MESA 7I80DB is a low cost, general purpose, FPGA based programmable I/O
card with 100 BaseT Ethernet host connection. The 7I80DB that uses
standard parallel port pinouts and connectors for compatibilty with most
parallel port interfaced motion control /
CNC breakout cards/ multi axis step motor drives, allowing a motion
control performance boost while retaining a reliable real time Ethernet
interface. Unlike the parallel port that the 7I80DB replaces, each I/O
bit has individually programmable direction and function. The 7I80DB has
a simplified UDP host data transfer system that allows operation in
real time if required and compability with standard networks for
non-real time applications. Dual FPGA configuration EEPROMs allow simple
recovery from programming mistakes. The 7I80DB provides 68 I/O bits (17
per connector) All I/O bits are 5V tolerant and have pullup resistors. A
power source option allows the 7I80DB to supply 5V power to breakout
boards if desired. This 5V power is protected by a PTC. Firmware modules
are provided for hardware step generation, quadrature encoder
counting, PWM generation, digital I/O, Smart Serial remote I/O, BISS,
SSI, SPI, UART interfaces and more. Configurations are available that
are compatible with common breakout cards and multi axis step motor
drives like the Gecko G540. All motion control firmware is open source
and easily modified to support new functions or different mixes of
There are currently
six 7I80DB compatible breakout cards available from Mesa, the 7I74
through 7I78 and 7I85. The 7I76 is a step/dir oriented breakout with 5
axis of buffered step/dir outputs, one spindle encoder input, one
isolated 0-10V analog spindle speed plus isolated direction and enable
outputs, one RS-422 expansion port, 32 isolated 5-32V inputs and 16
isolated 5-32V 300 mA outputs. The 7I77 is a analog servo interface with
6 encoder inputs, 6 analog +-10V outputs, one RS-422 expansion port, 32
isolated 5-32V inputs, and 16 isolated 5-32V 300 mA outputs. The7I80DB
supports four breakout cards so for example a 20 Axis step/dir
configuration or 24 axis analog servo configuration is possible with a
single 7I80DB and four Mesa breakout cards.
