Single Board Computer Advme1420A
32-channel/32-channel High Speed Digital Input Output VME board
Features
-32-point Digital I/O board
-32-point input is divided between four I/O channels with a common I/O for every eight points
-Each I/O channel has an independent common I/O for digital signals using different power supplies
-Can be used as an upwardly-compatible replacement for Advme1420
-Photo-coupler isolation between input channels and between input channel and system
-Interrupt can be issued to one of the VME interrupt request lines
-IRQ1 to IRQ7
-Use switch on the panel to select and display on monitor for every eight I/O points
-Device driver for VxWorks (option)
