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

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.

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.

Synchronization
The interface can receive and/or supply the HSYNC and
VSYNC signals. The VIA receives the synchronization signals
from the PSG or from an external source.

Valid
The VIA also receives a VALID signal that can either be
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.
