DM6420 Digital Output block
Simulink® Real-Time™ Library for Real Time Devices
The DAS1601/16 has an 8255 chip with 2 ports (1,2). Each port has a maximum of 8 digital I/O lines that can be configured as inputs or outputs.
Use a separate driver block for each port. By selecting the digital output driver block, the port is configured as output.
Block Input Data Type
< 0.5 = TTL low
Enter numbers between 1 and 8 to select the digital output lines used with this port. This driver allows the selection of individual digital output lines in arbitrary 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
Number the lines beginning with 1 even if this board manufacturer starts numbering the lines with 0.
From the list choose either
The port name defines which port is used for this driver block. Each
port has a maximum of 8 digital lines that can be configured as outputs.
One block is required for each port used.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
Enter the base address of the board. This entry must correspond
to the DIP switch setting on the board. For example, if the DIP switch
setting is 300 (hexadecimal), enter
