5.1.1 The User Control Module (UCM)
The UCM is the brain, or the main computer, of the DX System. The UCM is built into
every Master Remote.
The UCM is responsible for
• System wake-up and shutdown
(the UCM is connected to the system on/off switch)
• System safety, diagnostics, status and fault codes
• System backup and restore
• DX BUS testing and operation
• Reading the input commands (desired speed and direction, actuator position
switches) from the Physical User Interface and all external remotes and
modules
• Generating the output commands (calculated speed and direction, actuator
control) and sending these over the DX BUS to the Power Module and fitted
auxiliary modules
• all system drive algorithms
• all programmable system parameters.
• RS232 serial communication with programming tools (HHP or Wizard)
The UCM has had several software revisions:
• - (dash)
• A
• C
The available parameters and their meaning are slightly different between software
versions. See the programming section for a list of all parameters.
5.1.2 The physical user interface
The physical user interface translates the physical inputs (buttons, joystick) into
electrical signals it sends to the UCM. It also translates the electrical outputs of the
UCM to visible or audible user signals (LEDs, displays, the horn).
The Physical User Interface always consists of
• the housing
• the System Status LED
And optionally
• a joystick
• a display
• a battery gauge
• a battery charger socket
• buttons and knobs
• connectors for external switches
Most Master Remotes have their own user input device in the form of a joystick, but
this is not always the case. For example: the G91 does not have a joystick, it depends
on either a Secondary Remote or a set of switches to obtain direction and speed
commands.
