Eickhoff Bergbautechnik GmbH, headquartered in Bochum, Germany, is one of the leading producers of machinery and equipment for the mining industry. At Eickhoff, the so called Micos system is used for controlling their mining machinery. This system consists of a wired remote control, an LC display including a complex display controller and the actual Micos control unit.
The remote control serially transmits any command to the display controller at a baud rate of 9600, the controller on his part serially transfers all commands to the Micos control unit at the same baud rate. Due to this concept, the display controller is the most essential part of the Micos system and Eickhoff was urgently looking for a suitable replacement of the display and its controller, after this hardware had been terminated by its former distributor without substitution.
The replacing hardware was expected to be an LC display, as well, offering the previous resolution of 240 x 128 pixels. It should be fully able to handle all the tasks of serial communication with the remote control and the Micos control unit and should be very similar to the formerly used display as far as dimensions and design are concerned.
For this reason, NOFFZ was entrusted with the tasks of finding a suitable replacement for the display, developing a new display control unit, establishing serial communication with the two other components of the Micos system and finally producing the whole Micos display.
