The

CTL:Rm

command controls external instruments via the remote

interface. It causes the setting of defined line states or the sending

of pulses via the 14 remote output lines. Predefined bit patterns are

supported which can be selected by short names (e.g.

'INIT

732/819'

or

'ZERO 1'

).

Here the following is valid:

0

= line inactive

1

= line active

∗ = do not change line state

Example:

*************1

= Output line 0 active

= advances 797 VA Computrace

For details about the remote interface, see section 3.2.

Data communication via

RS232 interface

= start/stop time program at 732
arbitrary string of 14 characters

Using the

CTL:RS

command data (= character string) can be sent to

instruments connected via the serial RS232 interface.

For details about the remote interface, see section 2.4.4 and section

3.2.4.
