Server without connection.
IO Extender Master
, uses Master Server protocol,
passively waits for IO Extender Slave
IO Extender Slave
, uses Slave Client protocol,
actively connects to IO Extender Master
Destination IP address/

modes:
Enter the Server IP address and port number when
set in TCP client or UDP client mode.

This section will introduce some examples to control the DIO lines of
this
Adapter
. We are using a Terminal Emulation Program (such as
HyperTerm or TeraTerm) to send control strings over the TCP/IP socket
port.
HyperTerm is a Windows based utility for Windows XP or earlier version.
However, it is not bundled in Vista or later Windows version.
As shown in the HyperTerm examples, the application software can
read or write the string (in ASCII code format) on the TCP/IP socket
port to check or change the
Adapter
’s state.
