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).
Pin | Signal | Description |
|---|---|---|
|
1 |
DGND |
Digital ground |
|
2 |
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. |
|
5 |
|
Not used |
|
6 |
POWER ON |
(H) All modules connected to system are switched on. Receiver is any module relying on operation of others. |
|
7 |
READY |
(H) System is ready for next analysis. Receiver is any sequence controller. |
|
8 |
STOP |
(L) Request to reach system ready state as soon as possible (for example, stop run, abort or finish and stop injection). Receiver is any module performing run-time controlled activities. |
|
9 |
START REQUEST |
(L) Request to start injection cycle (for example, by start key on any module). Receiver is the autosampler. |
