B-10 External Connections
Sample manager I/O signal connectors
The rear panel of the sample manager includes a removable connector that
holds the screw terminals for I/O signal cables. This connector is keyed so that
it can receive a signal cable inserted only one way.
Requirement: A contact closure output connection (Inject Start Out) from the
sample manager is required to trigger a mass spectrometer or an ACQUITY
2996 PDA detector running under MassLynx software control to start.
