Simple convert: from "position" to "angle" value for: KRS 2552 HV servo motor

KRS-2555RHV Servo Specs:

• Maximum Operating Angle 270º

• Maximum Holding Torque 14kgf.cm (11.1V)

• Speed 0.14s/60º (11.1V, under no load)

• ICS 3.5 protocol (Serial and PWM comunication)

• Size 41x21x30.55 mm

• Weight 41.5g

• Operating Voltage 9V~12V

For a serial servo motor, a rotation range from 3500-11500 is possible. The middle value, 7500, is referred to as a neutral position. And the angle range from 0 to 270 degrees. 

Therefore to convert: 

1 degree = (11500-3500)/270 = 800/27 
with rc4.dll. use positions to generate a command. 
to convert: 90d ->( 3500+90*800/27 )
