TCP/IP socket (WINSOK mode)
Communication
Mode
Working mode option
TCP Data Mode
There are two parameters for the TCP data mode: [raw] and [telnet], the first is for fully
transparent transmission, and the second means that the socket data is in accordance with
TELNET and RFC2217 standard. Control code is added to the data received by the server from
the serial ports and then sent to other nodes in the Ethernet through socket.
Local Port
Port number (default as 1001, 1002…)
CR As
There are four parameters: [none], [cr], [lf], and [cr-lf]. [none] means that the server will not send
an “ENTER” received from a serial port to the Ethernet; [cr] means that the server will send an
“ENTER” received from a serial port to the Ethernet just as it is; [lf] means that the server will
change an “ENTER” received from a serial port to a “NEW LINE” and then send it to the
Ethernet; [cr-lf] means that the server will change an “ENTER” received from a serial port to an
“ENTER” and a “NEW LINE” and then send them to the Ethernet.
LF As
There are four parameters: [none], [cr], [lf], and [cr-lf]. [none] means that the server will not send
an “ENTER” received from a serial port to the Ethernet; [cr] means that the server will send an
“ENTER” received from a serial port to the Ethernet just as it is; [lf] means that the server will
change an “ENTER” received from a serial port to a “NEW LINE” and then send it to the
Ethernet; [cr-lf] means that the server will change an “ENTER” received from a serial port to an
“ENTER” and a “NEW LINE” and then send them to the Ethernet.
Sessions
Number of hosts connected to the device (up to six)
Strip NULL
Authentication
It is possible that the server send a request for authentication when connected, the connection
will be cancelled if the user’s name and the password are incorrect. This configuration option
has two parameters: [none] and [local].
Note: If [local] is selected for the authentication, the
users should be added correspondingly, and it is possible to set the operation authority of the
users to the serial ports; if no user is added, the [authentication] set is invalid, which means that
the connection will be permitted to be established even the input user name and password don’t
exist.
Auth Prompt
If this option is set to yes, a login hint will show up when connecting the server: (Login: and
Password)
SERVER First
Server priority status
Used as a TCP client
Peer Host
The IP address pointing to the server end
Peer Port
The port number pointing to the server end
Connect
Issuing a connect includes four situations: [always], [char], [dcdon], and [dsron]:
[always] means that the server starts a connection at power up and reconnects immediately if
the connection is broken;
[char] means that the server starts a connection as soon as the corresponding port receives the
data;
[dcdon] means that the server starts a connection when DCD of the corresponding serial
RS-232 port is set to a high value;
[dsron] means that the server starts a connection when DSR of the corresponding serial RS-232
port is set to a high value;
