Driver Block Parameters
Channel vector -- Enter a vector containing channel numbers between 1 and 16. This driver allows the selection of individual D/A channels in any order. The number of elements defines the number of D/A channels used. For example, to use the first and second analog output (D/A) channels, enter
Number the channels beginning with 1 even if the board manufacturer starts numbering the channels with 0.
Range for bank 1, Range for bank 2 -- Bank 1 consists of channels 1-8 and bank 2 consists of channels 9-16. The output range may be specified on a per-bank basis. These ranges must correspond to the jumper settings in header R4 on the board. See the board manual for details.
Note that if you select a range of either -5V to 5V or 0 to 5V for one bank, then it is not possible to select a range of either -10V to 10V or 0 to 10V for the other bank. This is because jumper 5 in header J4 (On-Board Reference Full-Scale Voltage Selection) affects all channels, not just those of a single bank. See the board manual for details.
This driver supports the Adjustable Reference Voltage. You can use this feature with either output range -2.5V to 2.5V or 0 to 2.5V. If for example you adjust potentiometer R4 to 2.3V (instead of the default setting of 2.5), then an input signal of 1.2 will result in an output voltage of 1.2 / 2.5 * 2.3V = 1.1V. See the board manual for details.
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. If you provide a value that is out of the channel's range, the value is reset to the lower or upper range value.
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
