16.5 APPENDIX E - GPIO PORT
The 9 pin SubD
GPIO
connector on the back of the Streamer Max MKII features two General Purpose inputs and two
General Purpose binary outputs. The inputs are polarised Optocoupler inputs, while the outputs are Open Collector
outputs. They can be used to send commands to the device and to carry out specific functions. The inputs feature
polarized photo couplers on each input and a 150 Ohm protection resistor is always installed in series inside. The
maximum current that can circulate on each photo coupler is 20mA. The voltage supplied between pin 8 and pin 1 is +5
V dc non-stabilised.
