Unable to control DC ports

[igorvin]

Hello,
I just receive Robo-Tank board and facing an issue to control DC ports

I have a Raspberry PI 2 board with Raspbian installed following the Software Installation Manual document

I successfully connect the temperature sensor and PH probe and can see data.
But when I trying to control DC ports I get nothing
When I checking voltage I didn't get 12 volts on the port
I tried to take pin +12v from the DC port and GND from the Grounds connector - I can see 12v   
It looks like the ports connected to pca9685 not responding
When I checking the I2C bus everything looks OK:

Code:

pi@raspberrypi:~ $ sudo i2cdetect -y 1         
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- 63 -- -- -- -- -- -- -- -- -- -- -- --
70: 70 -- -- -- -- -- -- --                        
pi@raspberrypi:~ $

This is my configuration in Reef-Pi software:

PCA9685 Driver:
        configured on Address:64 Frequency: 800

DC Port 4:
      configured as Outlets on Pin 12

In Reef-Pi I configured a new Equipment and connected it on Port: DC Port 4
 On/OF is not responding

I will be appreciated for your help to understand what I doing wrong 


Thanks in Advance
