SDC1130 Pinout

Greeting to all

I am having an SDC1130 controller which has the following pinout.


1. Does anybody know what do the P3 represent? I haven\'t found anything on the documentation or the datasheet.

2. Can I connect a PPM/FM receiver on \"Radio Connector\" pin on P4 and operate in closed loop speed control?
I believe that I cannot connect it to the DB25 port since the RCRadio is shared with the encoder (and I am using an encoder).

Thank you

The P3 is for manufacturing use only.

You\'ll want to use the DB 15 connector for your pulse radio input. Since the pulse radio inputs 1,2, and encoder lines are on the same lines, use either pulse input 3 and 4 instead of pulse input 1 and 2; pins 11 and 12.

Thank you for your answer
