Menu Default Descriptions

Operation Mode COM

Select the operation protocol, which the serial port would use.

Disable

Do not use this port.

COM

Use the serial port of Eddy as the COM ports of Windows 2000/XP/2003/Vista operated PC.

TCP Server

Eddy works as a socket server, waiting for the client connection on the network.

Socket number for awaiting connections can be set in ‘Local socket port’ field.

All data between the socket and the serial port is transferred untouched after the socket

connection is established.

TCP Client

Eddy acts as a socket client in this mode. It tries to connect to the server IP address and the

socket number assigned when a certain server waits for connection on the network.

All data between the socket and the serial port is transferred untouched after the socket

connection is established.

TCP Broadcast

Eddy works as a server, accepting up to 5 simultaneous connections from socket clients.

Data transmitted from Eddy is broadcast to each socket client.

TCP Multiplex

Eddy works as a server, accepting up to 5 simultaneous connections from socket clients. The

difference between TCP Broadcast and TCP Multiplex is that Multiplex allows each socket to

communicate exclusively. That is, serial data in response are only transferred to the sender

socket.

UDP Server

Eddy works as a UDP server, waiting for UDP connection from the client on the network.

Socket number for awaiting connections can be set in ‘Local socket port’ field.

Once a UDP packet is received to the socket that waits for the connection, the data is

transmitted to the serial port. The data input from the serial port is put into UDP packets, which

eventually are sent to the client.

UDP Client

When the data is input to the serial port, UDP packets are sent using the preset IP address and

the socket number of the server.

Interface RS422

Serial Port 1,2 hardwired to RS232 so that this category cannot be selected.

Serial Port 3, 4 can be used RS422 or RS485 (Echo, No Echo) by selecting.

In Eddy-CPU, this can be selected by Dip Switch S8, S9 on Eddy-DK board so that this category

cannot be selected.

(option: RS422, RS485(Echo), RS485(No Echo))

Local Socket

Port

4001

Set the socket number for the port. TCP server and UDP server operation mode makes use of

this port for awaiting network socket connections.

Port Alias Port1 Port alias name for convenience. 16 Characters at maximum.
