recommended for most installations). If DHCP is set to
Yes
, the Network page must be submitted and
the XW-112 must be rebooted before an IP address will be assigned. Once the XW-112 is assigned an
IP address by the DHCP, the new IP address can be found through the clients list kept by the DHCP
server. For most instances, this is found on the local gateway or router. Alternatively, the device will
broadcast its information via mDNS.
Brief Notes About DHCP:
All devices on an IP network require an IP address. This is a unique address
that identifies each device on the network. DHCP (Dynamic Host Control Protocol) is a mechanism that
automatically assigns an IP address to a computer (or other devices) when it is connected to a network.
This eliminates the need to manually enter the IP address. When a computer is connected to the
network, another device on the network called a DHCP server detects the presence of the computer and
dynamically assigns the IP address to that computer. On many small networks, the DHCP server is built
into the router.
DHCP works well for "client" devices such as computers, but is not ideal for servers. This is because
servers usually don't initiate communications with other devices, but rather they wait for a request from
"clients." To make this request, the client must know the IP address of the server. If a server gets its IP
address dynamically, the IP address may not always be the same so client devices may not be able to
find the server. For this reason, servers usually use an IP address that is fixed and does not change.
The XW-112 is a server and manual IP address assignment is usually recommended.
IP Address
Enter the IP address for the XW-112 in this field. The IP address is specific to the network where the
XW-112 will be installed and is obtained from the network administrator. The default setting for this field
is 192.168.1.2
Subnet Mask
The subnet mask defines the size of the local network. This can be obtained from the network
administrator. For additional information about sub-netting and IP networking, many tutorials are
available on the Internet. The default setting for this field is 255.255.255.0
Gateway
This specifies the IP address of the gateway router. This can be obtained from the network administrator.
The default setting for this field is 192.168.1.1
DNS Server
The IP address of the DNS server is specified here. When DNS services are required, this is the
address that will be used. The default setting for this field is 192.168.1.1. An alternate DNS server is not
supported.
HTTP SERVER
Since the HTTP server is always enabled, the XW-112's setup and control pages can be accessed using
a web browser or the CBW Mobile app and you can view the current water alarm status.
The TCP port used for HTTP communications with the XW-112 can be customized here. The default
setting for this field is 80, which is the standard HTTP port. It is recommended that the port be left
unchanged unless the user has an understanding of TCP/IP and ports.
