z
Operation Mode (Default: COM(Win200x/XP))
Select the operation protocol, which the serial port would use.
J
COM(Win200x/XP)
Use the serial port of Eddy as the COM ports of Windows 2000/XP/2003 operated PC.
(Both the data and the signal line information of the serial port can be controlled.)
J
COM(Win98/ME)

data and the signal line information of the serial port can be controlled.)
J
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.
J
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.
J
TCP Multi-Server
Eddy works as a server, accepting up to 5 simultaneous connections from socket clients.
Data transmitted from Eddy is broadcast to each socket client.
J
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.
J
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.
