b. In the Start Instrument column, click the blank field to the right of the appropriate
triggering device (typically an autosampler). The word Yes moves to this field.
c. Click OK to save the setting and close the Change Instruments In Use dialog box.
6. Complete the remaining selections in the Run Sequence dialog box.
7. Click OK to save the settings, close the dialog box, and start the sequence or queue it.
External devices that are not controlled by the Xcalibur data system must be properly
connected for contact closure, and the appropriate instrument must be selected as the start
instrument in the Xcalibur Run Sequence dialog box.
To connect an external device, such as a liquid chromatography system, to your
LTQ Series MS detector, follow these procedures:
• Making Contact Closure with Devices Not Controlled by Xcalibur
• Starting a Sequence Run from Xcalibur
To connect the contact closure cable
Note To start data acquisition on the LTQ Series, the output (start) signal from the
external device must be Normally Hi (+5 V) and momentarily go to Low. If you cannot
configure the external device to go from Normally Hi to Low momentarily, it cannot be
used with the LTQ Series.
1. Connect the 2-wire trigger cable (in kit P/N OPTON-21705) to the Start In pins on the
power entry panel of the LTQ Series MS detector.
2. Connect the cable to the contact closure terminal of the external device, following the
wiring scheme listed in
