Setting for communication between the recorder and PC

Following settings are required for communication between the recorder and PC. This section describes an
example of networking using a switching hub as illustrated in 4.1.2.
4.2.1

Setting the IP address of the recorder

For communication between the PC and each recorder, their network addresses must be identical. A network
address is a component of an IP address, starting from the head of the IP address. A subnet mask determines
where the network address ends in the IP address.
[Example]
IP address
: 192.168.000.100
Subnet mask : 255.255.255.000
In this example, the first block containing the numbers "192.168.000" in the IP address is recognized as a network
address. The last "100" is a host address, which represents respective terminal in the network. When connecting a
PC and more than one recorder in the same network, be careful not to use duplicate host addresses.
In this example, the IP addresses of the recorders are set as follows:
Recorder A
: 192.168.0.100 (Subnet mask 255.255.255.0)
Recorder B
: 192.168.0.101 (Subnet mask 255.255.255.0)
Recorder C
: 192.168.0.102 (Subnet mask 255.255.255.0)
For the procedure to set the IP addresses of the recorders, see the operation manual of each recorder.
4.2.2

Setting the port number of the recorder

For communication between the recorders and PC, it is required to set a port number. You can find this port
number by [USER ACCESS] port in the Network menu of the recorder. The default port number shown by [USER
ACCESS] port of the recorder is 53705. You don't need to change this number in normal use. Change this number
when it is necessary to set different port numbers in an NAPT configuration using an ADSL router.
4.2.3

Setting the IP address of the PC

The procedure to set the IP address of the PC depends on the type of operation system you use. This section
describes the procedure to set the IP address for Windows XP. As described in 4.2.1 above, the network address
of the PC should be identical to that of the recorder. Be sure to use the same network address as that of the
recorder when setting the IP address of the PC.
4.2.4

Checking communication using a ping command

After setting the IP addresses and port numbers, check whether the communication is carried out successfully
using a ping command. Ping command is a command to check whether the terminals can communicate each
other over the network. Most Windows operating systems are equipped with this command.
In the case of an NAPT configuration using an ADSL router as illustrated in 4.1.3, most ADSL routers don't
respond to a ping command sent via the Internet unless those routers have special settings for it.
[Ping test method]
Select [Start] > [Accessory] > [Command Prompt]. At the command prompt, enter >ping 192.168.0.100. (In the
actual test, use the IP address of the recorder to be tested and enter a blank at the head of the IP address.)
When the communication is carried out properly, the following message is displayed.
Pinging 192.168.0.100 with 32 bytes of data:
Reply from 192.168.0.100: bytes=32 time<10ms TTL=255
Reply from 192.168.0.100: bytes=32 time<10ms TTL=255
Reply from 192.168.0.100: bytes=32 time<10ms TTL=255
Reply from 192.168.0.100: bytes=32 time<10ms TTL=255
If the following timeout message is displayed, the recorder and PC are not connected correctly by the LAN cables.
In this case, check the cable connections.
Pinging 192.168.0.100 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
In particular, when the following message is displayed, the network address of the recorder is not identical to that
of the PC or the default gateway of the PC has been set incorrectly. Check the settings.
Pinging 192.168.0.100 with 32 bytes of data:
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
