The averaging values can be reset to factory default (375) by issuing the ECM OS Command
0x15 (see Appendix B).

Changing the NID
The Node ID (NID) can be programmed from 0x01 to 0x7F (1 to 127). To change the NID,
several messages must be sent to the NOxCAN module. This must be followed by a reset of the
module (that can be performed three different ways; see the following).
Start by sending the following message to place the module into pre-operational mode.
CAN id
byte 0
byte 1
0x00 0x80 NID
The next message(s) place the module(s) into LSS (Layer Select Services) configuration mode. If
there is only one CANopen module on the CAN bus this process requires only one message. If
there are several CANopen modules on the same CAN bus the specific module must be
identified using Product Code, Revision Number and Serial Number, (these can be found on a
white label placed on the top of the plastic enclosure).
MULTIPLE MODULES ON BUS
SINGLE MODULE ON BUS
The module will reply with byte 0 = 0x44 on CAN id 0x7E4 if it enters LSS configuration mode
successfully.
The next message sent contains the new NID as an unsigned hexadecimal character.

The module will reply with byte 0 = 0x11 and byte 1 = 0x00 on CAN id 0x7E4 indicating a
successful NID change.
