4.8 Remote Interface Remote Interface
Peripheral instruments connected such as Titrinos, Titroproces-
sors, pH Meters etc. can be controlled via the remote interface
(25-pin socket).
14 lines (Output 0–13) are available for the emission of signals.
For receiving signals (e.g. the "ready" signal of a Titrino at the end
of a titration) 8 lines are provided (Input 0–7).

The +5 V supply line may by charged with 20 mA maximally.
When the 759 Swing Head is connected to the remote interface,
the output lines 11–13 and the input line 7 are occupied. These
four lines are not continued in the plug and ignored, when further
instruments are connected via the remote cable (see page 15ff).
The coupling with Metrohm instruments with the standard cable

The Output lines 8…13 are unused by
other Metrohm instruments as yet.
They are assigned to pin 6…8, 13,
19…20.
