Boreal Laser Inc. GasFinderFCr Operation Manual — Data I/O July 17th 2017
The DB15F connector on the back of the instrument is a hybrid data I/O connector, combining
serial data output (RS-232) and analogue signals useful for examining system performance.
The cable details are shown on page 3.10 of this manual.
Note: I/O equipment may be connected or disconnected while the system is operating.
Caution should be observed that data
may be compromised during transition.
