Synchronization and Output Signals
68 TriPlus RSH Hardware Manual
Combining the TriPlus RSH with a GC requires synchronization of a Ready-Signal and a
relay contact output signal.
This section explains the available input and output signals, the pin allocations of the external
connectors, and provides information enabling you to copy the default signals and add, for
example, a second output signal if required.
Synchronization signals are inputs that inform the TriPlus RSH to wait or to proceed with a
sample-processing step.
Output signals are sent from the TriPlus RSH to the external devices, such as the GC, to
indicate the status or the completion of the processing steps.

To setup the synchronization signals
The synchronization signals from the system to the GC must be set step-by step.
1. Assign an Input and an Output signal, and establish the type of contact required to
receive or send a signal. Type of contacts are a TTL (Transistor-Transistor Logic), a relays
contact, an Opto-coupler or another type.
The required parameters such as Pulse Duration and Blocking Time must be added.
2. An output signal is required to send a start signal to the GC. Typically the Switch Out
Signal 1 (SWOut1) is used for this task.
The assigned signals must be matched with the pin allocation of the synchronization
cable.
A second output signal, named Destination Aux, can be used for cases where one
command is sent to two different GC which must be started at the same time.
A Y-shape synchronization cable is required for connecting the TriPlus RSH to the GCs.
One signal used could be SWOut1 and the second signal would be SWOut2.
The assigned signals have to be matched with the pin allocation of the synchronization
cable.
Synchronize the signal parameters with the GC System.
Refer to the section Input/Output Interface and to the section Signal in the TriPlus RSH
User Guide. The Ready signal is usually sent from the GC to the system; a TTL-In signal
is used to receive the Ready signal. Depending on the GC settings, the signal is set to
active high or active low.
3. Bundle the required Input Signal and Output Signals for the GC System. The bundle
can be configured and tested in the combination of the system, and the other device.
The bundling is described in the section Chromatograph System in the TriPlus RSH
User Guide as the last step in setting up signals.
