Nexus Softpatching

Softpatching  is  available  for  use  with  the  Nexus,  which  will  allow  you  to  utilize  the  internal                
software of the Nexus.  This step will need to occur before any BACnet programming takes place.  
For Standalone systems, this is the primar y programming function.

Programming Contact Closure or Station Inputs

Use the programming diagram to setup your system.  In this step contact closure buttons or station 
buttons will be programmed.  Each button and associated load will need to have its action pre -
determined before any programming takes place.    

Each system will have different programming characteristics and this document does not show all 
possible programming options. When Contact Closure Inputs are enabled they will always show up 
as Station number 16.   

Utilize Appendix IV and V for programming inter face explanations.

1.  Press the ‘STATION’ button multiple times until the LED is lit next to the Station Address that is 

to be programmed.

2.  Press the ‘BUT TON/INPUT ’ button multiple times until the LED is lit next to the Button that is to 

be programmed.

3.  Press the ‘BOARD’ button multiple times until the LED is lit next to the Firing Card that is to be 

programmed.

4.  Press the ‘OUTPUT ’ button multiple times until the LED is lit next to the Load that is to be  

 

programmed.

5.  Press the ‘RELAY AC TIONS’ or ‘DIMMER AC TIONS’ button multiple times until the LED is lit next 

to the Action that is to be carried out by either the relay(s) or dimmer(s).  If ‘AUTO OFF’ or ‘ TO 
AC TION’ is chosen, proceed to step 7.  If not, proceed to step 6.

6.  Press the ‘STATION’ or ‘BUT TON/INPUT ’ button to move to the next Station Address or Button that 

is to be programmed.

The next two steps are only to be used if the ‘Auto Off ’ Action has been chosen or the ‘ To Action’ 
has been chosen.

7.  Press the ‘ TIME’ button multiple times until the LED is lit next to the Time that the load is  

 

to turn off at when using the Auto Off Action.

8.  Press the ‘LEVEL’ button multiple times until the LED is lit next to the Level that the dimmer  

is to dim to when using the To Action.

9.  Press the ‘STATION’ button to move to the next Station Address that is to be programmed.
