Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function.

Programmable automation controller (PAC) modules are add-on devices that perform a specific control function in PAC systems.

Serial communication adapters provide one or more serial ports to a host computer.

Network gateways interconnect networks with different, incompatible communication protocols.

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control.

Packet generators create a discrete chunk of communication in a pre-defined format.

Network test equipment is used to test, probe, and analyze telecommunication, network and telephone systems.
