18.2 Technical Description
General
This board performs two different functions:
•
Temperature control of the DMD devices.
•
Drive of the motors.
The command and control lines are software controlled and a local micro-controller communicates, via the I²C bus, with the main
CPU. An NTC resistor measures the temperature of the DMD and an active Pelletier-cooling element is switched on when a certain
temperature is reached. The active cooling status of each Pelletier device is visualized with yellow Leds.
The zoom and focus motors have an encoder so that their position can be precisely adjusted. This can be necessary to get an exact
position of the zoom and focus lenses per source. The other motors have a simple left/right or up/down control with an end of range
detection. They are driven with a dual power OPAMP.
Micro-Controller Section
The board has two wired connections with the Power Backplane, J520 for the connection with the CPU (I²C bus and an IRQ_DMD)
and J504 with a number of supply voltages.
The +TEC voltage is generated and adjusted on the SMPS and is applied via a MOSFET power switcher to the Pelletier active
elements.
