Functional Description
Note:
Some computers can accept as many as three DAS-1800
Series boards.
●
Assign one interrupt level to be shared by all boards.
If a DAS-1800 Series board is sharing an interrupt level with one or more
other DAS-1800 Series boards and requests an interrupt, the DriverLINX
software determines the source of the request by scanning each board
until the interrupt request flag is located. DriverLINX then signals the
computer to respond accordingly.
Power
DAS-1800HC Series boards use the +5V and the +12V provided by your
computer. An onboard DC/DC converter develops ±15V at a maximum
current draw of 30mA for external use. In addition to the ±15V, the
DAS-1800HC Series boards supply the +5V from the computer to a pin
on the main I/O connector.
