ABOUT YOUR MT112-100 2
MT112-100
Universal IO Control Card
The MT112-100 has 24 Input/Output ports. These
ports are jumper configurable and each may be
configured as either an input or an output port. As
outputs, these IO ports may be used to control
external controls and devices. As inputs, these
ports can trigger events and control other cards in
the Multi-Tasker™ enclosure.
As an Input port, an external contact closure to
ground activates the port. A subroutine may be
used to execute any number of desired commands.
Each port may be assigned one subroutine to be
performed when a low to high transition occurs and
another when a high to low transition occurs.
As an Output, the port generates a TTL level, 0 to
5 volts, output with a 24mA drive capacity. These
outputs may be used to drive external LED's or
other circuitry.
The I/O ports may also be configured to work in
pairs. The first member of the pair is used as an
input to sense an external key or switch. The
second member of the pair controls an external
LED. Special control commands are available
which allow subroutines to be assigned to actions
when the key is pressed. Additionally, different
subroutines may be assigned to perform different
tasks depending on whether or not the LED is on or
off when the key is pressed.
