Appendix E: Module EIB mode and Stand-alone Mode
The NH

CAN module can be used in conjunction with a display head (EIB mode) or on its own
(Stand-alone mode). When delivered to be used with a display head, the module is setup in EIB
mode. When delivered to be used alone, the module is setup in Stand-alone mode.
In EIB mode, the module is polled by the display head and the data transmission is synchronized
on the CAN bus via the CANopen protocol. The module must be in EIB mode when on the EIB
bus with a display head. When in Stand-alone Mode, the module broadcasts its data on the
500kbps CAN bus at the programmed broadcast rate (see section 4.0 and section 8.6).
The module must be properly configured in EIB mode or Stand-alone mode depending on how it
will be used.
To convert from one mode to the other requires software reprogramming of the lambda module
followed by the removal (set to EIB) or installation (set to Stand-alone) of a jumper inside the
module.
To convert a module from Stand-alone to EIB Mode
1. Connect the lambda module to a power supply and a PC (via a CAN communication
adapter) using the cabling shown below. A sensor does not have to be connected to the
module. Note that only one module is connected and the display head is not involved.
