PC2-Comp Express
RS-232
A standard serial communication port.
RS-422
RS-422 is a serial communications standard that provides a much longer transmission
distance (but fewer signal lines) than to RS-232.
Scatter Gather
Host system memory allocated for frame buffers is virtually contiguous but physically
scattered throughout all available memory.
Trigger
A mechanism that initiates an action when an event occurs such as synchronizing an image
acquisition to an external event. A trigger generally causes a program routine to be executed
such as the resetting of camera exposure and/or the firing of a strobe light.
TTL
Transistor-Transistor Logic. Acceptable TTL gate input signal voltage levels are:
LOW: lower than 0.8V
HIGH: higher than 2.0V
Any voltage between 0.8V and 2.0V is uncertain and will not be reliably interpreted by the
TTL device.
UART
A UART (Universal Asynchronous Receiver/Transmitter) is the microchip with programming
that controls an interface to its attached serial devices.
