2.6.9 Devices on the remote interface
External peripheral devices such as pH meters, pumps, etc. can be con-
trolled via the remote interface (25-pole socket) of the Titroprocessor. Each
717 Sample changer also has a remote socket which can be controlled via
the
'External bus'.

8 lines are available for signal output (Output 0-7). The remote socket of the
717 Sample changer has 14 output lines available (Output 0-13).
For receiving signals (e.g. the "ready" signal from a Metrohm instrument)
there are 8 lines available (Input 0-7).

The control lines of the 796 Titroprocessor are purely signal leads (TTL-level)
and should not be misused for supplying devices.
Remote connections can be used with specially assembled cables to solve
complex connection problems in automated systems.
Connection of Metrohm instruments is solved in the following manner with

Output lines 8…13 can only be used
with the 717 Sample changer, but are
not used as input lines for Metrohm in-
struments. They are laid 1:1 on Pin
6…8,13,19…20.
