The BV4511 controller is supplied by ByVAC and features a nice cool-blue display with colors and graphics-drawing abilities. The complete datasheet can be found locally 1).
The big display that attaches to it is VT100 command compatible and the reference sheet allows us to create a program that will output data to the screen that is suitable for monitoring systems. The display lacks many capabilities, compared to the bv4141, but the size and luminosity of the display can be used to easily attract attention to important events.
