TMQ Autopilots are intended for use in three (3) basic configurations:
1. AP4 can be used to control most brands of drive units or solenoid
control valves (hydraulic). System components:
 Control unit
 Compass
 Rudder feedback unit
2. AP4 and mechanical drive system - used to drive most hand-operated
mechanical steering systems eg: rod & chain, push-pull or pull-pull
systems. Some helm pumps can also be used with a mechanical drive to
provide an installation, which requires no additional hydraulic pump.
System components:
 Control unit
 Compass
 Rudder feedback unit
 Mechanical drive
3. AP4 and reversing hydraulic pump - used with hydraulic steering
systems. Different pump units are used to cater for a wide range of
systems. Correct installation is required and pump size and voltage
should be considered BEFORE installing the hydraulic pump. System
components:
 Control unit
 Compass
 Rudder feedback unit
 Reversing hydraulic pump
