The gain multipliers can be used to multiply the value of the DC Gain (potentiometer) setting on the front panel of the Dynaserv drive. The DC Gain pot can be set for values of .5 to 5.5. There are two way to increase these values with a multiplication factor.

  1. There is a jumper setting on JP1 labeled GAIN H. With the jumper ON, the DC Gain pot setting will be multiplied by 13.

  1. There are DC gain multiplier circuitry that can be accessed on CN1(50 pin Honda connector). The circuit requires an external 5 to 24 VDC supply. Pins 34 & 35 is Gain Low(GL), 36 & 37 is Gain Medium(GM), and 37 & 38 is Gain High(GH). NOTE: Even numbers are + and odd numbers are GND.
