2. SETUP AND OPERATION
STEP 1. MOUNTING
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.
STEP 2. SWITCH SETUP
OPTION A Switches
OPTION A switches set the internal modem configuration (switches 1, 2, 7, and 8), and LONWORKS
addressing parameters (switches 5 and 6). Leave the unused switches (3 and 4) 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.
