Descriptions
Baud Rate
9600 bps
Set communication speed.
(Options: 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200, 230400, 460800, 921600 bps)
Data Bits
8
Set the number of bits in each character size.
(Options: 5, 6, 7, 8)
Stop Bits
1
Set the number of stop bits.
(Options: 1, 2)
Parity
None
Set parity bit check scheme.
(Options: None, Odd, Even)
Flow
Control
None
Set the flow control scheme.
(Options: None, Xon/Xoff, RTS/CTS)
Device Type
DataOnly
Set the signal line checking method for the device to be connected to the
given serial port.
If the mode is set to Data Only, only TxD, RxD, and GND signal lines are
used in inter-device communication. If the mode is set to Modem Signals,
all modem signals except RI (Ring Indicator) are asserted, tested, and used
in communication.
(Options: Data Only, Modem Signals)
Remote IP
Address /
Port
0.0.0.0 /
4000
While in TCP Client or UDP Client mode, set the target IP address and the
port number.
Keepalive
Check
Time
0
After a certain amount of time passes without any communication after the
socket connection between the given serial port and the server are
established, automatically disconnect the socket connection. (Valid from 0
to 32767 sec. When set to 0, it is disabled.)
For example, if the operation mode is set to TCP Server and Alive Check
Time is configured to 10, TCP Server will listen for the client’s connection
and eventually establish a connection. Since the check time is 10 seconds,
the server will wait for 10 seconds until the client connected to it sends any
packet. If there is no data for 10 seconds, server will quit the connection
and return to the listening state. This option is helpful in preventing
communication obstacles that occur when either Eddy or the client quits
unexpectedly (i.e. Sudden black out, reboot, LAN cable cut, etc.). In these
cases, the other part of communication might not recognize the failure of
its partner. Such misunderstanding can cause communication errors.
If the value is set to 0, this function is disabled. Once connected socket
will be retained until explicitly disconnected.
(Only applies to TCP Client, TCP Server, TCP Broadcast, and TCP
Multiplex operation modes.)
Latency
Time
0
This needs to be set when consecutive data from the given serial port needs
to be transmitted to socket at once.
For example, if 100 bytes of character string are to be transmitted from the
serial device to a server through Eddy, bypass is set to 0 for the latency
time. Although it provides immediate sending through Eddy, the server
could be received a lot parts of divided packets.
If the latency time is not 0, Eddy will wait for the time and check new
data. If there is new data, Eddy repeatedly wait for the time. Otherwise,
Eddy will transfer the buffered data, but it could not run in real time.
