Multi Unit Configuration
There can be up to 8 PDU modules units on the same CAN bus. If more than one PDU is used on a CAN
bus then the unit ID for each module needs to be set. If only 1 unit is to be used simply leave all the Config
pins disconnected and ignore the rest of this section.
For multiple units
to
function
in a single CAN
bus,
the
PDU’s need
to be
assigned one
of
8
Unit
ID’s,
each
using unique receive and transmit CAN message addresses. To assign the Unit ID, the 3 config pins on the
main connector (pins 10, 16 and 24) are either left open circuit (O/C) or connected to GND (Pin11).
The following table lists the configuration pin settings and the resulting 8 possible unit IDs.
