DIO-100
AniLink
Digital I/O Card
The
DIO-100 is an eight-bit input or eight-bit output TTL-level digital
Input/Output device for use on the AniLink bus. The DIO-100 can
also be used as an interface to many parallel communication devices
such as absolute encoders, PLC's or custom control systems. Each
unit takes up 1 AniLink port address (8 max). Each Input/Output
can source as much as 2 mA or sink up to 10 mA. They reliably switch
an electronic relay or SRC, but can not drive a mechanical relay
directly. All signals must be inputs or all outputs at any one time.
Data is read from the DIO-100 eight bits at a time and arrives at
the controller as an integer. This integer can then be parsed or
used in mathematical equations allowing the controller to respond
to conditions outside the system. A data strobe signal, a read/write
flag and two address outputs are provided to allow a convenient
data transfer protocol to external equipment. These signals can
be ignored in applications using only simple Input/Output. The DIO-100
is plug-in compatible with the SmartMotor. As many as eight DIO-100
modules can be uniquely addressed on a single AniLink bus. The
AniLink bus and DIO cards employ I2C technology. The chips are
readily available and schematics may be obtained from Animatics
for your own custom use for very unique or price sensitive applications.
The SmartMotor is always the master over RC communications.
