Seven-Segment Indicator
In addition to the RUN and ERR indicators, User Defined CAN Units have a 2-digit, 7-segment dis-
play that normally indicates the enabled or disabled status of the communication. When an error
occurs, the seven-segment indicators will display a (flashing) error code.
There are dot indicators in the lower-right corner of each digit. The left dot of these two indicators
shows whether or not the Unit is configured with message commands (ST4 or ST5). The right dot
indicator shows whether the communication is enabled or disabled. the dot is lit when the communi-
cation is enabled (ST5).
