Required tools and materials
•
Small, flat-blade screwdriver
•
Electrical insulation stripping tool
To connect signal cables from other HPLC system devices to the I and II
terminals on the rear panel of the detector:
1. Remove terminal I or II (see
2. Unscrew the connecting pin terminal.
3. Using the stripping tool, strip the wire about 3 mm (1/8 inch) from the end.
4. Insert the stripped wire into the appropriate connector.
5. Tighten the screw until the wire is held securely in place.
6. Reinsert the terminal.
7. Press firmly to ensure that it is inserted fully.
2.6.2 Connecting signal cables from the rear panel and
Ethernet connectors to the detector
The rear panel of the detector provides two analog connectors and an Ethernet
communications port for operating the detector with external devices.
Make the signal connections to your detector, considering the following conditions:
•
Operating mode you select for the detector (stand-alone or remote control)
•
Types of instruments that make up your HPLC system
This section describes the input/output (I/O) and digital signal connections that you
can make from the two rear panel connectors and the Ethernet connector.
2.6.3 Making Ethernet connections
The detector’s rear panel also includes one Ethernet interface connector for digital
signal communications. Use this connector for devices such as these:
•
Network adapter card in the Empower workstation
•
Solvent manager
Analog 2
2
2 V full-scale analog output signal of channel B
(scaled to the current AU setting).
Switch 1 (2)
Used to connect to a fraction collector. Can be
controlled by threshold and timed events.
Switch 2 (2)
1. Inject Start, Chart-mark, Autozero, and Lamp inputs are configurable from the detector first
Configuration screen by setting the appropriate parameter to High. See for more detail.
2. See the discussion of attenuation in the detector analog outputs in
electricity source” on page 30
