CAN Bus Termination
Minipack systems are shipped from factory
with the CAN bus already terminated with
120Ω resistors.
To ensure a correct bus communication and
avoid data reflection, you must always
terminate the CAN bus with two 120Ω
resistors, one at each end of the line (60Ω
bus impedance). The figure shows a
Minipack system with its controller
communicating with the rectifiers via the
CAN bus.
CAN Bus Addressing
All rectifiers, Smartpack controllers and other control units connected to the Eltek Valere’s CAN
bus must have a unique address or ID number. The control system’s master controller assigns
automatically the rectifiers’ addresses (software assignment). The controller registers the
rectifiers’ ID numbers – or CAN bus address (01, 02 ...) – together with their Serial Numbers.
The control system’s controllers and control units use DIP switches for configuring their unique
CAN bus ID number (hardware assignment).
You can address a maximum of 14 control units of each type – Smartpack controllers, Smartnode
units, Battery Monitors, Load Monitors, etc. – to the control system’s CAN bus. See table below:

ID numbers formatted in italics (column 15 and 16 and range 65-78) are not available due to
software constraints. For DIP switch configuration, refer to chapter “CAN Bus Nodes”, page 24.
The figure shows a Minipack DC power system expanded with 3 CAN nodes to implement
additional digital inputs, relay outputs or similar functionality.
