APG Remote

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 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 levels are

defined as:

• standard TTL levels (0 V is logic true, + 5.0 V is false),

• fan- out is 10 ,

• input load is 2.2 kOhm against + 5.0 V, and

• output are open collector type, inputs/outputs (wired- or technique).

NOTE

All common TTL circuits operate with a 5 V power supply. A TTL signal is defined as "low"

or L when between 0 V and 0.8 V and "high" or H when between 2.0 V and 5.0 V (with

respect to the ground terminal).
