address. Once users click [Quick Connect] button, then Rhio10 detected is shown on the Probe
screen as a tree structure form. If users click the one, then they will be asked to enter the ID
and Password. The Rhio10 parameters are displayed on the Get/Set screen with correct ID and
password (Factory default ID:PASSWORD is admin : admin.)
Figure 2.8 Quick connect dialog box

16
Probe
Users may probe the Rhio10 on the network. If users perform [Probe] command, then the
Rhio10 detected will be shown on the Probe screen. If users select the one in the Probe screen,
then they are asked to enter ID and Password. Users are able to configure the Rhio10’s
parameters within the Get/Set screen.
Set
After users complete the configuration, they have to click [Set] button to reflect the changes.
Once it is done, the changes will be stored on to the flash memory and the system will be
rebooted.
Reboot
Users may reboot the Rhio10 by using the botton. In this case, the TCP connection is
disconnected, whereas the I/O management status is still maintained.
I/O PORT CONTROL
Users may monitor, control and configure the Rhio10’s I/O ports by clicking [I/O PORT
CONTROL] button.

3. System Configuration and Administration
3.1 Network Configuration
A valid IP address of the Rhio10 needs to be assigned before it starts to work in the user's
network environment. A network system administrator may provide the user with this IP
address setting information for the network. The IP address must be unique within the network.
Otherwise, the Rhio10 will not have a valid connection to the network.
Users can choose the desired IP mode out of the three IP operating modes, i.e., Static IP,
DHCP and PPPoE. Thefactory default IP mode is DHCP mode. Table 3-1 shows the parameter
items for IP configuration.
Table 3-1 IP Configuration Parameter
IP address
Subnet mask
Static IP
Default gateway
DHCP No parameters required
PPPoE usernamePPPoE
PPPoE password
Figure 3-1. Rhio10 Network Configuration screen

18
The factory default configuration of IP mode is DHCP mode. In order to detect the Rhio10 for
the first time, users have to perform [Probe] function by using Rhio Manager. If there is a DHCP
server on the users’ environment, then the IP address assigned by the DHCP server is
displayed. Otherwise, it will display the IP address as 0.0.0.0. In this case, users have to change
the IP mode as Static IP mode, and then enter the proper IP address for their environment.
After the Rhio10 is displayed on the [Probe screen], click the unit that users want to connect.
Figure 3-2 Password Enter Dialog box
During the configuration, users may change the parameters as they want. The parameter value
will be maintained as RED color until the changes are reflected by using [Set] button.
Figure 3-3 Network Configuration Screen example

19
Users will have to click [Set] button in order to reflect the parameter changes. Once [Set]
operation is done, Rhio10 automatically store the changes and then reboot the system. Be sure
to perform [Probe] function to check whether the changes are made correctly after [Set]
operation.
Figure 3-4 Network Configuration screen
3.1.1 Static IP
In the Static IP mode, users have to manually specify all the parameters such as IP addresses
of the Rhio10, valid subnet mask and the default gateway IP address.
IP address is an identification number assigned to a computer as a permanent address on the
network. Computers use IP addresses to identify and talk to each other on the network. Choose
the proper IP address which is unique and valid on the network environment.
A subnet represents all the network hosts at one geographic location, in one building, or on the
same local area network. When there is any outgoing packet over the network, the Rhio10 will
check whether the desired TCP/IP host specified in the packet is on the local network segment

20
with the help of the subnet mask. If the address is proven to be on the same network segment
as the Rhio10, the connection is established directly from the Rhio10. Otherwise, the
connection is established through the given default gateway.
Agateway is a network point that acts as an entrance to another network. Usually, the
computers that control traffic within the network or at the local Internet service provider are
gateway nodes. The Rhio10 needs to know the IP address of the default gateway computer in
order to communicate with the hosts outside the local network environment. For correct
information on the gateway IP address, please refer to the network administrator.
3.1.2 DHCP
Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network
administrators manage and automate the assignment of IP addresses centrally in an
organization's network. DHCP lets a network administrator supervise and distribute IP
addresses from a central point and automatically send a new IP address when a computer is
plugged into a different place in the network.
As described in the section 3.1, the IP address must be entered manually at each computer in
Static IP mode and, if computers move to another location in another part of the network, a new
IP address must be entered. Meanwhile, all the parameters including the IP address, subnet
mask, gateway, DNS servers will be automatically configured when the IP address is assigned
in DHCP mode. DHCP uses the concept of a "lease" or amount of time for which a given IP
address will be valid for a computer. All the parameters required to assign an IP address are
configured on DHCP server side, and each DHCP client computer receives this information
when the IP address is provided at its boot-up.
To obtain an IP address, the Rhio10 sends a corresponding DHCP request as a broadcast over
the network after each reset. The reply generated by the DHCP server contains the IP address
as well as the subnet mask, gateway address, DNS servers and the lease time. The Rhio10
immediately places this information in its non-volatile memory. If the operating time reaches the
lease time, the Rhio10 will request the DHCP server for renewal of its lease time. If the DHCP
server approves extending the lease, the Rhio10 can continue to work with the current IP
address. Otherwise, the Rhio10 will start the procedure to request a new IP address to the
DHCP server.
A DHCP sever assigns IP addresses dynamically from an IP address pool, which is managed
by the network administrator. This means DHCP client, i.e. the Rhio10, receives a different IP
address each timeit boots up. To prevent the case that users do not know the IP address of the
