Appendix C: C3 Submersible Fluorometer Wiring and Cable Guide
The C3 Submersible Fluorometer outputs digital data in three formats: 1) Digital
data that can only be read by C3 Submersible Fluorometer’s software, 2) Digital
data in ASCII format that can be read by larger multi parameter systems such as
CTD’s, and 3) Digital data that can be read and converted to analog data by the C-
Series Analog Adapter.
An 8-pin Impulse cable provides two end connections: 1) a 9-pin RS232 serial port
for connection to a PC or laptop computer and 2) a 12V port for supplying power to
the unit.
