46 Agilent 7890B Installation
1 Installing the GC
SAMPLER 2 Optional. A second injector, usually the back
injector. (For 7693A/7650, the GC automatically senses the
injector location. For a 7683 injector, typically configure this
injector as INJ2.)
TRAY Optional. The 150-position sample tray (includes
optional barcode reader/heater/mixer control, if purchased).
The AUX connector
Do not use. This connector is reserved for future development.
The SIG (analog output) connectors
Optional. Use SIG1 and SIG2 for analog output signals.
REMOTE connector
Provides a port to remotely start and stop other instruments
using the APG protocol. A maximum of 10 instruments can be
synchronized using this connector. See “Using the Remote
Start/Stop Cable” on page 78 for more detail.
EVENT connector
This connector provides two passive contact closures and two
24-volt outputs for controlling external devices. The outputs are
controlled by valve drivers 5 through 8.
