32 Point Multiplex Modules—Multiplex Binary
The LED indicators (Figure 27) supply evidence of the module's
condition, and help determine that the module is functioning properly.
Figure 27: Identification of LED Indicators on XBN
LEDs indicate state of inputs 1-16 as received by
the microprocessor. LED orientation is software
programmable, defined as On for either contact
closed/voltage present or contact open/voltage
absent.
LEDs indicate the state of Inputs 17-32.
N2 Receive LED On indicates that data is on
the N2 Bus. N2 Transmit LED On indicates that
the module is responding on the N2 Bus.
After self diagnostics, lighted Error LED indicates
microprocessor error or reset. Lighted Power
LED indicates that the module is energized.
