DNS
It is difficult to remember an IP address since it is simply a string of
numbers. However, it is easier to remember if it can be specified as a name.
When the network includes a server that can search for IP addresses from
names on the network, you can specify devices by name instead of using the
IP address.
This service is provided by both DNS and WINS servers; however, the 8855
only supports DNS.
Further, the 8855 does not dynamically register names and IP addresses with
the DNS.
Enabling DNS allows a connected remote device to be specified by name.
When DHCP is enabled and DNS information can be acquired from the
DHCP server, the setting obtained from DHCP is given priority.
Gateway ON/OFF, IP Address
When the communicating device (PC) is on the network connected to this
device as well as on different network, turn the Gateway setting ON, and
specify the IP address of the device that is the gateway. Generally, if a PC is
on the same network, you can make this setting the same as the default
gateway address of the PC.
No default gateway is needed when the device and the PC are connected 1-
to-1 (peer-to-peer), or when connected to the same hub, therefore turn this
setting OFF.
When DNS is effective and the set IP address is other than 0.0.0.0, the set IP
address is used.
If the IP address is set to 0.0.0.0, DNS is used to search for the IP address.
For example, names are set in the following format: gateway.hioki.co.jp In
the case of this example, if ".hioki.co.jp" is omitted, DNS may not be able to
identify the IP address.
When DHCP is effective and Gateway information can be acquired from the
DHCP server, the setting obtained from DHCP is given priority.
TCP/IP Port Number
This device uses TCP/IP protocols for communications. TCP/IP enables
multiple connections of each type to communicate and classifies them by
port number. This device normally uses numbers from 8800 to 8809.
8800 (This device is the server): Used in remote operation applications on
the 9333
8801 (This device is a client): Used in data collection applications on the
9333
8802 (This device is the server): For the control by the communication
command
8803 to 8809 are reserved.
Normally, these do not need to be changed. However, if there is a port that
cannot be used because for security reasons or because it is being used on
the PC communicating with this device, change this port. Set the first 3
digits. The last digit, ranging between 0 and 9, is either used or reserved for
use by the device.
