Setting the remote lines

= initialize remote lines of 788
= initialize remote lines of 732/1 and 732/2
= run/stop time program at 732/1
= run/stop time program at 732/2
= run/stop IC Pump 709/1
= switch valve A at 733/1 to "Fill"
= switch valve A at 733/1 to "Inject"
= switch valve B at 733/1 to "Fill" or switch

suppressor to next position

= switch valve B at 733/1 to "Inject"
= trigger the autozero function at 732/1
= switch on pump at 752/753
= switch off pump at 752/753
= switch suppressor at 753 to next position
= run/stop IC Pump 709/2
= switch valve A at 733/2 to "Fill"
= switch valve A at 733/2 to "Inject"
= switch valve B at 733/2 to "Fill" or switch

suppressor to next position

= switch valve B at 733/2 to "Inject"
= trigger the autozero function at 732/2
= switch on pump at 754
(with 6.2143.220 cable)
= switch off pump at 754

arbitrary 14 bit pattern

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'

'ZERO 1'

Here the following is valid:

= line inactive

= line active

= do not change line state

Example:

***000*******1

= Output line 0 active

= start/stop time program at 732/1

For details about the remote interface, see section 5.1.

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 4.3.6 and section

5.2.
