RJ45 Ethernet jack Ports specifications
#1
Hello,

I'm in the process of replacing and adapting a number of protocols in wich bcontrol was being used to the bpod setup.
Could I get some information about the ports (the A31442-N Ethernet Jack ones) and the way its 8 pins are specified? Is it the same, with the Digital Input, Digital Output, GND, +5V, +12V, -12V, Analog Input and Analog Output?


Thank you!

Hi Beatriz

As you face the Ethernet jack, the port wiring for Bcontrol was (from left to right):
1. Analog Input (Used for photo-gate)
2. Digital Output 1 (N/C)
3. Digital Output 2 (LED)
4. VCC (+5VDC, used for infrared emitter)
5. GND (Digital)
6. +12VDC (power for valve)
7. GND (MOSFET Drain, for 12V valve)
8. Analog Output (N/C)

Bpod 0.5 does not have analog input or output lines - though we will add analog functionality in the near future.
As you face the Ethernet jack, the Bpod port pinout is:
1. Digital Input (Used for photo-gate)
2. 3.3V
3. PWM Digital Output (3.3V, for LED)
4. VCC (+5VDC, used for infrared emitter)
5. GND (Digital)
6. +12VDC (power for valve)
7. GND (MOSFET Drain, for 12V valve)
8. N/C

I hope this helps! It will be added to the wiki soon, with a diagram showing the layout.

Hi,
Could you please specify the pin out for the Serial ports as well? Can't find it anywhere.
Thanks,

Hi Marton,

For state machine r0.7 - 2.0:

As you face the Module jack on the state machine (with pin#1 on the left), the lines are:
Pin#1: Y (RS-485 non-inverting driver output)
Pin#2: Z (RS-485 inverting driver output)
Pin#3: B (RS-485 inverting receiver input)
Pin#4: A (RS-485 non-inverting receiver input)
Pin#5: Power supply GND (isolated from other channels and state machine digital ground)
Pin#6: Power supply +9VDC (supplies up to 100mA per channel)
Pin#7: Reserved for future use
Pin#8: Reserved for future use

More information about the first 4 pins is available in the RS-485 IC datasheet, here (see table 7).

I hope this helps!

-Josh
