uSwitch and uSwitchPro Installation and Operating Manual Page 20
Host Name
This configurable field represents a user chosen name for your uSwitch. It will be used when reporting information from
this device and in any status logs. It is a virtual name for the current uSwitch device.
Enable DHCP
This check box should be selected when the user chooses to have a DHCP server automatically assign IPV4 addresses
to the uSwitch. DHCP is not recommended as DHCP assigned addresses are subject to change making it difficult to
permanently access a uSwitch whose address could change at random points in time.
IP Address
This specifies the unique IPV4 address of the uSwitch on the LAN. (Each uSwitch is factory configured with the default
static IPV4 address of 192.168.1.199). This static LAN address should be modified to be consistent with the LAN’s
subnet on which it is to be installed.When using multiple uSwitch devices on the same LAN each uSwitch must have a
unique IPV4 address.
Gateway
This specifies the IP address of the gateway (typically router/cell modem) which is responsible for creating the LAN and
connecting to other networks and or the WEB. If unknown, the Gateway address can be obtained from the network
administrator. The Gateway is the LAN address of the device that routes the internal LAN to an outside network (WAN) or
other networks. The factory default gateway setting for the uSwitch is 192.168.1.1. This must be the assigned address of
the device that routes the network on which the uSwitch is connected for uSwitch features to function correctly. For
instance, pinging devices that are outside the local are network when Auto Reboot mode is enabled will not work if the
correct Gateway address is not assigned..
Subnet Mask
The subnet mask identifies a specific LAN’s private addressing scheme on a TCP IPV4 network. This can typically be
obtained from the network administrator. The uSwitch default subnet mask is set to 255.255.255.0. Each of these four,
three-digit fields represents an IPV4 address field. Each of these fields represents a byte worth of addressing (1-255).
Any bit positions in the address with a value of zero are accessible on the local subnet. Any bit positions with a value of 1
are fixed (unchangeable) on the local subnet. In the subnet mask, 255.255.255.0, the first three IP byte address fields
are fixed and the last byte field may vary from 1 to 255 (a value of 255 is equivalent to 11111111 in binary).
HTTP Port
This specifies the HTTP port (for typical WEB access) used for outside communications to the uSwitch. By default, this
port is set to 80 (standard access port for HTTP devices). A unique port is required for each uSwitch or other such device
that is going to be accessed using a port address from outside the local network. In this case, each uSwitch device on the
same local area network would be assigned a different port (for example 41, 42, 43, etc). With unique ports assigned to a
uSwitch, a router can forward all outside communication for a given device directly to a specific uSwitch without the
outside network having any internal knowledge of the addressing scheme on the LAN beyond the address of the gateway
to the LAN and the virtual port number (private IPV4 addresses are not accessible to the outside world/cloud). Each
uSwitch is then accessed from the cloud on its private network by entering the routable/resolvable IP address of the
gateway and the specific port assigned to the uSwitch™. Any port (besides port 80) assigned to a uSwitch™ requires all
outside communications to that uSwitch to reference it via its assigned port. For instance,
www.videogenix.com:42
(for a
device on port 42) or www.MyHomeRouter:41.
TCP Port
This specifies the TCP port for any internal or external TCP commands to the uSwitch used for outside communications to
the uSwitch. By default, this port is set to 9760 (standard port for TCP). This port does not need to be changed unless
your remote device specifies a port other than 9760 to this device IP address or If multiple uSwitches on the same subnet
are to be accessed via TCP from outside the network using only port numbers. With unique ports assigned to a uSwitch,
a router can forward all outside communication for a given device directly to a specific uSwitch without the outside
network having any internal knowledge of the addressing scheme on the LAN beyond the address of the gateway to the
LAN and the virtual port number (private IPV4 addresses are not accessible to the outside world/cloud). Each uSwitch is
then accessed from the cloud on its private network by entering the routable/resolvable IP address of the gateway and the
specific port assigned to the uSwitch™.
