2.6.6 Trigger Input/Output / RS422 serial communication
The Trigger output use a Sub-D 15 female connector. This connector is used for trigger Input / Output
and for RS422 serial communication (Cf. Table 2-3 and Table 2-4).
The trigger options make the lighting cycle externally controllable and the synchronization between
e.g. a scanning system cycle and the CHRocodile CLS measurement rate. This means that external
triggering is possible for every measurement up to the full measurement rate of 2000Hz.
The interface contains the connection points for the synchronization and RS422 serial communication.
The serial RS422 is interfaced on the Sub-D15 female connector. Serial communication are mostly
used for sending command as a hyper-terminal. As the number of channel is high with a huge amount
of data, serial communication port cannot support data transfer.
