Eddy User's Guide

Default

Descriptions

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))
