Block Parameters


Enter a vector of numbers between 1 and 4. Do not repeat channel numbers. For example, to use the first, second and fourth channels, enter

[1, 2, 4]

Number the channels beginning with 1 even if this board manufacturer numbers them beginning 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 replicated over the channel vector. 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, used by the block at initialization. If Reset vector has a value of 1, the board sets the corresponding channel to the value of the Initial value vector when execution stops. Enter a double precision voltage value in the range -10 to +10. This must be scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is replicated as initial value over the channel vector. The channels are set to the 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 (-1 means sample time is inherited).

Base address

Enter the base address of the board. This entry must correspond to the base address DIP switch settings on the board. For example, if the base address is 2C0 (hexadecimal), enter


Note that the Sensoray 526 board ships from the manufacturer with a base address of 0x2C0. If you want to change the base address, see the board manufacturer documentation for allowed values.
