6. (Optional) Select the Enabled checkbox for SIM 2 and repeat steps 5a—5d for a
second external detector.
7. Click OK.
To disable the connection
 On the Device Input tab, clear the Enabled checkbox for the device and click
OK.
Note: Disabling the SIM connection does not turn off the detector.
Device Output Tab
You can convert digital NGC data to analog voltage via the SIM and output the
voltage to an external recording device, such as a light scattering detector. The SIM
converts and outputs NGC trace information as voltage through its digital-to-analog
converter (DAC) channels. When enabled, the external device can receive the
converted trace information. For the device you can define its
 Signal type
 Minimum and maximum output range (from 0–10 volts)
 Minimum and maximum unit range
To enable output to external devices
1. Ensure that the SIM is connected to the NGC instrument.
2. On the back of the SIM, ensure that the device is connected to DAC A.
3. Select File > System Settings to open the System Settings dialog box.
4. Choose the Device Output tab.
