Matrox Meteor-II /Digital grab section
UART and RS-232 serial port
Matrox Meteor-II /Digital for PCI features a Universal
Asynchronous Receiver/Transmitter (UART) that provides an
RS-232 serial interface. For example, this allows you to
remotely control a camera or a motion control unit, or to
communicate with a program logic controller (PLC). The UART
is programmed using the MIL-Lite function, MdigControl()
with the
... control types.
M_UART
❖
The UART is not supported on the PC/104-Plus form factor.
Lookup tables
The Matrox Meteor-II /Digital board has four 256 x 8-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
Matrox Meteor-II /Digital contains a Programmable
Synchronization Generator (PSG), which 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
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
generated by the PSG or an external source. When received by
the 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.
