3.2 Host Mode Configuration
Host mode represents the operating session mode of the Rhio10. Several host modes are
available for the data communication between the I/O device and remote hosts. Since TCP is
connection-oriented protocol, server, client, server/client modes are provided. Table 3-3 shows
the brief description of the host modes. A factory default host mode is TCP Server.
Note:
In order to use Rhio Manager, users have to set Host Mode as TCP Server mode.
Table 3-3 The Rhio10 TCP/IP session modes
Mode Description
TCP Server Select this mode, when users want the Rhio10 to operate as a TCP server. The
Rhio10 stands by until there is any TCP connection request. If TCP connection is
not already established at that time, the Rhio10 accepts the request and the
session is established. If it is established, then the system may receive the I/O
control command and perform the corresponding operation. Since the Rhio10
supports only one TCP session, the additional TCP connection request will be
rejected if already established. This mode is useful when users want to control I/O at
any time.
TCP Client Select this mode, when users want the Rhio10 to operate as a TCP client. Select
this mode, when users want the Rhio10 to operate as a TCP client. When the I/O
port status f the Rhio10 is changed or pre-defined timer is expired, the Rhio10
tries to establish a TCP connection to a remote server through its TCP port. If a
