Hello all,
I would like to connect 6 CS616 sensors and 6 107 Temperature probes to a AM16/32 multiplexer.
I tried to do it with short cut but it seems that can not connect 2 types of sensors to the multilplexer. Once one type is selected I can not choose another one.
Is it possible to do it ?
Thank you for your help,
Have a good day,
Fanny
Hi
you need to set the multiplexr as 4x16, so at each clock 4 channels of a group will be presented to the logger at the same time.
then between logger and AM16/32 using the commons:
COM H ODD -----> Vx1 excitation for all 107
COM L ODD -----> 1SE analog ch per all 107
COM H EVEN -----> Control port for enable all CS616
COM L EVEN -----> 2SE analog ch per all CS616
then the sensor to the varios groups of the AM16/32
107 black -----> H odd for excitation
107 red -----> L odd for SE ch
CS616 orange -----> H even
CS616 Green -----> L even
All shield (107 and CS616) -----> GND of the group between ODD a EVEN treminal
All gnd of 107 white or purple -----> gnd terminal near excitation or SE ch
All red 12V of CS616 to SW12 (best ) or 12V terminal but with a fuse (for safety it is always a good idea to protect the 12V cables that go to the soil probes)
All black of CS616 to G near 12V terminal
At each impulse it is necessary to take a reading of 107 and then the measurement of CS616, each time with different locations.
Remember not to enable CS616 if you are measuring 107. CS616s are a large source of electrical noise so when turned on it severely disrupts analog measurements.
