Default
Descriptions
Operation
Mode
TCP
Server
Select the operation protocol, which the serial port would use.
Disable
Do not use this port.
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. Server IP and port
number can be set in [Remote IP/Port].
User Application
An executable file build by a user can be uploaded.
Interface
RS232
The serial port 1 and 2 are fixed to RS232 so these ports cannot be selected.
By selecting RS422 or RS485 (Echo, Non-echo) serial port 3 and 4 can be
used.
In Eddy-CPU, this can be selected by the dip switch S8 and S9 on Eddy-
DK board, therefore this category cannot be selected.
(option: RS422, RS485(Echo), RS485(Non-echo))
Local Socket
Port
4001
Set the socket number for the port. TCP server and UDP server operation
mode make use of this port for awaiting network socket connections.
