	UART
	Matrox Meteor-II /Digital features a Universal Asynchronous
	Receiver/Transmitter (UART) that provides an RS-232 serial
	interface. For example, this allows remote camera
	configuration, a motion control unit, or of a program logic
	controller (PLC). The UART is programmed using the MIL-Lite
	function, MdigControl() with the M_UART... control types.
	Lookup table (LUT)
	The Matrox Meteor-II /Digital board has four 256x8-bit
	programmable lookup tables. The LUTs on Matrox Meteor-II
	/Digital can be operated as four 8-bit lookup tables, two 10-bit
	lookup tables, or two 12-bit lookup tables.
	PSG
	The Programmable Synchronization Generator (PSG) is
	responsible for managing all timing and synchronization
	signals.
	Control signals
	The following is a short description of the control signals on the
	Matrox Meteor-II /Digital interface. Note that depending on the
	version of your board, the signals will be in RS-422 or LVDS
	format. It is indicated when other signals such as TTL signals
	are also supported.
	The interface can receive and/or supply the HSYNC and
Synchronization
	VSYNC signals. The VIA receives the synchronization signals
	from the PSG or from an external source.
	The VIA also receives a VALID signal that can either be
Valid
	generated by the PSG or an external source. When received by
	PSG, it can indicate valid pixels on a line by line basis. When
	received from an external source, it can indicate valid pixels on
	a pixel by pixel basis.
	The interface of the Matrox Meteor-II /Digital board can receive
Clock
	and supply a clock, simultaneously.
