• Public IP address.
A public IP address is an IP address that can be used anywhere, including on the
internet. The ranges available include everything from 1.1.1.1 to
223.255.255.255, with the exception of 127.x.y.z and those ranges defined as
private IP addresses, above.
• Pulse width modulator.
Pulse width modulator (PMW). A specialized timer that generates a pulse-train,
whose duty cycle is proportional to the intensity of a connected light (such as, a
ring LED).
• Pulse.
A pulse is a temporary change of a signal's state (for example, from OFF to ON),
typically reoccurring at regular intervals.
• Static IP address.
A static IP address is an IP address that does not change. Unlike a dynamic
allocation, a static allocation does not expire. Your Matrox GatorEye and your
computer can both be assigned static IP addresses manually or through a fixed IP
address returned by a DHCP server request.
• Subnet.
A subnet is the portion of an IP address that must be common between computers
for direct communication to occur. Special hardware (routers) is required for
computers on different subnets to communicate. The subnet is defined by an IP
address and a subnet mask. IP addresses and subnet masks are written in dotted
decimal notation (each group of numbers is separated by a period).
To determine your subnet address, examine your subnet mask. For example, if an
IP address of 169.254.17.26 has a subnet mask of 255.255.0.0, the subnet address
would be 169.254. If an IP address of 192.168.12.34 has a subnet mask of
255.255.255.0, the subnet address would be 192.168.12.
