Block Parameters

This board has 2 analog outputs (D/A) with a fixed range of -10 to +10 volts.

Channel vector

Enter 1 or 2 to select the digital output lines used with this port. This driver allows the selection of individual digital input lines in any order. The number of elements defines the number of digital lines used.

For example, to use all of the digital outputs for one port, enter

[1,2]

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

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 voltage values for the output channels. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is the initial value for all channels. The channels are set to the initial values between the time the model is downloaded and the time it is started.

Sample time

Base sample time of a multiple of the base sample time.

Base address

Enter the base address of the board. It is important that this entry corresponds to the DIP-switch settings on the board. For example, if the base address is 300 (hexadecimal), enter

0x300
