Timeout Value
The connection to the network is automatically disconnected if there is no access to the AQ1200 for
the specified time.
Range: 1 to 3600 s or Infinite
The AQ1200 will not time out if you set the timeout value to Infinite. If the AQ1200 is connected to a
network and the connection between the AQ1200 and another device is broken abnormally due to an
external cause, the AQ1200 will remain connected to the network until the power is turned off. To avoid
this kind of situation, we recommend that you set a finite timeout value.
TCP/IP
DHCP
If you are connecting the AQ1200 to a network with a DHCP server and you want to use the server,
set DHCP to “On.”
On
The IP address, subnet mask, and gateway information is assigned automatically.
Off
You must enter the IP address, netmask, and gateway information.
• Ask your network administrator whether or not DHCP is available.
• When DHCP is set to On, the information can change whenever you restart the AQ1200 or
enable or disable the network setup as described in the previous section. Check the information
when you access the AQ1200 from a PC.
IP Address
You can set the IP address assigned to the AQ1200. The IP address is an ID that is assigned
to each device on a network such as the Internet or an intranet. Obtain an IP address from your
network administrator. In a network that supports DHCP, this parameter is set automatically when
DHCP is set to On.
Subnet Mask
You can set the mask value used to determine the subnet network address from the IP address.
Networks such as the Internet are often divided up into smaller networks called subnetworks. The
subnet mask is a value that specifies the number of bits of the IP address that are used to identify
the network address. Consult your network administrator for the subnet mask value. In a network
that supports DHCP, this parameter is set automatically when DHCP is set to On.
Gateway
You can set the IP address of the default gateway (which is a gateway used to communicate with
other networks). The default gateway handles data exchange between multiple networks so that
data transmission proceeds smoothly. Consult your network administrator for the default gateway
value. In a network that supports DHCP, this parameter is set automatically when DHCP is set to
On.
