Introduction to the Quaternary Pump
Agilent 1100 Series Interfaces
APG Remote Interface
The APG Remote connector may be used in combination with other
analytical instruments from Agilent Technologies if you want to use features
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 quaternary pump 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 are defined as:
• standard TTL levels (low = 0.0 - 0.8 V, high = +2.0 - 5.0 V)
• fan-out is 10,
• input load is 1.7 kOhm against + 5 V, and
• output are open collector type, inputs/outputs (wired-or technique).
RS-232C
The RS-232C connector is used to control the instrument from a computer
through RS-232C connection, using the appropriate software . This connector
can be configured with the configuration switch module next to the GPIB
