Status: Check this combo box to enable serial communication
Mode: Select one mode among Server, Client and Mixed.
This mode is to select the communication method based on TCP. TCP is the protocol which
establishes the connection before data communication. In server mode, WIZ6000 waits for
the connection from a clie nt. In client mode, WIZ60 00 operates as client at the TCP Client
mode on the process of connection, and tries to connect to the server ’s IP and Port. Mixed
modes supports both of Server and Client at the same time.
Below describes in details regarding each mode
- TCP server mode
In orde r to o perate thi s mode, Lo cal IP, Subnet, Gateway Addre ss and Local Po rt
Number should be co nfigured. In monitoring a pplications, the serve r mod e can be
useful since it can listen for any connection from clients, and establish a connection for
remote management.
1. A client connects to the WIZ6000 which is in TCP Server mode.
2. As the connection is established, data can be transmitted in both directions – from
the host to the WIZ6000, and from the WIZ6000 to the host
- TCP client mode
In TCP Client mode, your module will attempt to connect to a specified server.
In order to operate this mode, Local IP, Subnet, Gateway Addre ss, Serve r IP, and
Server port number should be set. If the server IP has a domain name, please use the
DNS function.
1. Whe n po wer i s supplied, WIZ6 000 board operating as T CP client mo de actively
establishes a connection to the server.
2. Once the connection is established, data can be transmitted in both directions – from
the host to the WIZ6000 and from WIZ6000 to the host
- Mixed mode
In this mod e, WIZ6000 normally operates as a TCP Server and waits for a connection
request from a client. However, if WIZ6000 re ceives data from the serial device before
connection is established, WIZ6000 changes to the client mode and sends the data to
the server. Therefore, in the mixed mode, the server mode has higher priority than the
client mode. Mixed mode t akes advantages of both client and serv er mode. The client
mode may b e used fo r sending out em ergency reports in an u rgent situation while the
server mode may be used for remote management.
