General Features
The AVME946X Digital Input/Output (I/O) Board provides a means for interfacing various discrete devices to a
VMEbus based computer. Interfacing is accomplished by 32 or 64 general purpose I/O points which under
software control may be individually programmed to be inputs or outputs.
1.2 FEATURES OF THE AVME 946X
•
32 or 64 programmable I/O points (lines) configured as 4 or 8 - 8 bit ports or 2 or 4 - 16 bit ports all with
inverted logic.
•
Can read the state of points configured as outputs.
•
Outputs sink up to 100 mA, from an external 5V supply.
•
Built in protection diodes for driving relay coils.
•
Input hysteresis.
•
Compatible with industry standard solid state relays and termination panels, PB16 and PB32. AVME 9460
and 9462 provide direct connection to the PB16 termination panel, no adapter boards necessary. Optional
universal termination panel available for use with contact closures, relays, incandescent lamps.
•
TTL and CMOS compatible.
•
Byte or word data transfers.
•
Board identification PROM.
•
Pass/Fail Status indicators on the front panel.
•
I/O accessible through the front panel or out of the back of the card cage.
1.3 FEATURES OF THE AVME 941X
The AVME941X Digital Output Board provides a means for interfacing various discrete devices to a VMEbus
based computer. Interfacing is accomplished by 32 or 64 output points.
The AVME 941X Digital Output Board features:
•
32 or 64 programmable Output points (lines) configured as 4 or 8 - 8 bit ports or 2 or 4 - 16 bit ports all with
inverted logic.
•
Outputs sink up to 100 mA, from up to a 30V external source.
•
Built in protection diodes for driving relay coils.
