11. n of the different gels Note Over time the gel string may warp slightly This may alter the positions of the gels relative to their pre programmed DMX values and therefore some fine tuning may be required The motors have an optical encoder feedback system The purpose of which is to convert motor revolutions in to electronic pulses and also to determine which direction the motor is turning The electronic cards consist of three key components L298 motor driver 75176 Transceiver and a Processor The L298 is a true digital device receiving two PWM signals to operate speed and direction The 75176 transceiver operates in the receive configuration to convert serial protocol to a TTL level The processor is an OTP part containing proprietary software The majority of electronics problems are usually created by external factors such as shorted cables etc The 75176 transceivers are susceptible to damage if 24VDC is present on the DMX signal lines Routine maintenance can prevent most mechanically based problems The motor mounting plate can be adjusted to control tension on the belt Excessive belt tension is often the cause of noise and poor performance Conversely loose motor belts can cause accuracy problems Troubleshooting is a process of elimination First rule out the other field factors i e faulty cables power sources If an electronics problem is suspected try replacing the electronics card first If accuracy problems should occur
