Sign - Legends
The ID of a legend (or message) defines the message number which is received from the zone. The Legend Assigned
shows the defined legend which will be output to the sign. In the case of a rotating plank sign this legend is expressed as
a number. The number as expressed in the Legend Assigned field is interpreted by the sign control software into a bit
pattern. This bit pattern is used to drive the sign via an OTU.
On a rotating plank sign the legend number is translated into a bit pattern. This bit pattern is defined within the
Rotating
Prism Details window.
