Abstract

Apparatus for displaying a plurality of remotely measured parameters. The data words representing the parameters have different scale factors and include a parameter identifier and a parameter value. The apparatus includes a decoder for determining from the parameter identifier the scale factor associated with a data word and a scaling circuit for scaling the parameter value. The scaling circuit can include binary dividers, one of which is selected by the decoder output. The scaled parameter value addresses a ROM which provides BCD digits for energizing a display unit associated with the parameter.
