OUNTING
Non-slip rubber feet are included on all NCB modules to allow them to
conveniently rest on any horizontal surface. Four 6-32 threaded holes are also
available on the bottom of the module to allow bolting of the module in any
convenient orientation. WARNING: Care should be taken to limit protrusion
of the screw into the module to no more than 0.125 inch from the module bottom surface!
Mounting kits are available as options to allow wall or rack (19” EIA) mounting
of the NCB module.
When wall or rack mounting the NCB, a suitable safety and protective earth
ground should be provided to the metal enclosure. The protective earth ground
provides a path to ground for electrostatic discharge (ESD) energy. This
connection is most conveniently made directly to the wall mount bracket or rack plate.

OPTION A Switches
OPTION A switches set the LonWorks addressing parameters (switches 5 and 6). Leave the unused switches
in the UP position. The position of the OPTION A switches are read by the NCB at module power-up or after
pressing the “RESET” button on the front panel.

Setting the LonWorks Addressing Parameters (Switches 5 and 6)
Switches 5 and 6 provide a simple (but very limited) method of setting the LonWorks domain/subnet/node
address of the internal Control Neuron Processor. This method is useful for systems with two NCB modules,
but does not provide enough flexibility for larger systems. (Standard Network Management Tools are a much
better choice.) For more information on setting this address, see “S
for a tutorial on network management tools.
If OPTION A Switch 5 is UP, Switch 6 determines a static subnet/node address for the Control Neuron
Processor: Switch 6 DOWN fixes the Control Neuron Processor subnet/node address at 255/1 in the
zero-length domain, while Switch 6 UP fixes the subnet/node address at 255/2 in the zero-length
domain. This setting allows for a quick evaluation of the NCB modules, requiring minimal user setup.
