Driver Block Parameters

Channel vector -- Enter numbers between 1 and 8 to select the digital output lines to drive. This driver allows the selection of up to 8 individual digital output lines in any order. The number of elements defines the number of digital lines used.

For example, to use all of the digital inputs enter

• [1,2,3,4,5,6,7,8]
  

Number the lines beginning with 1 even though the board manufacturer starts numbering lines with 0.

Port -- From the Port list, choose either A, B, or C. The Port parameter defines which port is used for this driver block. Each port has a maximum of 8 digital outputs. In each case, one block is needed for each port.

Reset vector -- The reset vector controls the behavior of the channel at model termination. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that setting is used for all channels. If you specify a value of 1, the corresponding channel is reset to the value specified in the initial value vector. If you specify a value of 0, the channel remains at the last value attained while the model was running.

Initial value vector -- The initial value vector contains the initial values (0 or 1) of the output channels. Enter a scalar or a vector that is the same length as the channel vector. If you enter a scalar, that value is used for all channels. The channels are set to these initial values between the time the model is downloaded and the time it is started.

Sample time -- Enter the base sample time or a multiple of the base sample time.

Base address -- Enter the base address of the board in hexadecimal (such as 0x300) as selected with the hardware jumpers on the board.

Note    Please consult the appropriate Diamond Ruby-MM hardware manuals for more information on jumper settings and I/O connections.
