pattern may be changed by the user under software control. When power is first
applied to the boards all red LEDs should illuminate, fade, and then display a ran-
dom pattern.
Below each matrix of red LEDs are 3 more LEDs. The green and amber lights
are driven by the processor board’s CAN interface — the green light is the
board’s heart-beat, the amber light indicates a transmit of data. The red light is a
status light for an optional hard disk that is installed below the processor board.
Two LEDs in the top right hand corner of the display are driven by the module
controller. The green light is a heart-beat signal, the amber light flashes each time
the module controller is sending information over the CAN bus.
Module Identification Number
At the rear of the power supply unit are three dials — each represents one nibble
from a 12 bit network address, or netid. The netid for each module must be
unique and modules must be numbered sequentially starting from 0.
Enter each nibble of the address onto the dials using a suitable screwdriver.
Note: for two module systems the module id’s must differ in the least significant
bit only. Module id’s of 0 and 1, or 2 and 3 are therefore permitted, but 1 and 2
are not.
Warning – You must ensur e that the power is disconnected befor e setting the
module addr ess.
Additional Note for Revision A MK526:
Having identified a module’ s network address each nibble of the 12 bit address
is bit-flipped (e.g. 01 11 becomes 1110). The resulting 3 nibbles are then entered
onto the dials using a suitable screw driver .
The following table summarises the module id’ s for systems of up to 32 modules.
The dials for module 5, for example, must be set to 00A.
