SCH NOTES: On the P/S and Comms sheet, replace D3 and D4 with SMDJ36CA. Fix the Decoding. Use NAND gates. For the decoding, also switch to 2 input or 4 input gates, rather than the 6 input gate. The 6 input chip is pretty exotic and power hungry for what we are doing. Add an amplifier for the P_ISENSE_AMP_B signal. Based on the IRAM internal shunt resistor value (.0083 ohms), I think we'll need around 100x gain (this would give us a full-scale reading with a current of 6A). We'll need to transient protect the input of the gain stage and the A/D input. Eliminate the Elmo Interface J1. Add a Pull Up resistor for the signal P_TF_B ( FLT/IMON pin 19 of the IRAM Module ). 12k to +5V. Add limit inverters for the PROP CHANNEL. ( Limit signal HI = at limit ) 74HC1G32GW,125 Dgk 568-7732-1-ND Wire the signal P_TF_T to Limit_1 ( pin 16 ) of U5 ( PIC Servo SC ).I Use a Harwin connector for J3 instead of a C-Grid. Fix the Harwin Pin - Out's. Keep the Cu pours well away from the cut line.
