660
.
You can enter different port number in this option
.
4.
Maximum Connection
:
This option specifies the maximum number of remote devices
/
clients
(
with maximum of 4 clients
)
that can be connected to the serial device on this COM port
.
5.
Response Behavior
:
This option specifies how SW550XC will proceed or behave when it receives
requests from remote connected hosts in which we will have the following options
:
Request & Response Mode
:
Under this mode, the COM
port on SW550XC will hold requests from
all other remote
connected hosts until the serial device replies or the Response Interval Timeout
takes into effect to discard it; however, unrequested data sent from the serial device would be
forwarded to all connected hosts
.
Additionally, user can specify how a
reply message from the
serial device will be sent to the remote connected hosts with two possible options
:
o
Reply to requester only
:
The COM port will reply to the remote connected host who has
requested the data only
.
o
Reply to all
:
A reply is sent to all remote connected hosts
.
Transparent mode
:
The COM port
on SW550XC will forward requests from all remote connected
hosts to the serial device immediately and reply to all remote connected hosts once it receives
data from the serial device
.
