Diamond Ruby-MM Digital Output - Ruby-MM Digital Output block

Library

xPC Target Library for Diamond

Scaling Input to Output

Hardware Output	Block Input Data Type	Scaling
TTL	Double	< 0.5 = TTL low ≥ 0.5 = TTL high

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. One block is required for each port used.

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 Diamond Ruby-MM hardware manuals for more information on jumper settings and I/O connections.
