1.4 Non-IEEE-488 Communication Connections
Non-IEEE-488 communication connections on the 2996 Detector include:
• Analog Outputs – The 2996 Detector provides two, unattenuated, 1 volt-per
absorbance-unit analog output channels to integrators, chart recorders, or other
components.
• Event Inputs and Outputs – The 2996 Detector sends and receives contact closure
signals to and from other instruments.
You make all non-IEEE-488 communication cable connections to the 2996 Detector at the
rear panel on the analog/event terminal (Figure 1-2).
1.4.1 Connecting Analog Output Cables
The values of the analog output signals generated by the 2996 Detector are specified by
parameter values set from the Millennium
32
Workstation. For details, refer to the
Millennium
32
Help.
Required Materials
• One small, flat-blade screwdriver
• One electrical insulation stripping tool
• Analog signal cables (included with the Waters 2996 Detector Startup Kit)
Procedure
To connect the 2996 Detector to a device that receives analog output signals:
1. Pull off the analog out terminal strip from the 2996 Detector rear panel (Figure 1-5).
This step simplifies the following steps.
2. Insert the appropriate bare wires at one end of an analog signal cable into the
positive (
+
) and negative (–) terminals of Analog Out 1 (Figure 1-5). Tighten the
two screws to secure the
+
and – wires.
STOP
Attention: To meet the regulatory requirements of immunity from external electrical
disturbances that may affect the performance of this instrument, do not use cables longer
than 9.8 feet (3 meters) when you make connections to the screw-type barrier terminal
strips. In addition, ensure that you always connect the shield of each cable to chassis
ground.
