"The
external device may be any suitable electronic device such as a portable media player, personal data assistant or electronic lock that may be used to access a door, car, house or other physical area."
The CPCI-560 configurable digital input/ output board uses the 3U CPCI form factor and is intended for process control applications, instrumentation needing logic-level lines, and
external device or apparatus status and control of special text fixtures.
This eliminates the need for
external device drivers.
This is accomplished by disabling the functionality of a user design within the FPGA until handshaking tokens are passed to the FPGA from a secure
external device. The secure
external device generates continuous handshaking tokens to the FPGA, ensuring continuous operation.
Acting as an automated attendant to "watch" the video when nobody is available, it alerts the user on an
external device when an event is detected.
This
external device increases system cost and also forces the entire microcontroller to run at a higher voltage, which wastes valuable battery power.
Voice capabilities are built directly into the SuD2000, eliminating the need for a voice gateway or any
external device.--Net to Net Technologies
The Monitouch V7 can be used in conjunction with a number of devices such as a bar code reader as it has several
external device drivers included with it.
