DSP 1
You can also find out the status of the display by sending the following query and addressing the supply to talk:
DSP?
The response will be either a "1'' or a "0''.
Message Display Capability. The display command can also be used to display messages on the front panel. Messages may consist of a maximum of twelve alphanumeric characters. Only upper case alpha characters, numbers, and spaces will be displayed.
For example, to display the message "OUTPUT 2 OK” send the following command:
DSP "OUTPUT 2 OK"
NOTE | The BASIC programming statement for a series 200/300 computer would be as follows: |
OUTPUT 705; ''DSP'"'OUTPUT 2 OK""
