Press to execute the command.

Using the letter keys to directly access and send commands is much faster than using the Select keys to find and then send commands. Of course, this method is faster only if you know which commands you are going to program. The following sequence shows the same example using the letter keys:

Press to execute the command.

Query Example

Queries return data from the addressed module. Use the Select keys or the letter keys to construct and send queries to the addressed module in the same way that you send commands. When you enter the query, the display returns a value. In the following example, the power module is queried as to its actual voltage output:
