Remote Interface
The APG remote connector may be used in combination with other analytical
instruments from Agilent Technologies if you want to use features such as
common shut down, prepare, and so on.
Remote control allows easy connection between single instruments or systems
to ensure coordinated analysis with simple coupling requirements.
The subminiature D connector is used. The module provides one remote
connector which is inputs/outputs (wired-or technique).
To provide maximum safety within a distributed analysis system, one line is
dedicated to SHUT DOWN the system’s critical parts in case any module
detects a serious problem. To detect whether all participating modules are
switched on or properly powered, one line is defined to summarize the
POWER ON state of all connected modules. Control of analysis is maintained
by signal readiness READY for next analysis, followed by START of run and
optional STOP of run triggered on the respective lines. In addition, PREPARE
and START REQUEST may be issued. The signal level is defined as:
•
standard TTL levels (0 V is logic true, + 5 V is false),
•
fan-out is 10,
•
input load is 2.2 kOhm a 5 V, and
•
outputs are open collector type, inputs/outputs (wired-or technique).

PREPARE
(L) Request to prepare for analysis (for example, calibration,
detector lamp on). Receiver is any module performing
pre-analysis activities.
3
START
(L) Request to start run / timetable. Receiver is any module
performing run-time controlled activities.
4
SHUT DOWN
(L) System has serious problem (for example, leak: stops
pump). Receiver is any module capable to reduce safety risk.
